Description

  The present invention relates to a building air conditioning system.

  In a building such as a house, there is a case where a whole-building air conditioning system that performs whole-building air conditioning using a common air-conditioning apparatus is provided (for example, see Patent Document 1). In the entire building air conditioning system, conditioned air (cold air or warm air) generated by the air conditioner is supplied to each room in the building through the air conditioning duct so that the air conditioning (cooling and heating) of each room is performed. . In addition, since the entire building air conditioning system is basically operated at all times, the air conditioning of each room is always performed.

JP 2016-130624 A

  By the way, there are cases where it is relatively easy to spend without air conditioning in the relatively cool morning time zone even in summer and in the warm daytime zone even in winter. Therefore, in such a case, it is conceivable that the resident stops the operation of the air conditioning system (air conditioner) manually. When the operation of the air conditioning system is stopped, the room temperature increases in the summer, and the room temperature decreases in the winter. When the resident feels heat or cold, the operation of the air conditioning system is resumed and the room is air-conditioned.

  Here, when an elderly person or the like who has a dull sense of heat or cold lives as a resident, even if the temperature of the room rises or falls, it is assumed that the person is not aware of it. In that case, the resident will stay in a room where the temperature has risen or fallen without resuming the operation of the air conditioning system, so the resident will become ill, such as getting a heatstroke or catching a cold. It can be considered.

  This invention is made | formed in view of the said situation, and it can prevent that users, such as a resident, worsen physical condition by the temperature rise or temperature fall of indoor space accompanying the operation stop of an air conditioner. The main purpose is to provide a building air conditioning system.

  In order to solve the above-described problem, the air conditioning system for a building of the first invention is an air conditioning system for a building including an air conditioner that cools or heats a plurality of indoor spaces as air conditioning targets, and the temperature of each indoor space is controlled. In the case where the operation of the air conditioner is stopped based on the temperature acquisition means to be acquired and the operation stop operation by the user, any one of the temperatures of the indoor spaces acquired by the temperature acquisition means is a predetermined temperature. Control means for performing an operation start process for automatically starting the operation of the air conditioner or reaching the user for an operation start operation of the air conditioner when the air conditioner is reached.

  According to the present invention, when the operation of the air conditioner is stopped based on the operation stop operation by the user (for example, a resident), the temperature of each indoor space that is the air conditioning target is acquired. Then, when any of the acquired temperatures of the indoor spaces reaches a predetermined temperature, the operation of the air conditioner (cooling operation or heating operation) is automatically started, or the air conditioner A notification process that prompts the user to start driving is performed. In this case, for example, when the cooling operation is stopped in summer, when the temperature of any indoor space rises remarkably, the cooling operation is automatically started or the user starts the cooling operation. Can be. In addition, when the temperature of any indoor space is significantly reduced when the heating operation is stopped in winter, the heating operation is automatically started or the user is caused to start the heating operation. be able to. Thus, even when the user does not notice that the temperature of the indoor space has increased or decreased when the air conditioner is stopped, the air conditioner can be restarted automatically or manually. It is possible to prevent the user from deteriorating his / her physical condition due to the temperature increase or temperature decrease of the indoor space due to the stop.

  A building air conditioning system according to a second aspect of the present invention includes, in the first aspect of the invention, an automatic operation prohibition mode that can be set by a user operation as a control mode when the air conditioner is stopped. When the automatic operation inhibition mode is set, the operation start processing of the air conditioner is not performed.

  For users who are not good at air conditioning due to cooling or the like, it may be desired to stop the operation of the air conditioner for a certain period of time. In the case of such a user, when the operation of the air conditioner is automatically started, it is assumed that the user feels uncomfortable or the like. Therefore, in the present invention, when the user is set to the automatic operation prohibition mode, the operation of the air conditioner is not started even when the temperature of the indoor space reaches a predetermined temperature. Thereby, it can prevent that a user feels discomfort etc. by the driving | operation restart of an air conditioner.

  In the building air conditioning system according to a third aspect of the present invention, in the second aspect, the predetermined temperature is the first temperature, and the control means is controlled by the temperature acquisition means even when the automatic operation inhibition mode is set. When any one of the acquired temperatures of the indoor spaces reaches a second temperature that deviates from the first temperature with respect to the set temperature of the air conditioner, the operation start process of the air conditioner is performed. It is characterized by performing.

