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 a running control method for an air conditioner and refrigerator all-in-one machine. The running control method comprises the step of controlling the air conditioner and refrigerator all-in-one machine to be powered on, the step of obtaining the running status of the air conditioner and refrigerator all-in-one machine, the step of controlling 1 / 4 of a fourth control valve to be opened, controlling a fifth control valve and a seventh control valve to be closed, controlling an outdoor heat exchanger, an indoor heat exchanger and a refrigerator to be opened, and controlling a compressor to run at high frequency when the air conditioner and refrigerator all-in-one machine is subjected to refrigeration running, the step of obtaining the temperature deviation pn between indoor environment temperature and set temperature, and the step of controlling a first control valve, a second control valve, the fourth control valve and a sixth control valve to be fully opened, controlling 1 / 4 of a third control valve to be opened when the temperature deviation pn is smaller than T1 to enable the outdoor heat exchanger, the indoor heat exchanger and the refrigerator to be opened simultaneously, and controlling the compressor to run at high frequency. The running control method for the air conditioner and refrigerator all-in-one machine can realize complementation of functions of an air conditioner and functions of the refrigerator, and improves the whole running efficiency.

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 ...
