Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioning unit and a control method thereof. The problem that when an existing air conditioning unit operates in a low-temperature environment, the heat exchange effect becomes poor due to the fact that the air return temperature is too low is solved. Therefore, the air conditioning unit comprises a refrigerant circulation system, a regenerative branch and a regenerative heat exchanger, the refrigerant circulation system comprises a refrigerant circulation pipeline, an indoor heat exchanger, a four-way valve, a gas-liquid separator, a compressor and an outdoor heat exchanger, and the indoor heat exchanger, the four-way valve, the gas-liquid separator, the compressor and the outdoor heat exchanger are arranged on the refrigerant circulation pipeline; based on the arrangement of the regenerative branch and the regenerative heat exchanger, a medium-temperature medium-pressure refrigerant can be used for heating the refrigerant before entering the gas-liquid separator so as to increase the return gas temperature, and the temperature of the refrigerant in the regenerative branch is further increased through the refrigerant flowing through an outdoor coil pipe; and in addition, the communicating time of the regenerative branch and the refrigerant circulation system is accurately judged according to the temperature of the outdoor coil pipe and the return air temperature, so that the air conditioning unit can complete defrosting in the shortest time.

Description

technical field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning unit and a control method thereof. Background technique

[0002] In order to maintain a comfortable ambient temperature, air-conditioning units have become an essential device in people's lives. Generally, an air conditioning unit includes a refrigerant circulation pipeline and an indoor heat exchanger, a four-way valve, a gas-liquid separator, a compressor, and an outdoor heat exchanger arranged on the refrigerant circulation pipeline, wherein the four-way valve is used to control the flow of the refrigerant The refrigerant flow in the circulation pipeline is reversed, and the compressor is used to assist the refrigerant to convert between gaseous and liquid states. During its operation, the refrigerant circulates and exchanges heat between the indoor heat exchanger and the outdoor heat exchanger, thereby To achieve the effect of changin...
