Problems solved by technology

Because the four-way valve usually produces a lot of noise when it is reversed, and after the four-way valve is reversed, it will cause the indoor heat exchanger to enter the defrosting mode. In the defrosting mode, the indoor heat exchanger will stop heating, making Lower ambient temperature

Abstract

The invention discloses an air-conditioning system, which comprises a four-way valve, an outdoor heat exchanger, an indoor heat exchanger, a compressor, a throttling part and a control module, wherein the four-way valve comprises an exhaust end, a suction end, a condenser end and an evaporator end; one end of the outdoor heat exchanger is communicated with the throttling part, and the other end of the outdoor heat exchanger is communicated with the condenser end; the indoor heat exchanger comprises two sets of heat exchange pipelines; each of the two sets of heat exchange pipelines comprises at least one heat exchange flow path; the control module is used for controlling one end of the heat exchange flow path in one of the heat exchange pipelines to be communicated with the evaporator end and the other end of the heat exchange flow path in one of the heat exchange pipelines to be communicated with the throttling part and controlling one end of the heat exchange flow path in the other heat exchange pipe to be communicated with the exhaust end and the other end of the heat exchange flow path in the other heat exchange pipe to be communicated with the suction end when a defrosting command is detected. The invention also discloses a control method for the air-conditioning system. According to the air-conditioning system and the control method for the air-conditioning system disclose by the invention, the running noise of the air-conditioning system is reduced; the continuous heating effect is achieved; the phenomenon that the comfort level of the environment is lower due to the fact that indoor temperature is lowered during a defrosting process is prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a defrosting control method for the air conditioning system. Background technique [0002] As we all know, in the prior art, when the air-conditioning system is in heating operation, it is usually necessary to defrost the indoor heat exchanger, so as to improve the heat exchange energy efficiency of the indoor heat exchanger. In a traditional air conditioning system, when a defrosting command is detected, a four-way valve reversing scheme is usually used for defrosting. Because the four-way valve usually produces a lot of noise when it is reversed, and after the four-way valve is reversed, it will cause the indoor heat exchanger to enter the defrosting mode. In the defrosting mode, the indoor heat exchanger will stop heating, making The ambient temperature drops. [0003] The above content is only used to assist in understanding the techn...
