Specifically, the exhaust gas of the compressor 1 enters the first branch pipe of the flow divider 3 through the first heat exchanger 2, flows to the first throttling element 41, enters the second heat exchanger 42 for heat exchange and refrigeration, and then returns to the suction port of the compressor 1 through the third branch pipe of the collector 5, so that a refrigeration cycle, that is, a temperature regulation subsystem is formed to realize a refrigeration function. It will be further understood that when the first and second cut-off valves 43, 63 are provided in the system, the first cut-off valve 43 should be in an open state and the second cut-off valve 63 should be in a closed state.
Single dehumidification mode: the temperature conditioning subsystem will now stop running and the humidity conditioning subsystem will run normally. Specifically, the exhaust gas of the compressor 1 enters the second branch pipe of the flow divider 3 through the first heat exchanger 2, flows to the second throttling element 61, enters the third heat exchanger 63 for heat exchange and refrigeration, and then returns to the air suction port of the compressor 1 through the fourth branch pipe of the flow collector 5, so that a condensation dehumidification cycle, namely a humidity regulation subsystem is formed to realize a dehumidification function. It will be further understood that when the first and second cut-off valves 43, 63 are provided in the system, the second cut-off valve 63 should be in an open state and the first cut-off valve 43 should be in a closed state.

the rotation speed of the compressor is controlled according to the △ T.
Specifically, when △ T is higher than a first set threshold value, the rotating speed of the compressor is controlled to be at a first operating frequency, the temperature difference between the detection value of the indoor environment temperature sensor and the program set temperature is large, for example, △ T is more than 5 ℃, the variable frequency compressor runs high frequency, for example, the variable frequency compressor runs at 80Hz, the flow rate of the refrigerant of the two systems is accelerated, the mass flow is increased, the heat exchange capacity of the temperature adjusting subsystem and the humidity adjusting subsystem is maximized, the temperature of the two systems can be reduced and dehumidified at the fastest speed, and the problem that when the two systems are simultaneously opened by using the fixed frequency compressor, the refrigerating capacity of the temperature adjusting system is reduced due to the fact that the refrigerant is shunted, and the temperature.
When △ T is higher than a second set threshold and not higher than a first set threshold, controlling the rotation speed of the compressor to be at a second operation frequency, wherein the temperature difference between the detection value of the indoor loop temperature sensor and the program set temperature is slightly larger, for example, 5 ℃ is more than or equal to △ T and more than 3 ℃, the variable frequency compressor runs at a medium and high frequency, for example, the variable frequency compressor runs at a medium speed of 50Hz or 40Hz, the flow rate of the refrigerant of the two systems is moderate, the mass flow is moderate, the heat exchange quantity of the temperature regulating system and the dehumidifying system is at a medium level, and the temperature can be reduced and
after the double systems operate for a period of time, the temperature difference between the detection value of the indoor environment temperature sensor and the temperature set by the program is smaller, for example, △ T is close to 0 ℃, at the moment, the cold quantity required by the temperature regulating system is low, the variable frequency compressor can run at low frequency to maintain the low-load requirement, for example, the variable frequency compressor operates at low speed of 10Hz or 20Hz, the flow rate of the refrigerant of the double systems is low, the mass flow is low, the heat exchange quantity of the temperature regulating system and the dehumidifying system is at the low-load operation level, at the moment, the power of the compressor is very low, and the low cold quantity requirement is maintained in the most economical operation mode.
