Total heat exchanger 40 and the air conditioner 60, the humidifier 10 in cooperation with an indoor based on humidity information, temperature information, CO ₂ amount information from the CO ₂ sensor from the temperature sensor 63 from the humidity sensor 20A, 20B Air conditioning control is performed.

  FIG. 2 shows a schematic configuration of the humidification control system 1 in the present embodiment. In the humidification control system 1, the humidifier 10 receives a command from the controller 30 and humidifies the room via the duct DT. The humidity sensors 20 </ b> A and 20 </ b> B measure indoor humidity and transmit the measured value to the controller 30 via the communication line 2.

In addition, in this embodiment, the humidifier 10 is installed for every tenant division, and the example which further partitions the room | chamber interior by partition PT is given.

<Schematic configuration of humidification control unit>
FIG. 3 shows the configuration of the humidification control system 1 and the flow of each information. The controller 20 includes a humidification control unit 11 and a reference setting unit 13, and the humidifier 10 includes a humidification execution unit 12. The humidification control unit 11 includes a capability control unit 11a that controls the humidification capability of the humidifier 10 (for example, setting the humidification capability to be strong or weak), and a start / stop control unit 11b that controls the start / stop of the operation of the humidifier 10. including. The humidifying execution unit 12 executes or stops humidification in response to a command from the capacity control unit 11a or the start / stop control unit 11b. The reference setting unit 13 receives and holds one or more pieces of reference information input by a predetermined input unit in the management device 50 and sets one of the references.

  The reference information is reference information for obtaining a humidity determination value that is a determination reference for humidification control from the measured values of the humidity sensors 20A and 20B. Specifically, the measurement value of any one of the humidity sensors 20A and 20B that is designated in advance (the reference for selecting the higher one among the measurement values of the humidity sensors 20A and 20B (hereinafter referred to as the automatic reference) or the humidity sensor 20A and 20B). Is a reference for the humidity determination value (hereinafter referred to as a fixed reference). The automatic reference and the fixed reference may be set so as to be switchable according to the time and the indoor use state.

  Further, the humidification control unit 11 receives the set temperature of the indoor unit 62, the presence / absence of a humidification permission signal, and the start / stop command of the indoor unit 62 from the management device 50, and also receives the humidity measurement values from the humidity sensors 20A and 20B. .

For example, the measurement may be performed at short time intervals when the humidifier 10 is operating, and may be measured at long time intervals when the humidifier 10 is stopped.

  Based on these information, humidification control is performed in the procedure described later. Further, as will be described later, a humidity upper and lower limit margin set in advance to give a hysteresis to the condition determination of the humidification control operation is received from the management device 50. The upper and lower limit margins may be parameterized and changed via the management device 50.

<Processing flow of humidification control system according to this embodiment>
The process flow of the humidification control system 1 will be described with reference to the flowcharts of FIGS. 4 and 5.

  First, as shown in FIG. 4, the humidification control unit 11 determines whether or not a fixed reference is set in the reference setting unit 13 (step S101). If the fixed reference is set, it is further determined whether or not the humidity sensor 20A is fixed (step S102). When it is fixed to 20A, the measurement value of 20A is acquired (step S104), and when it is not fixed to 20A, that is, when it is fixed to 20B, the measurement value of 20B is acquired (step S105).

  On the other hand, when the fixed reference is not set, that is, when the automatic reference is set, the measured value of the humidity sensor 20A is compared with the measured value of the humidity sensor 20B (step S103), and the measured value of 20A is 20B. If this is the case, a measurement value of 20A is acquired (step S104). When the measured value of 20A is less than 20B, the measured value of 20B is acquired (step S105).

  Next, as shown in FIG. 5, the humidification control unit 11 determines whether or not a humidification permission signal is received (step S106). If the humidification permission signal has not been received, a humidification stop command is issued (step S114). When the humidification permission signal is received, it is determined whether any of the indoor units is in operation (step S107). If not in operation, a humidification stop command is issued (step S114).

  In step S107, if any of the indoor units is in operation, it is further determined whether or not the measurement value acquired in step S104 or step S105 is less than the set humidity (step S108). If it is less than the set humidity, it is determined whether or not the measured value exceeds the set humidity-lower limit margin value (step S109). On the other hand, if the measured value is equal to or higher than the set humidity, it is determined whether or not the measured value is equal to or lower than the set humidity + the upper limit margin value (step S110).

  In step S109, when the measured value exceeds the set humidity-lower limit margin value, a humidifying operation command and a command for setting the humidifying capability to “weak” or “strong” are issued (step S111). If the measured value is less than or equal to the set humidity-lower limit margin value, a humidifying operation command and a command for setting the humidifying capability to "strong" are issued (step S112).