  By the way, even a user who is not good at air conditioning may deteriorate his / her physical condition when the temperature of the indoor space is significantly increased or decreased. On the other hand, it is considered that such users are less sensitive to heat and cold, and may not be aware even if the temperature of the indoor space is significantly increased or decreased. Therefore, in the present invention, in view of these points, even when the automatic operation prohibition mode is set, when the temperature of the indoor space reaches a second temperature that deviates from the first temperature with respect to the air conditioning target temperature, the air conditioner Is going to start driving. Thereby, even when the automatic driving prohibition mode is set, the user can be prevented from getting sick.

  A building air conditioning system according to a fourth aspect of the present invention is the air conditioning system according to any one of the first to third aspects, further comprising at-home determination means for determining whether a user is at home in the building, wherein the control means includes: When the home determination means determines that the user is at home, the operation start process of the air conditioner is performed.

  According to the present invention, the operation of the air conditioner is started on the condition that a user such as a resident is at home in the building. That is, in this case, since the operation of the air conditioner is not started when the user is not at home, it is possible to avoid operating the air conditioner unnecessarily even when the user is absent.

  A building air conditioning system according to a fifth aspect of the present invention is the air conditioning system according to any one of the first to fourth aspects, wherein the control unit starts operation of the air conditioner even after a predetermined time has elapsed since the notification process was performed. If not, the operation start process is performed.

  According to the present invention, if the operation of the air conditioner is not started even after a predetermined time has elapsed since the notification process for prompting the user to start the operation of the air conditioner is performed, the operation of the air conditioner is automatically started. Is done. Thus, even when the user is taking a nap or the like and is not aware of the notification process, the air conditioner is operated after a predetermined time has elapsed, so that the user is prevented from getting sick even in such a case. It becomes possible.

The top view which shows the floor plan of a building. The figure which shows the electrical constitution of an air conditioning system. The flowchart which shows an air-conditioning control process.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, it is assumed that parents and their children live in the building as well as their grandparents (elderly people). FIG. 1 is a plan view showing a floor plan of the building, and an outline of the building 10 will be described below with reference to FIG.

  As shown in FIG. 1, the building 10 is provided with living rooms 11 to 13, a bedroom 14, a machine room 15, and a corridor 16 as indoor spaces. Among the living rooms 11 to 13, the living room 11 is composed of a living dining room (LD) having a living room and a dining room, for example, the living room 12 is a children's room where children stay, and the living room 13 is where grandparents stay. It is a room for grandparents. In addition, each living room 11-13 may be a Western-style room or a Japanese-style room. The bedroom 14 is the parent bedroom of the parents, and the machine room 15 is an installation space for the air conditioner 21.

  The corridor 16 leads to each of the living rooms 11 to 13, the bedroom 14, and the machine room 15. These rooms 11 to 15 can be accessed through the corridors 16 through the entrances 18a to 18e. Doors 19a to 19e are provided at the entrances 18a to 18e. Of the doors 19a to 19e, the doors 19a to 19d are made of hinged doors, and the door 19e is made of a folding door. Each of these doors 19a to 19e is undercut at the lower end side, and the lower part of the doors 19a to 19e is a ventilation portion that communicates the rooms 11 to 15 with the hallway 16.

  Next, an air conditioning system provided in the building 10 will be described.

  The air conditioning system is configured as an entire building air conditioning system that performs air conditioning (cooling and heating) on a plurality of indoor spaces as air conditioning targets by the air conditioner 21 installed in the machine room 15. In the building 10, the living rooms 11 to 13 and the bedroom 14 are subject to air conditioning by the air conditioner 21 among the indoor spaces. In the following description, these indoor spaces 11 to 14 are referred to as air-conditioned spaces 11 to 14.

  The air conditioner 21 is configured as an indoor unit having a cooling function and a heating function. The air conditioner 21 has a take-in portion (not shown) that takes in the air in the machine room 15, and adjusts the temperature of the air taken in from the take-in portion to obtain conditioned air (cooling air or heating air). Generate.

