Abstract

The invention provides a refrigeration equipment control method and system and refrigeration equipment. Single running time of a compressor is used as a measuring standard for working stations of the refrigeration equipment; when the running time is long, it is judged that the refrigeration equipment is in a high-load compression working station, at the moment, the compressor of the refrigeration equipment needs to provide relatively more compression refrigerant for refrigeration, and a large compression volume is needed; when the running time of the refrigeration equipment is short, it is judged that the refrigeration equipment is in a low-load compression working station, and a small compression volume is needed; when it is judged that the compressor is in the high-load or low-load compression working station, the appropriate compression volume meeting requirements can be provided, and the circumstance that energy is wasted due to the fact that the refrigeration effect is poor or excessive is avoided. According to the judgment results for the working stations of the refrigeration equipment, the turning direction of the compressor is set before next starting, meanwhile, energy waste is effectively avoided, unnecessary product energy consumption is reduced, and the product market competitiveness is improved.

Description

technical field [0001] The present invention relates to the field of household appliances, in particular to a method and system for controlling refrigeration equipment and refrigeration equipment. Background technique [0002] At present, in the existing computer temperature-controlled refrigerators, the cost of the fixed-frequency compressor is more economical, but it needs to be started and stopped frequently to control the temperature during operation, and the compression volume of the compressor cannot be adjusted according to the size of the heat load. , which will lead to insufficient energy saving; while the frequency conversion compressor is more energy efficient, but its cost is higher, and the control circuit and wiring of the frequency conversion compressor are more complicated. [0003] Therefore, it is an urgent problem to be solved to design a refrigeration equipment control method, system and refrigeration equipment of a fixed-frequency compressor with a simpl...
