Specifically, the refrigeration apparatus 100 may be a home air conditioner or a central air conditioner. When the refrigeration apparatus 100 is a central air conditioner, the refrigeration apparatus 100 may be a multi-split system, such as a multi-split system.
The control method of the refrigeration device 100 according to the embodiment of the invention comprises the following steps:
and receiving a dehumidification instruction, and acquiring an indoor set temperature Ts and an indoor set humidity Hs. Specifically, the indoor set temperature Ts may be a temperature set by the user when the user selects the dehumidification mode or may be a temperature set by the system by default when the dehumidification mode is selected. The indoor set humidity Hs may be a humidity set by the user when the user selects the dehumidification mode, or may be a humidity set by the system by default when the dehumidification mode is selected.

Specifically, can detect indoor ambient temperature TR through ambient temperature bulb 8, utilize humidity transducer to detect indoor ambient humidity HR to make the testing process simple and convenient.
And when the indoor environment temperature TR is less than or equal to the indoor set temperature Ts and the indoor environment humidity HR is greater than the indoor set humidity Hs, the opening degree of the throttling element 3 is reduced.
Specifically, when a dehumidification command is received, the refrigeration apparatus 100 is controlled to enter a dehumidification mode, and the compressor 4 is controlled to start up so that the tube temperature of the refrigeration apparatus 100 is less than the dew point temperature to perform dehumidification. It can be understood that, in the dehumidification mode, the cooling device 100 cools down the indoor environment, and the indoor environment temperature will decrease.
In the dehumidification process, the indoor environment temperature TR and the indoor environment humidity HR are detected, and whether the indoor environment temperature TR is lower than the indoor set temperature Ts and whether the indoor environment humidity HR is higher than the indoor set humidity Hs is judged.
When TR is less than or equal to Ts and HR is more than Hs, the temperature is reduced to the required temperature at the moment but the humidity does not meet the condition, the opening degree of the throttling element 3 is controlled to be reduced, so that the heat exchange area of the two-phase refrigerant is reduced, the effective heat exchange area of the indoor heat exchanger 1 is reduced, the superheat degree of the indoor unit is increased, the refrigerating capacity is reduced, the reduction speed of the indoor environment temperature is slowed down, and even the indoor environment temperature is prevented from continuously reducing.
It should be noted that, during the operation of the refrigeration apparatus 100, when the indoor ambient temperature drops below the indoor set temperature and the difference between the indoor ambient temperature and the indoor set temperature is greater than the set difference, the refrigeration apparatus 100 may start the shutdown mode in order to save energy and avoid the influence of too low temperature on the comfort of the user.

In some embodiments of the invention, the indoor ambient temperature TR and the indoor ambient humidity HR are detected every first period of time t to determine whether to decrease the opening of the restriction element 3. Specifically, the time interval between the detection of the indoor ambient temperature TR and the detection of the indoor ambient humidity HR is a first time period t, when TR is detected to be less than or equal to Ts and HR is detected to be greater than Hs, the opening degree of the throttling element 3 is controlled to be reduced, and when TR is detected to be greater than Ts and/or HR is detected to be less than Hs, it is determined that the opening degree of the throttling element 3 does not need to be reduced.
It can be understood that the changes of the indoor ambient temperature TR and the indoor ambient humidity HR take time, and therefore, according to the control method of the embodiment of the present invention, the reliability of the detection result can be ensured, the energy consumption can be saved, and the system failure due to frequent detection can be avoided by detecting the indoor ambient temperature TR and the indoor ambient humidity HR at the interval time period to determine whether to decrease the opening degree of the throttling element 3 instead of detecting at all times.

Optionally, the value of the constant a ranges from 1 to 10, for example, the value of the constant a may be 5, 6, 7, 8, and the like. It should be noted that the value of the opening adjustment Δ E of the throttling element 3 is dependent on the calculated value of fx, which means that the value of the opening adjustment Δ E is the same as the calculated value of fx. Therefore, the opening of the throttling element 3 is adjusted according to the value of the obtained opening adjustment quantity delta E at every time, the opening adjustment delta E of the throttling element 3 can be obtained according to the actual environmental condition, the refrigerating capacity can be reduced according to the actual condition, the refrigerating effect on the indoor environment is reduced, the shutdown phenomenon caused by the fact that the temperature of the indoor environment drops too fast can be avoided, the indoor environment can be continuously dehumidified, and the dehumidifying effect of the refrigerating device 100 is ensured.