  A plurality of air conditioning ducts 22 are connected to the air conditioner 21. Each of these air conditioning ducts 22 extends to each of the air conditioned spaces 11 to 14 and is connected to an air outlet 23 provided in each of the air conditioned spaces 11 to 14. Each air conditioning duct 22 is provided, for example, on the ceiling of an indoor space, and each outlet 23 is provided, for example, on the ceiling of each air conditioning space 11-14. In FIG. 1, for convenience, each air conditioning duct 22 is indicated by a broken line.

  Air-conditioned air (cold air or warm air) generated by the air conditioner 21 is supplied to the air outlets 23 of the air-conditioned spaces 11 to 14 through the air-conditioning ducts 22, respectively. Then, the supplied conditioned air is blown out from the outlets 23 to the indoor spaces 11 to 14. Thereby, the indoor spaces 11 to 14 are cooled or heated by the conditioned air (cold air or warm air) blown out.

  Incidentally, the conditioned air blown into the air-conditioned spaces 11 to 14 then flows into the corridor 16 through the vents under the doors 19a to 19d, and further flows into the machine room 15 from the corridor 16 through the vents under the door 19e ( Reflux). That is, the building 10 is provided with a reflux path for returning the conditioned air blown into the indoor spaces 11 to 14 to the machine room 15, and the air conditioner 21 supplies the conditioned air returned to the machine room 15 through the return path. Recapture conditioned air. Thus, this air conditioning system is a circulation type air conditioning system that performs air conditioning while circulating indoor air.

  By the way, it is not necessary to air-condition (cool) the air-conditioned spaces 11 to 14 by the air conditioner 21 in a relatively cool morning time even in the summer or in a relatively warm daytime even in the winter. It may be easy to spend. Therefore, in such a case, it is considered that the resident may stop the operation of the air conditioner 21 by manual operation. When the operation of the air conditioner 21 is stopped, the temperature in the building 10 (air-conditioned spaces 11 to 14) rises if it is summer and falls if it is winter. And when a resident feels heat and cold, it is thought that the driving | running of the air-conditioning apparatus 21 is restarted and air-conditioning space 11-14 is air-conditioned.

  Here, in the main building 10, grandparents live as residents. Because grandparents are elderly people, it is thought that their sense of heat and cold is dull. Therefore, even when the temperature in the building 10 rises or falls when the air conditioner 21 is stopped, it is assumed that the grandparents do not notice it. In that case, the grandparents do not restart the operation of the air conditioner 21. It will remain in the air-conditioned spaces 11 to 14 where the temperature has increased or decreased. If it does so, there is a concern that the grandparents may become sick, such as heat stroke or catching a cold.

  Therefore, in the present air conditioning system, in consideration of these points, when the temperature of the air-conditioned spaces 11 to 14 is significantly increased or decreased when the operation of the air-conditioning apparatus 21 is stopped, control for automatically starting the operation of the air-conditioning apparatus 21 is performed. ing. Therefore, a configuration related to such control will be described below.

  Each of the air-conditioned spaces 11 to 14 is provided with a room temperature sensor 25 as temperature detecting means. The room temperature sensor 25 is a sensor that detects the temperature of the air-conditioned spaces 11 to 14 in which the sensor 25 is provided, that is, the room temperature. The room temperature sensor 25 is provided on the wall surfaces of the air-conditioned spaces 11 to 14, for example. These room temperature sensors 25 correspond to temperature acquisition means.

  Each of the air-conditioned spaces 11 to 14 is provided with a human detection sensor 26 as human detection means. The human detection sensor 26 is a sensor that detects that there is a person in the air-conditioned spaces 11 to 14 in which the sensor 26 is provided. The human detection sensor 26 is provided, for example, on the ceiling of the air-conditioned spaces 11-14.

  Next, the electrical configuration of the air conditioning system will be described with reference to FIG. FIG. 2 is a diagram showing an electrical configuration of the air conditioning system.

  As shown in FIG. 2, the air conditioning system includes an air conditioning controller 30 as control means. The air conditioner controller 30 controls the operation of the air conditioner 21 and includes a known microcomputer having a CPU and the like. The air conditioning controller 30 is built in the air conditioner 21, for example.

