[0052] Optionally, the air conditioner controls the three-way valve to make the outdoor heat exchanger communicate with the first indoor heat exchanger and the second indoor heat exchanger according to the indoor environment temperature and the indoor environment humidity, which includes: in the case that the indoor environment temperature is in a first temperature interval and the indoor environment humidity is in a first humidity interval, the air conditioner controls the three-way valve to make the outdoor heat exchanger communicate with the first indoor heat exchanger and the second indoor heat exchanger, so that the refrigerant in the outdoor heat exchanger first enters the second indoor heat exchanger and then flows into the first indoor heat exchanger before throttling to heat indoor air. Specifically, the first temperature interval can be (-∞, 18℃], and the first humidity interval can be [80%, +∞). In this way, in the case that the indoor environment temperature is in the first temperature interval and the indoor environment humidity is in the first humidity interval, the three-way valve is controlled to make the second indoor heat exchanger and the throttling device respectively communicate with the outdoor heat exchanger, so that the refrigerant in the outdoor heat exchanger first enters the second indoor heat exchanger and then flows into the first indoor heat exchanger before throttling to heat indoor air, and the heated air is mixed with cold air on the surface of the first indoor heat exchanger to increase the outlet air temperature, thereby increasing the indoor temperature and realizing constant temperature dehumidification.

[0053] Optionally, in the case that the indoor environment temperature is not in the first temperature interval and the indoor environment humidity is not in the first humidity interval, the air conditioner controls the three-way valve to make the outdoor heat exchanger communicate with the first indoor heat exchanger, so that the refrigerant in the outdoor heat exchanger directly flows into the first indoor heat exchanger through the throttling device to realize normal refrigeration or heating function. In this way, in the case that the indoor environment temperature is not in the first temperature interval and the indoor environment humidity is not in the first humidity interval, the throttling device is made to communicate with the outdoor heat exchanger to realize normal refrigeration or heating function.

This involves controlling the three-way valve to connect the second indoor heat exchanger and the throttling device to the outdoor heat exchanger based on the indoor ambient temperature and humidity to achieve constant temperature dehumidification. Then, the target temperature of the indoor coil is determined based on the indoor ambient temperature and humidity. Finally, the compressor correction frequency is controlled based on the actual indoor coil temperature and the target temperature. In constant temperature dehumidification mode, the surface temperature of the indoor heat exchanger is more stable, resulting in a more stable outlet air temperature and ultimately a more stable indoor temperature. This more stable constant temperature dehumidification improves user comfort and enhances the user experience.

The air conditioner determines T based on Tin, Hin, and ΔT.e , comprising: the air conditioner calculates T e ' = T in - (100 - H in ) / 5 -△T. In this way, the dehumidification set temperature difference is first determined according to the indoor environment humidity, and then the indoor coil target temperature is determined according to the dehumidification set temperature difference, the indoor environment temperature and the indoor environment humidity. This is conducive to more accurately determining the indoor coil target temperature according to the indoor environment temperature and the indoor environment humidity, and then controlling the compressor correction frequency according to the indoor coil actual temperature and the indoor coil target temperature. In the case of running the constant temperature dehumidification mode, the surface temperature of the indoor heat exchanger is more stable, so that the outlet air temperature is more stable, and thus the indoor temperature is more stable, and the constant temperature dehumidification is more stably achieved, the user's comfort is improved, and the user experience is improved.

[0057] Optionally, the air conditioner controls the compressor correction frequency according to T e and T e , comprising: the air conditioner determines a preliminary change amount△f e of the current correction cycle frequency according to T e and T B '. The air conditioner calculates the corrected output amount H B of the current correction cycle according to△f out1_coil and the output amount H out_coil of the last correction cycle. The air conditioner calculates the filtered frequency change amount H out1_coil of the current correction cycle according to H out_coil and H outf_am . The air conditioner calculates the target correction frequency F n of the current correction cycle according to the current running frequency S outf_am of the compressor and H r . The air conditioner controls the compressor to adjust the frequency to F r . In this way, the preliminary change amount of the current correction cycle is first determined according to the indoor coil actual temperature and the indoor coil target temperature, and then the corrected output amount of the current correction cycle is determined according to the preliminary change amount of the current correction cycle and the corrected output amount of the last correction cycle, and then the filtered change amount of the current correction cycle is determined according to the corrected output amount of the last correction cycle and the corrected output amount of the current correction cycle, and then the filtered change amount of the current correction cycle is determined according to the current running frequency of the compressor and the corrected output amount of the current correction cycle and the frequency is adjusted to the frequency. This is conducive to more accurately controlling the compressor correction frequency according to the indoor coil actual temperature and the indoor coil target temperature. In the case of running the constant temperature dehumidification mode, the surface temperature of the indoor heat exchanger is more stable, so that the outlet air temperature is more stable, and thus the indoor temperature is more stable, and the constant temperature dehumidification is more stably achieved, the user's comfort is improved, and the user experience is improved.
