Air-conditioning system and air-conditioning control method

Abstract

The invention provides an air-conditioning system and an air-conditioning control method. The air-conditioning system comprises an outdoor unit and an indoor unit which is connected with the outdoor unit, wherein the indoor unit includes a housing, a first heat exchanger and a second heat exchanger; the first heat exchanger and the second heat exchanger are arranged in the housing; the first heat exchanger is connected with a first refrigerant interface of the outdoor unit; the second heat exchanger is connected with first heat exchanger, and is connected with a second refrigerant interface of the outdoor unit; the indoor unit also includes a first expansion valve; the first expansion valve is arranged between the first heat exchanger and the second heat exchanger; when the air-conditioning system is used, the first expansion valve is controlled in a throttling state; when the air passes through the first heat exchanger in low temperature, the moistures in the air become drops of water through condensation and the drops of water leave on the first heat exchanger, so that the humidity of air is reduced; and when the low temperature air with the reduced humidity passes through the second heat exchanger in high temperature, the heat is absorbed, so that the temperature rises. Therefore, the air-conditioning system conveniently achieves the effect of constant temperature and dehumidification.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system and an air conditioning control method. Background technique [0002] At present, the existing air-conditioning systems with dehumidification function are mainly aimed at the air-conditioning systems of the computer rooms. The common household air conditioners only have cooling or heating functions, but not dehumidification functions. During the alternating seasons of spring and summer in the south, the air humidity is high, and people often need to buy another dehumidifier for dehumidification, resulting in a large number of home appliances and occupying space. [0003] Patent No. CN104006584A discloses a three-pipe air conditioner and its refrigerant flow switching device. Although the refrigerant flows to the switching device, a part of multiple indoor heat exchangers can be cooled while the other part can be heated. However, this ...