  An operation device 31 (remote control device) is connected to the air conditioning controller 30. The operation device 31 performs various operations related to the operation of the air conditioner 21, and is provided on the wall surface of the living room 11, for example. The operation device 31 includes an ON / OFF switch for executing (ON) or stopping (OFF) the operation of the air conditioner 21, a changeover switch for switching between the cooling operation or the heating operation of the air conditioner 21, and the air conditioner. A temperature setting button or the like for setting the cooling set temperature or the heating set temperature of 21 is provided. When the operation device 31 is operated by the switch or the like, a signal corresponding to the operation is input to the air conditioning controller 30. The air conditioning controller 30 controls the operation of the air conditioner 21 based on the input operation signal. For example, when the cooling set temperature or the heating set temperature of the air conditioner 21 is input, the air conditioning controller 30 sets the input set temperature as a target temperature (that is, the temperature of the air-conditioned spaces 11 to 14 becomes the set temperature). ), The cooling operation or heating operation of the air conditioner 21 is controlled.

  The air conditioning controller 30 has an automatic operation mode and an automatic operation prohibition mode as control modes (operation stop mode) when the operation of the air conditioner 21 is stopped. The automatic operation mode is a mode for automatically starting the operation of the air conditioner 21 when the temperature (room temperature) of the air conditioned spaces 11 to 14 is significantly increased or decreased when the operation of the air conditioner 21 is stopped. The air conditioning controller 30 starts the cooling operation of the air conditioner 21 when the room temperature of the air conditioned spaces 11 to 14 is remarkably increased when the automatic operation mode is set, and when the room temperature of the air conditioned spaces 11 to 14 is remarkably decreased. Starts the heating operation of the air conditioner 21. On the other hand, the automatic operation prohibition mode is a mode for prohibiting the operation of the air conditioner 21 from being started even when the room temperature of the air conditioned spaces 11 to 14 is significantly increased or decreased when the operation of the air conditioner 21 is stopped.

  In the present air conditioning system, the operation stop mode of the air conditioner 21 can be switched between the automatic operation mode and the automatic operation inhibition mode based on the operation of the operation device 31. When switching to one of the modes is performed by operating the operation device 31, the air conditioning controller 30 sets the mode corresponding to the switching operation as the operation stop time mode.

  Each room temperature sensor 25 and each person detection sensor 26 are connected to the air conditioning controller 30. The air conditioning controller 30 receives detection signals from these sensors 25 and 26 sequentially. When the operation of the air conditioner 21 is stopped, the air conditioner controller 30 operates the air conditioner 21 based on the detection signals from these sensors 25 and 26 and the operation stop time mode set in the controller 30. Start operation control to be started.

  Next, the air conditioning control process executed by the air conditioning controller 30 will be described with reference to the flowchart shown in FIG. This process is repeatedly executed at a predetermined cycle.

  As shown in FIG. 3, first, in step S11, it is determined whether or not the operation of the air conditioner 21 is being executed. That is, it is determined whether the cooling operation or the heating operation of the air conditioner 21 is being executed. When the operation of the air conditioner 21 is stopped, the process proceeds to step S14, and when the operation of the air conditioner 21 is being performed, the process proceeds to step S12.

  In step S12, it is determined whether or not an OFF operation for stopping the operation of the air conditioner 21 has been performed by the operation device 31 (ON / OFF switch). This determination is made based on whether or not an OFF signal is input from the controller device 31. If the OFF operation has not been performed, this process ends. If the OFF operation has been performed, the process proceeds to step S13.

  In step S13, the operation (cooling operation or heating operation) of the air conditioner 21 is stopped by outputting an operation stop signal to the air conditioner 21. Thereby, cooling or heating of each air-conditioned space 11-14 by the air conditioner 21 is stopped.

  The process after step S14 is an operation stop process performed when the air conditioner 21 is stopped. In the operation stop process, first, in step S14, it is determined based on the detection signal from each person detection sensor 26 whether or not the resident is at home in the building 10 (corresponding to a home determination means). When the presence of a person is detected by any one of the person detection sensors 26, it is determined that the resident is at home and the process proceeds to step S15. On the other hand, if the presence of a person is not detected by any of the person detection sensors 26, it is determined that the resident is not at home, and this process is terminated.

