Operation control method of air conditioner and refrigerator integrated machine

Abstract

The invention discloses an operation control method of an air-conditioner and refrigerator integrating machine. The operation control method comprises the following steps of: starting the air-conditioner and refrigerator integrating machine, and performing operation under a refrigeration mode; performing control to close a first bypass valve and a second bypass valve, and performing control to close a bypass pipeline; performing control to start a first control valve, a second control valve, a third control valve, a fourth control valve and a sixth control valve, and performing control to close a fifth control valve and a seventh control valve; controlling a compressor to perform high-frequency operation to enable an indoor heat exchanger to perform refrigeration; obtaining temperature deviation between indoor temperature and set temperature; and controlling the air-conditioner and refrigerator integrating machine according to the temperature deviation. In the operation control method disclosed by the invention, electric-heating unfreezing is not needed, so that not only can unfreezing cost be saved, but also unfreezing efficiency can be improved, energy consumption during unfreezing is reduced, and safety problems caused by electric leakage can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an operation control method of an air conditioner and refrigerator integrated machine. Background technique [0002] Existing air conditioners and refrigerators are two independent refrigeration equipment. The average usage time of air conditioners is less than 30% all the year round, and the utilization rate of refrigerators is relatively long. However, in the north, refrigerators are basically turned off in winter. The utilization rate of the two refrigeration appliances is not high throughout the year. If they can be combined into one, it will save a lot of energy and material costs. [0003] Existing refrigerators generally use electric heating to thaw, which not only has high thawing costs and high energy consumption, but also is prone to dangers such as electric leakage. Contents of the invention [0004] The object of the present invention is to provide an oper...
