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.
[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.

Abstract

The invention discloses an operation control method for an air conditioner-refrigerator all-in-one machine. The operation control method comprises: starting the air conditioner-refrigerator all-in-one machine and operating a refrigeration mode; controlling a first bypass valve and a second bypass valve to be opened by 1 / 4, such that a bypass pipeline is communicated; controlling a first control valve, a fourth control valve and a sixth control valve to be opened and controlling a second control valve, a third control valve, a fifth control valve and a seventh control valve to be closed; controlling a compressor to be operated at high frequency, such that an indoor heat exchanger is closed; detecting temperatures of a freezing zone and a refrigerating zone; and controlling the air conditioner-refrigerator all-in-one machine according to time for the freezing zone and the refrigerating zone to reach a set temperature. According to the operation control method, electric heating for unfreezing is not required, not only is an unfreezing cost saved, but also the unfreezing efficiency is improved, the unfreezing energy consumption is reduced, and the problem of safety caused by electric leakage is avoided.

Description

Technical field [0001] The present 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] 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, but the refrigerator is basically shut down in winter in the north. The annual utilization rate of the two refrigeration appliances is not high. If they can be combined into one, it will save a lot of energy and material costs. [0003] Existing refrigerators generally use electric heating for thawing, which not only has high thawing cost and high energy consumption, but also is prone to dangers such as electric leakage. Summary of the invention [0004] The purpose of the present invention is to provide an operation control method fo...