  In step S15, the room temperature of each air-conditioned space 11-14 is acquired based on the detection signal from each room temperature sensor 25. In a succeeding step S16, it is determined whether the air conditioner 21 is set to the cooling operation setting or the heating operation setting. This determination is performed based on the cooling / heating setting by the changeover switch of the operation device 31. If the air conditioner 21 is set to air cooling, the process proceeds to step S17.

  In step S17, it is determined which of the automatic operation mode and the automatic operation prohibition mode is set as the control mode (operation stop mode) when the operation of the air conditioner 21 is stopped. If the automatic operation mode is set, the process proceeds to step S18, and it is determined whether any one of the air-conditioning spaces 11 to 14 acquired in step S15 is equal to or higher than a predetermined cooling start temperature Tc1. judge. That is, here, it is determined whether or not any of the above room temperatures has increased to the cooling start temperature Tc1 (has reached the cooling start temperature Tc1). In this case, the cooling start temperature Tc1 is set to a temperature that may cause heat stroke or the like when staying in the air-conditioned spaces 11 to 14 in the temperature environment, and is set to 35 ° C., for example. The cooling start temperature Tc1 corresponds to the “predetermined temperature” and the “first temperature”. When the room temperature of each of the air-conditioned spaces 11-14 is lower than the cooling start temperature Tc1, the present process is terminated, and any one of the room temperatures of the air-conditioned spaces 11-14 is equal to or higher than the cooling start temperature Tc1. If YES, the process proceeds to step S19.

  In step S19, the cooling operation start signal is output to the air conditioner 21 to start (execute) the cooling operation of the air conditioner 21. Thereby, the cooling of the air-conditioned spaces 11 to 14 by the air conditioner 21 is started. Accordingly, when the room temperature of the air-conditioned spaces 11 to 14 is remarkably increased when the air-conditioning apparatus 21 stops the cooling operation, the air-conditioning apparatus 21 is automatically started to perform the cooling operation. Thereafter, this process is terminated.

  In step S17, when the automatic operation prohibition mode is set, the process proceeds to step S21, in which one of the room temperatures of the air-conditioned spaces 11 to 14 is equal to or higher than a predetermined cooling start temperature Tc2. Determine. That is, here, it is determined whether or not any of the above room temperatures has increased to the cooling start temperature Tc2 (has reached the cooling start temperature Tc2). In this case, the cooling start temperature Tc2 is set to a temperature higher than the cooling start temperature Tc1 (Tc2> Tc1), and is set to 40 ° C., for example. In other words, the cooling start temperature Tc2 is a temperature that deviates (largely) from the cooling set temperature Tc0 of the air conditioner 21 than the cooling start temperature Tc1, that is, Tc2-Tc0> Tc1-Tc0. Yes. The cooling start temperature Tc2 corresponds to the “second temperature”.

  When the room temperature of each of the air-conditioned spaces 11 to 14 is lower than the cooling start temperature Tc2, this process ends. On the other hand, when any one of the room temperatures of the air-conditioned spaces 11 to 14 is equal to or higher than the cooling start temperature Tc2, the process proceeds to step S19, and the cooling operation of the air conditioner 21 is started. Thereafter, this process is terminated. Thereby, even when the automatic operation prohibition mode is set, the cooling operation of the air conditioner 21 is started when the room temperature of the air-conditioned spaces 11 to 14 is further remarkably increased.

  In step S16 described above, if the air conditioner 21 is set to heating, the process proceeds to step S23, and it is determined which mode is set as the operation stop time mode among the automatic operation mode and the automatic operation inhibition mode. . When the automatic operation mode is set, the process proceeds to step S24, and it is determined whether any one of the room temperatures of the air-conditioned spaces 11 to 14 is equal to or lower than a predetermined heating start temperature Th1. That is, here, it is determined whether or not any of the above room temperatures has decreased to the heating start temperature Th1 (whether it has reached the heating start temperature Th1). In this case, the heating start temperature Th1 is set to a temperature that may cause a cold or the like when staying in the air-conditioned spaces 11 to 14 in the temperature environment, and is set to 8 ° C., for example. The heating start temperature Th1 corresponds to a “predetermined temperature” and a “first temperature”. When the room temperature of each air-conditioned space 11-14 is higher than the heating start temperature Th1, this process is terminated, and one of the room temperatures of each air-conditioned space 11-14 is equal to or lower than the heating start temperature Th1. If YES, the process proceeds to step S25.

