When heating operation (heat dehumidification) is carried out, high-temperature and high-pressure gas refrigerant discharged by the compressor enters the indoor lower heat exchanger to be condensed into liquid refrigerant, heat is released, and indoor air is heated; then, as the dehumidification valve is adjusted to be in an ON state, the liquid refrigerant throttles the refrigerant in the dehumidification valve through the throttling short pipe in the dehumidification valve, and the throttled low-pressure refrigerant flows into the indoor upper heat exchanger to evaporate and absorb heat, so that certain indoor air temperature is reduced, and the dehumidification function is realized. When the air conditioning system performs refrigeration operation (common refrigeration and dehumidification), the indoor upper heat exchanger and the indoor lower heat exchanger are completely communicated and are equal to one heat exchanger because the dehumidification valve is adjusted to be in an OFF state; at this time, the cooling and dehumidifying paths of the compressor, the outdoor heat exchanger and the indoor heat exchanger are the same as those of the conventional air conditioner.
The utility model discloses compare prior art's advantage and lie in:
(1) the utility model integrates the room air conditioner and the dehumidifier into a whole, simplifies the number of components, reduces the occupied space of the components and reduces the cost;
(2) the utility model divides the indoor heat exchanger into two parts which are connected in series, and the two parts are connected through the dehumidification valve, so that the air conditioner can carry out heat dehumidification when in heating operation, and the temperature can be raised for the room without being reduced in the dehumidification process; when the air conditioning system of the utility model is used for heating operation (thermal dehumidification), the dehumidification amount is small, the air conditioning system is suitable for dehumidifying and heating rooms under the room environment of 8-20 ℃, and the requirements of large humidity, cool and humid weather in winter at seaside and in southern areas are met;
(3) the common dehumidifier needs to often and manually remove accumulated water in the water tank, and the operation is troublesome; the utility model discloses the comdenstion water that the air conditioner produced at the dehumidification in-process can directly arrange the outdoor side through the indoor set drain pipe, has avoided the trouble that often falls water and brings.
