In the related art, most air conditioners only adjust the operation frequency of the air conditioner, and it is difficult to operate the air conditioner in the optimal state at each stage of the operation of the air conditioner by only adjusting the operation frequency, the energy consumption at each stage is difficult to be reduced to the minimum, and the comfort experience of users is difficult to be improved to the optimal state.
In order to solve the problems mentioned in the background art, according to an aspect of an embodiment of the present application, an embodiment of an air supply control method is provided.
Alternatively, in the embodiment of the present application, the above-described air flow control method may be applied to a hardware environment constituted by the terminal 101 and the server 103 as shown in fig. 1. As shown in fig. 1, a server 103 is connected to a terminal 101 through a network, which may be used to provide services for the terminal or a client installed on the terminal, and a database 105 may be provided on the server or separately from the server, and is used to provide data storage services for the server 103, and the network includes but is not limited to: wide area network, metropolitan area network, or local area network, the terminal 101 includes but is not limited to an air conditioner, a PC, a mobile phone, a tablet computer, etc.
An air supply control method in the embodiment of the present application may be executed by the server 103, or may be executed by both the server 103 and the terminal 101, as shown in fig. 2, the method may include the following steps:
step S202, first detection data and second detection data are obtained, wherein the first detection data are obtained by detecting a target space where the air conditioner is located, and the second detection data are obtained by detecting the air conditioner.
In the embodiment of the application, the air conditioner can be divided into an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit carry out heat transfer to realize refrigeration or heating of a room. The target space may be an indoor space where the indoor unit is located, or may be an outdoor space where the outdoor unit is located. The detected data may be temperature, and accordingly, the first detected data includes indoor temperature and outdoor temperature. The second detection data is used for detecting the air conditioner, and preferably, only data of the indoor unit, such as the air supply temperature of the air outlet and the temperature of the inner pipe of the air conditioner, is detected, and the operating frequency of the air conditioner can also be detected.
In the embodiment of the present application, the load of the air conditioner may be indirectly represented by a difference between the current indoor temperature and the temperature set by the user, for example, the current indoor temperature is 30 degrees, in one case, the temperature set by the user is 24 degrees, in another case, the temperature set by the user is 26 degrees, and then the operation load of the air conditioner when the indoor temperature is reduced from the current 30 degrees to 24 degrees is greater than the operation load when the indoor temperature is reduced from the current 30 degrees to 26 degrees.
And step S204, determining the target air supply volume of the air conditioner according to the incidence relation between the first detection data and the preset reference data.
In the embodiment of the application, the relation of each level of the indoor temperature and the temperature set by the user can be preset to represent the operation load of the air conditioner, the matched air supply volume is set for the relation of each level (the operation load of different degrees), the indoor and outdoor temperature difference can also be used as the characteristic of the operation load of the air conditioner, the multistage relation of the indoor and outdoor temperature difference can be set to represent the operation load of the air conditioner, and the matched air supply volume is set for the relation of each level (the operation load of different degrees). The air supply volume can be represented by a windshield, for example, the first gear is a gear with the minimum air supply volume, the second gear is a gear with the moderate air supply volume, and the third gear is a gear with the maximum air supply volume, or the air supply volume can be adjusted in a stepless manner.
In the embodiment of the application, the method for determining the wind gear comprises the steps of starting time and operation process.
At the starting time, the heat dissipation of the air-conditioning enclosure structure can be determined according to the indoor and outdoor temperature difference, in addition, the required cold quantity or heat quantity reaching the temperature set by the user can be determined according to the temperature difference between the indoor environment temperature and the temperature set by the user, and the cold quantity or the heat quantity and the initial operation wind gear are determined by the cold quantity or the heat quantity and the initial operation wind gear together.
During the operation of the air conditioner, the current indoor temperature rise/temperature drop condition can be known according to the change rate of the indoor environment temperature, the cold or heat required by a room is judged, meanwhile, the outlet air temperature changes during the operation, and the current operation air gear can be determined according to the current outlet air temperature and the cold/heat required by the room.
And step S206, determining a target air supply angle of the air conditioner by using the second detection data and the target air supply volume.
