In the apparatus shown in fig. 1, the processor 1001 may be configured to call an air conditioning temperature and humidity control program stored in the memory 1002, and perform operations of relevant steps of the air conditioning temperature and humidity control method in the following embodiments.
The embodiment of the invention also provides a temperature and humidity control method which is applied to the air conditioner.
Referring to fig. 2, an embodiment of a temperature and humidity control method according to the present application is provided. In this embodiment, the temperature and humidity control method includes:
step S10, controlling a heating module to heat air in an air outlet duct of the air conditioner, and controlling the dehumidification operation of the air conditioner according to set dehumidification parameters, wherein the reduction range of the indoor environment temperature is smaller than or equal to a set threshold when the air conditioner operates according to the set dehumidification parameters;
specifically, step S10 is performed in the settable dehumidification mode. The setting of the dehumidification mode specifically refers to an operation mode of the air conditioner that reduces the humidity of the indoor environment while not reducing the temperature of the indoor environment. The indoor heat exchanger is in an evaporation state under the set dehumidification mode, and the air passing through the indoor heat exchanger is reduced in humidity compared with the air passing through the indoor heat exchanger, so that dehumidification is realized. Specifically, the set dehumidification mode can be entered when a control instruction input by a user is received; in addition, the temperature and humidity of the current indoor environment can be monitored by the air conditioner, the air conditioner is controlled to enter a set dehumidification mode when the monitored data meet preset conditions, and for example, the air conditioner is controlled to enter the set dehumidification mode when the indoor environment temperature is lower than the set environment temperature and the indoor environment humidity is higher than or equal to the set humidity.
In the embodiment of the invention, the heating module is specifically an electric auxiliary thermal module, which can be an electric auxiliary thermal module with adjustable heating power or an electric auxiliary thermal module with nonadjustable heating power. When the heating module heats the air in the air outlet duct, the heating module can operate at variable heating power and also can operate at fixed heating power.
The dehumidification parameters are set in advance, so that the reduction range of the indoor environment temperature is smaller than or equal to a set threshold value. Specifically, the air of the indoor environment enters the air conditioner and exchanges heat with the indoor heat exchanger for dehumidification, the temperature before the air exchanges heat with the indoor heat exchanger is defined as a first temperature, the temperature after the air exchanges heat with the indoor heat exchanger is defined as a second temperature, and the falling amplitude of the air of the indoor environment refers to the temperature deviation between the first temperature and the second temperature.
The set dehumidification parameters can comprise one or more than one operation parameters of components related to the output cold quantity in the dehumidification process of the air conditioner, and can be specifically selected according to actual conditions, and the output cold quantity of the air conditioner can be less than or equal to a set threshold value only by ensuring that the air conditioner operates according to the set dehumidification parameters. The size of the set threshold may be determined according to actual conditions.
When the air conditioner operates according to the set dehumidification parameters, the heat emitted when the heating module is opened can compensate the heat absorbed when the air conditioner performs refrigeration and dehumidification, so that the air outlet temperature of the air conditioner is not too low.
And step S20, adjusting the dehumidification operation parameters of the air conditioner to ensure that the air outlet temperature of the air conditioner is greater than or equal to the air inlet temperature of the air conditioner.
The inlet air temperature is characterized by the temperature of air which enters the air conditioner in the indoor environment and is not subjected to temperature and humidity regulation; the outlet air temperature is characterized in that the temperature of the air entering the air conditioner is regulated and controlled by the temperature and the humidity and then is sent to the indoor environment.
The air outlet temperature can be obtained by acquiring data detected by a temperature sensor arranged at an air outlet of the air conditioner. The inlet air temperature can be obtained by acquiring data detected by a temperature sensor arranged at an air return inlet of the air conditioner.
Here, the dehumidification operation parameter specifically refers to an operation parameter of a component related to the outlet air temperature during the current dehumidification operation of the air conditioner.
Different air outlet temperatures and air inlet temperatures correspond to different adjustment parameters corresponding to the dehumidification operation parameters. The adjustment parameters may specifically include an adjustment direction (such as increasing, decreasing, or maintaining unchanged), an adjustment amplitude, an adjustment proportion, an adjustment rate, and the like of the dehumidification operation parameters. The corresponding relation between the air outlet temperature, the air inlet temperature and the adjustment parameters of the dehumidification operation parameters can be preset, and can be a quantity relation, a mapping relation and the like. Based on the corresponding relation, the adjustment parameters of the dehumidification operation parameters corresponding to the current air outlet temperature and the current air inlet temperature can be determined, and the dehumidification operation parameters of the air conditioner can be adjusted based on the determined adjustment parameters. Under the same air outlet temperature and air inlet temperature, the corresponding adjustment parameters are different when the types of the dehumidification operation parameters are different, and the air outlet temperature after the dehumidification operation parameters are adjusted is only required to be closer to a target interval compared with the current air outlet temperature, and the target interval is a temperature set larger than or equal to the air inlet temperature.
Specifically, the corresponding adjustment parameters may be determined to adjust the dehumidification operation parameters of the air conditioner based on a quantitative relationship (e.g., temperature deviation, temperature ratio, etc.) between the outlet air temperature and the inlet air temperature, a magnitude relationship (e.g., outlet air temperature greater than or equal to inlet air temperature and outlet air temperature less than inlet air temperature) between the outlet air temperature and the inlet air temperature, and the like. Different temperature deviations correspond to different adjustment ranges or adjustment proportions, and different size relationships correspond to different adjustment directions. For example, when the outlet air temperature is greater than or equal to the inlet air temperature, the dehumidification operation parameters can be kept unchanged; when the air outlet temperature is lower than the air inlet temperature, the dehumidifying operation parameters can be reduced.
Specifically, in this embodiment, the dehumidification operation parameters include a dehumidification frequency, a dehumidification rotation speed, and/or a dehumidification opening degree. That is, at least one of the dehumidification frequency, the dehumidification rotation speed, and the dehumidification opening degree may be adjusted based on the outlet air temperature and the inlet air temperature.
