The invention discloses an operational control method of an air conditioner and refrigerator integrated machine. The operational control method includes the steps that the air conditioner and refrigerator integrated machine is controlled to conduct heating operation; a first control valve, a fourth control valve, a fifth control valve, a sixth control valve and a seventh control valve are controlled to be opened, a second control valve and a third control valve are controlled to be closed, an outdoor heat exchanger, an indoor heat exchanger and a refrigerator are controlled to be started, and a compressor is controlled to conduct high frequency operation; a first bypass valve and a second bypass valve are controlled to be closed; whether a frozen area and a cold storage zone of the refrigerator reach setting temperatures or not, and / or the temperature departure pn between the indoor environment temperature and the setting temperature is obtained; and the operational state of the air conditioner and refrigerator integrated machine is controlled according to detection results. By means of the operational control method of the air conditioner and refrigerator integrated machine, complementation of an air conditioner and the refrigerator can be achieved, and the overall running 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 ...