In the embodiment of the application, in order to make the indoor temperature change uniform and improve the user comfort experience, the air supply angle of the air conditioner can be determined according to the second detection data and the air supply volume of the air conditioner, for example, when the air conditioner is used for heating, hot air density is different due to different air supply temperatures, and the trend of hot air floating is different. If the hot air floating phenomenon can not be inhibited, a large amount of heat is gathered on the roof and cannot be effectively utilized, and finally the temperature of a room is not uniformly increased, so that the air supply angle can be adjusted according to the real-time air supply temperature and the air supply air volume of the air conditioner, the hot air floating phenomenon with different densities is inhibited, the heat is fully utilized, the indoor temperature is uniformly increased, and the comfort level experience of a user is improved.
And S208, controlling air supply of the air conditioner according to the target air supply volume and the target air supply angle.
In the embodiment of the present application, time-order cooperative control may be performed, taking low-temperature heating as an example: in the early stage of operation, the air conditioner is judged to be low in room temperature and large in required heating capacity, the air conditioner is operated at a large wind gear and a high air outlet temperature, and according to an air supply jet flow trajectory formula, in order to ensure that the hot air coverage is wider, the upward floating of hot air is reduced, and therefore the downward inclination angle of air supply is increased. The supply air jet trajectory formula may be expressed as:
in the formula, T0For supply air temperature, TrIs indoor temperature, x and y are track coordinates, alpha is air supply inclination angle, ArIs an Archimedes number, A0Is the effective area of the air supply of the air outlet of the air conditioner, wherein, the Archimedes number ArComprises the following steps:
in the formula of U0Is the blast air volume (i.e. windshield or wind speed). As can be seen from the above formula, the air supply temperature, the air supply speed (or air supply amount, wind level), and the indoor environment temperature determine the trajectory (including the landing distance and the air supply distance) of the high-temperature jet flow. When the air supply temperature, the wind shield and the indoor environment temperature are different in refrigeration or heating, the optimal air supply angle is correspondingly formed.
Because the air conditioner keeps a constant large wind gear in the early stage of operation, but the air outlet temperature of the air conditioner gradually rises along with the rising of the frequency until the temperature is stable, and the optimal air supply angle also changes according to an air supply jet flow track formula. Therefore, in the early stage of operation, the air conditioner operates in a constant and constant large wind gear, the air outlet temperature gradually rises, and the downward inclination angle of the air outlet also changes from small to large along with the air outlet temperature range until the air outlet temperature does not change.
When the room temperature is higher and tends to be stable, the heat supply amount needed by the room is reduced, the variable frequency air conditioner operates in a frequency reduction mode, the air outlet temperature begins to be reduced at the moment, and the air conditioner reduces the wind gear according to the heat required by the room at present. After the wind shield is reduced, the air outlet temperature is increased, and the downdip angle of the air supply is changed along with the change of the air supply jet flow trajectory formula. In the frequency reduction operation stage of the air conditioner, the air outlet air gear and the air outlet temperature are simultaneously controlled according to the method, so that the thermal comfort of a room can be maintained under the condition that the air conditioner does not stop, and the air conditioner can operate in an energy-saving manner.
By adopting the technical scheme, the air supply quantity and the air supply angle can be changed according to parameters such as the indoor temperature, the outdoor temperature, the air supply temperature of the air conditioner, the temperature of the inner pipe of the air conditioner, the running frequency of the air conditioner and the like in different stages, so that the air conditioner runs in the best state in each stage, the energy consumption is reduced to the maximum extent, and the comfort level experience of a user is improved.
Alternatively, as shown in fig. 3, determining the target air supply volume of the air conditioner according to the association relationship between the first detection data and the preset reference data may include the following steps:
step S302, a first temperature difference value between a first temperature value and a set temperature value is obtained, the first temperature value is the temperature of a first space where a first air conditioner is located, first detection data comprises the first temperature value, preset reference data comprises the set temperature value, and a target space comprises the first space;
step S304, determining a first target interval in which the first temperature difference value is located;
and step S306, determining the target air supply volume matched with the first target interval.
In the embodiment of the application, the first temperature value is a current indoor temperature value, the first space is an indoor space where the indoor unit is located, a difference value between the current indoor temperature value and a temperature value set by a user can indicate an operation load of the air conditioner for adjusting the indoor temperature to a temperature set by the user next time, if the difference value is large, the operation load of the air conditioner is large, otherwise, the operation load is small, and the air supply volume can be determined according to the operation loads of different degrees.
