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.

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 controlled to be powered on; 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, an outdoor heat exchanger and an indoor heat exchanger are controlled to be started, a refrigerator is closed, a first by-pass valve and a second by-pass valve are controlled to be closed, and a compressor is controlled to operate at a high frequency; the temperature deviation pn between an indoor environment temperature and a set temperature is acquired; when the temperature deviation pn is smaller than T1, a third control valve is controlled to be opened a / b, and accordingly the outdoor heat exchanger, the indoor heat exchanger and the refrigerator are started at the same time so as to control the compressor to operate at a high frequency; and when the air-conditioner and refrigerator all-in-one machine operates in a heating mode, the outdoor heat exchanger, the indoor heat exchanger and the refrigerator are controlled to be started, and the compressor is controlled to operate at the high frequency. By means of the operational control method for the air-conditioner and refrigerator all-in-one machine, the function of an air-conditioner and the function of the refrigerator can be complemented with each other, and the overall operating efficiency can be 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 ...
