Operation control method of air conditioner and refrigerator all-in-one machine

Abstract

The invention discloses an operation control method of an air conditioner and refrigerator all-in-one machine. The method comprises the steps that the air conditioner and refrigerator all-in-one machine is started and operated in a refrigerating mode; a first bypass valve and a second bypass valve are controlled to open by one fourth, and an unfreezing zone is controlled to conduct unfreezing; a first control valve, a second control valve, a third control valve, a fourth control valve and a sixth control valve are controlled to open, and a fifth control valve and a seventh control valve are controlled to close; a compressor is controlled to operate at a high frequency, so that an indoor heat exchanger operates in a refrigerating mode; the temperature departure between the indoor temperature and a set temperature is obtained; and the air conditioner and refrigerator all-in-one machine is controlled according to the temperature departure. Electric heating unfreezing is not needed, the unfreezing cost can be reduced, the unfreezing efficiency can further be improved, the unfreezing energy consumption is reduced, and the security problems caused by electric leakage is avoided.

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...
