Abstract

The invention provides an air conditioner and a control method thereof. The air conditioner comprises a compressor, an indoor heat exchanger and an outdoor heat exchanger, a first throttling device isarranged between the outdoor heat exchanger and the indoor heat exchanger, the outdoor heat exchanger comprises a first outdoor heat exchange section and a second outdoor heat exchange section, and the first outdoor heat exchange section and the second outdoor heat exchange section are arranged in series; the air conditioner further comprises a short-circuit device, and the short-circuit device can perform short circuit or remove short circuit on the second outdoor heat exchange section; and the indoor heat exchanger comprises a first indoor heat exchange section and a second indoor heat exchange section, the first indoor heat exchange section and the second indoor heat exchange section are arranged in series, and a second throttling device is further arranged between the first indoor heat exchange section and the second indoor heat exchange section. According to the air conditioner, the on-way flow and heat loss of a refrigerant in the outdoor heat exchanger are reduced, the power consumption of a system is reduced, the energy efficiency of an air conditioning system is effectively improved, more energy is saved, and the problem that a user feels uncomfortable due to indoor temperature reduction in a dehumidification process of the air conditioning system is is further solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] Indoor temperature and humidity are important factors affecting the comfort of human living environment. The air conditioning system can perform cooling and heating to adjust the indoor temperature, and the air conditioner also has a dehumidification mode, but the dehumidification mode of the traditional air conditioner is: the refrigerant in the air conditioning system is in the state of refrigerating the indoor cycle, that is, the indoor heat exchanger is evaporative refrigeration. Heat absorption, when the temperature of the air passing through the heat exchanger in the air-conditioning room drops to the dew point temperature, water will precipitate and condense from the air, so as to achieve the effect of dehumidification, and the indoor temperature will drop or the electric heating will b...