  In step S25, the heating operation start signal is output to the air conditioner 21 to start (execute) the heating operation of the air conditioner 21. Thereby, heating of the air-conditioned spaces 11 to 14 by the air conditioner 21 is started. Accordingly, when the room temperature of the air-conditioned spaces 11 to 14 is remarkably lowered when the heating operation of the air conditioner 21 is stopped, the heating operation of the air conditioner 21 is automatically started. Thereafter, this process is terminated.

  In step S23, when the automatic operation prohibition mode is set, the process proceeds to step S26, and whether any one of the room temperatures of the air-conditioned spaces 11 to 14 is equal to or lower than a predetermined heating start temperature Th2. Determine. That is, here, it is determined whether or not any of the above room temperatures has decreased to the heating start temperature Th2 (has reached the heating start temperature Th2). In this case, the heating start temperature Th2 is set to a temperature lower than the heating start temperature Th1 (Th1> Th2), and is set to 3 ° C., for example. In other words, the heating start temperature Th2 is a temperature that deviates (largely) from the heating set temperature Th0 of the air conditioner 21 than the heating start temperature Th1, that is, Th0−Th2> Th0−Th1. Yes. The heating start temperature Th2 corresponds to the “second temperature”.

  When the room temperature of each of the air-conditioned spaces 11 to 14 is higher than the heating start temperature Th2, this process is terminated. On the other hand, when any one of the room temperatures of the air-conditioned spaces 11 to 14 is equal to or lower than the heating start temperature Th2, the process proceeds to step S25, and the heating operation of the air conditioner 21 is started. Thereafter, this process is terminated. Thereby, even when the automatic operation prohibition mode is set, the heating operation of the air conditioner 21 is started when the room temperature of the air-conditioned spaces 11 to 14 is further remarkably lowered.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  When the operation of the air conditioner 21 is stopped based on the OFF operation (operation stop operation) of the operation device 31 (ON / OFF switch) by the resident, the room temperature of each of the air conditioned spaces 11 to 14 is acquired and acquired. When any one of the room temperatures of the air-conditioned spaces 11 to 14 rises to the first cooling start temperature Tc1, the cooling operation of the air conditioner 21 is started, and any one of the room temperatures starts the first heating. When the temperature drops to Th1, the heating operation of the air conditioner 21 is started. Thereby, when the room temperature of the air-conditioned spaces 11 to 14 is remarkably increased when the cooling operation is stopped in summer, the cooling operation is automatically started, and when the heating operation is stopped in winter, the air-conditioned space 11 is stopped. When the room temperature of -14 falls remarkably, heating operation can be started automatically. Thereby, even when a resident (grandparent) does not notice that the room temperature of the air-conditioned spaces 11 to 14 has increased or decreased when the operation of the air-conditioning apparatus 21 is stopped, the operation of the air-conditioning apparatus 21 can be automatically resumed. Therefore, it is possible to prevent the resident (grandparent) from deteriorating his / her physical condition due to the temperature rise or temperature drop of the air-conditioned spaces 11 to 14 due to the suspension of the operation of the air conditioner 21.

  When the automatic operation inhibition mode is set, the cooling operation of the air conditioner 21 is not started even if the room temperature of the air-conditioned spaces 11 to 14 rises to the cooling start temperature Tc1. When the automatic operation prohibition mode is set, the heating operation of the air conditioner 21 is not started even if the room temperature of the air-conditioned spaces 11 to 14 is lowered to the heating start temperature Th1. Thereby, when the resident (for example, grandparents) is not good at air conditioning due to cold, etc., the operation of the air conditioner 21 can be prevented from starting. It can be prevented from feeling.

  Even when the automatic operation prohibition mode is set, if any one of the air-conditioning spaces 11 to 14 rises to the second cooling start temperature Tc2 higher than the first cooling start temperature Tc1, the air conditioner 21 cooling operation was started. Even when the automatic operation prohibition mode is set, the heating operation of the air conditioner 21 is started when any one of the above room temperatures decreases to the second heating start temperature Th2 lower than the first heating start temperature Th1. I did it. Thereby, even when the resident who is not good at air conditioning (for example, grandparents) is set in the automatic operation prohibition mode, the operation of the air conditioner 21 is automatically performed when the temperature of the air-conditioned spaces 11 to 14 is further significantly increased or decreased. In this case, the resident can be prevented from getting sick.