  In step S110, if the measured value is equal to or less than the set humidity + the upper limit margin, a humidifying operation command and a command for setting the humidifying capacity to “weak” or a stop command is issued (step S113). If the measured value exceeds the value of set humidity + upper limit margin, a humidification stop command is issued (step S114).

  FIG. 6 is a graph showing the control operation by the above processing. As shown in the figure, by giving a certain hysteresis to the condition determination of the control operation, hunting or the like can be prevented when the measured humidity changes abruptly.

  Specifically, the humidity judgment value has an upper limit margin and a lower limit margin, and for the measurement value within the margin range, the next operation operation is performed according to the current operation operation of the humidifier 10. Is determined. That is, when the measured value is less than the set humidity and exceeds the set humidity-lower limit margin value (steps S108 to S109 in FIG. 5), the humidifier 10 is currently stopped or in operation and the humidification capacity is “weak”. In the case of “”, a command to make the humidification capacity “weak” is issued (step S111). On the other hand, if the humidifier 10 is currently in operation and the humidifying capacity is “strong”, a command to make the same humidifying capacity “strong” is issued (step S111), and the state is maintained.

  When the measured value is equal to or higher than the set humidity and equal to or lower than the set humidity + the upper limit margin (steps S108 and S110 in FIG. 5), the humidifier 10 is in operation and the humidification capability is “strong” or “ If it is in the “weak” state, a command to make the humidification capacity “weak” is issued (step S113). On the other hand, when the humidifier 10 is stopped, a humidification stop command is issued (step S113), and the state is maintained.

  As described above, by giving a certain hysteresis to the determination condition of the control operation, it is possible to prevent hunting or the like even when the measured humidity changes abruptly.

<Characteristics of the air conditioning control system according to this embodiment>

In the humidification control system 1 according to the present embodiment, the humidification control unit 11 determines a humidity determination value according to the reference set in the reference setting unit 13, and based on the humidity determination value, humidification operation, humidification stop, humidification capability Since the control is performed, appropriate humidity control can be performed even in a room with uneven humidity due to various usage conditions.

(2)
In the humidification control system 1 according to the present embodiment, the reference setting unit 13 includes an automatic reference in which the higher or lower of the measured values of the humidity sensors 20A and 20B is a humidity determination value, and the humidity sensors 20A and 20B. Set a second standard that uses the humidity sensor's measured value as one of the humidity sensors specified in advance, and perform humidification control according to these standards, so you want to avoid humidity or to ensure sufficient humidity In some cases, appropriate humidity control can be performed. Moreover, since these standards can be switched according to time or the like, it is possible to perform appropriate humidity control according to not only the use state but also time.

(3)
In the humidification control system 1 according to the present embodiment, when the humidification control unit 11 issues a humidification operation command, the humidification control unit 11 also performs humidification capability control, so that appropriate humidity control according to any situation can be performed. In addition, when controlling the humidifying capacity, it is possible to provide an upper / lower limit margin for the humidity determination value and to add hysteresis to the condition determination, so that it is possible to cope with a sudden humidity change.

<Modification>
(A)
In the above embodiment, the number of sensors is two for one humidifier, but three or more sensors may be received. In this case, the reference setting unit 13 sets another reference that excludes any of the humidity sensors specified in advance among the three or more humidity sensors, and the humidification control unit 11 removes the humidity sensor that is excluded according to the third reference. Humidity control may be performed using a measured value of a humidity sensor other than as a humidity determination value. Thereby, for example, even when the humidity sensor is located in a place inappropriate for humidity measurement (for example, on a water heater), appropriate humidification control can be performed. Further, this other reference may be switchable between the automatic reference and the fixed reference in the above embodiment.

(B)
In the above embodiment, the fixed reference set in the reference setting unit 13 may be a humidity determination value that is a measurement value of a humidity sensor set in the vicinity of the indoor unit 62 during operation. Since there is a high possibility that there are many people near the indoor unit 62 during operation, more effective humidification control can be realized. Further, in order to perform more accurate humidification control, the measured value of the sensor away from the outlet of the duct DT may be used as the humidity determination value.

(C)
In the above embodiment, the automatic reference set in the reference setting unit 13 uses the higher one of the measured values of the humidity sensors 20A and 20B as the humidity determination value, but may be the lower one. Or you may enable it to switch a high side and a low side according to time. For example, in order to prevent drying in the daytime, the lower measurement value is acquired, and in the night, the higher measurement value is acquired. Thereby, more precise humidity control can be performed.
