Problems solved by technology

[0002] 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.

Abstract

The invention discloses an operational control method for an air-conditioner and refrigerator all-in-one machine. The operational control method includes the steps that the air-conditioner and refrigerator all-in-one machine is controlled to be powered up; the operating state of the air-conditioner and refrigerator all-in-one machine is acquired; when the air-conditioner and refrigerator all-in-one machine operates in a refrigeration mode, a third control valve is controlled to be opened a/b, a fifth control valve and a seventh control valve are closed, an outdoor heat exchanger, an indoor heat exchanger and a refrigerator are opened, and a compressor operates at a high frequency; the temperature of a freezing area and the temperature of a cold storage area are obtained; and when the temperature of the freezing area and the temperature of the cold storage area reach a set temperature, a first control valve, a second control valve, the third control valve and a sixth control valve are all controlled to be opened, a fourth control valve is opened c/d, the fifth control valve and the seventh control valve are closed, the outdoor heat exchanger, the indoor heat exchanger and the refrigerator are opened at the same time, and the compressor operates at a high frequency. According to the operational control method for the air-conditioner and refrigerator all-in-one machine, complementation of the air-conditioner and refrigerator functions can be achieved, and the overall operation efficiency is improved.

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] Therefore, how to integrate refrigerators and air conditioners more reasonably, realize functional complementarity, and improve overall operating efficiency is an urgent problem to be solved at present. Contents of the invention [0004] The object of the present invention is ...
