Operation control method of air conditioner and refrigerator integrated machine

Abstract

The invention discloses an operational control method for an air-conditioner and refrigerator all-in-one machine. The method includes the steps that the air-conditioner and refrigerator all-in-one machine is started to operate in a refrigeration mode; a first by-pass valve and a second by-pass valve are controlled to be closed; a first control valve, a fourth control valve and a sixth control valve are controlled to be opened, and a second control valve, a third control valve, a fifth control valve and a seventh control valve are controlled to be closed; a compressor is controlled to operate at a high frequency, so that an indoor heat exchanger is shut down; the temperature of a freezing area and the temperature of a cold storage area are detected; and an unfreezing area is controlled to be unfrozen according to the time for the freezing area and the cold storage area to reach the set temperature. According to the operational control method, no electric heating unfreezing is required, and unfreezing cost can be reduced; and meanwhile unfreezing efficiency can be improved, unfreezing energy consumption is reduced, and the problem of safety caused by electric leakage is solved.

Description

technical field 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 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. 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 The object of the present invention is to provide an operation control method of an air c...

Problems solved by technology

The existing air conditioner and refrigerator are two independent refrigeration equipment. The average annual use time of the air conditioner is less than 30%, and the utilization rate of the refrigerator is relatively long. However, in the north, the refrigerator is basically turned off in winter.

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.