  When it is determined that the resident is at home in the building 10, the operation of the air conditioner 21 is started. In this case, since the operation of the air conditioner 21 is not started when the resident is not at home, it is possible to avoid operating the air conditioner 21 wastefully even though the resident is absent. .

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the cooling operation of the air conditioner 21 is automatically started when the room temperature of the air conditioned spaces 11 to 14 rises to the cooling start temperature Tc1 when the cooling operation of the air conditioner 21 is stopped. And when the room temperature of the air-conditioned spaces 11 to 14 rises to the cooling start temperature Tc1, a notification process for urging the occupant to start the cooling operation of the air conditioner 21 may be performed. For example, it is conceivable to perform a notification process by providing a notification device such as a buzzer or a speaker in the building 10 and outputting sound by the notification device. Moreover, you may perform an alerting | reporting process by transmitting mail to portable terminals, such as a smart phone which a resident carries. Even in such a case, it is possible to make the occupant notice that the room temperature of the air-conditioned spaces 11 to 14 has significantly increased, and to allow the occupant to resume the cooling operation of the air conditioner 21. Similarly to this, when the room temperature of the air-conditioned spaces 11 to 14 is lowered to the heating start temperature Th1 when the heating operation of the air conditioner 21 is stopped, a notification process for prompting the heating operation start operation of the air conditioner 21 may be performed. Also in this case, it is possible to make the occupant notice that the room temperature of the air-conditioned spaces 11 to 14 has significantly decreased, and to allow the occupant to resume the heating operation of the air conditioner 21. Therefore, also in this case, it is possible to prevent the resident (for example, grandparents) from getting sick due to the temperature rise or temperature drop of the air-conditioned spaces 11 to 14 due to the suspension of the operation of the air conditioner 21.

  (2) In the configuration of performing the notification process described in (1) above, when the operation of the air conditioner 21 is not started even after a predetermined time has elapsed since the notification process was performed, the air conditioner controller 30 You may make it perform control which starts a driving | operation automatically. When a resident (for example, grandparents) is taking a nap or the like, it is assumed that the resident is not aware of it even if the notification process is performed. In that respect, if it is set as the said structure, since the driving | operation of the air conditioner 21 is started automatically in such a case, it can prevent that a resident | setter's physical condition worsens.

  (3) In the above embodiment, when any one of the air-conditioning spaces 11 to 14 reaches the cooling start temperature Tc2 or the heating start temperature Th1 when the automatic operation prohibit mode is set, the air conditioner 21 is operated. However, it may be changed so that the operation of the air conditioner 21 is not started.

  (4) For example, when any one of the room temperatures of the air-conditioned spaces 11 to 14 rises to the cooling start temperature Tc1 or falls to the heating start temperature Th1, the air conditioning controller 30 causes the rise or fall from It may be determined whether or not the elapsed time has exceeded a predetermined time, and if the result of the determination is that the predetermined time has been exceeded, a cooling operation or a heating operation of the air conditioner 21 may be started.

  (5) In the above embodiment, the air conditioner 21 has the cooling function and the heating function. However, the air conditioner 21 may have only the cooling function or only the heating function. Therefore, the present invention may be applied to such an air conditioner 21.

  (6) Since the living room 11 is a relatively large room among the air-conditioned spaces 11 to 14, a plurality of room temperature sensors 25 may be arranged in the living room 11. In this case, for example, it is conceivable to obtain the average value of the room temperature detected by each room temperature sensor 25 as the room temperature of the living room 11. By doing so, it is possible to cope with a case where a temperature difference occurs in the living room 11.

  (7) As a whole-building air conditioning system, in a multi-storey building, a configuration in which air conditioning of each floor portion is performed by a common air conditioner is conceivable. For example, in a two-story building, a configuration may be considered in which the first floor space (first floor space) and the second floor space (second floor space) are air-conditioned by a common air conditioner. When the present invention is applied to such an air conditioning system, a room temperature sensor is provided in each floor space.
