Abstract

The invention discloses a temperature and coupling running controlling method of a double-compressor and double-refrigerating circuit refrigerator. The temperature and coupling running controlling method comprises the following steps: picking up current temperatures of a priority control compartment and a secondary control compartment; and monitoring the startup-shutdown state of a compressor in the priority control compartment: if the compressor in the priority control compartment is in a shutdown state, carrying out logic comparison on the picked current temperature of the secondary control compartment and a set starting temperature, a set shutdown temperature and set temperature offsets E1 and E2 to control the compressor to start up or shut down; and if the compressor in the priority control compartment is in a startup state, carrying out logic comparison on the picked current temperature of the secondary control compartment and a set starting temperature, a set shutdown temperature and set temperature offsets E3 and E4 to control the compressor to start up or shut down. When the temperature and coupling running controlling method is applied to the double-compressor and double-refrigerating circuit refrigerator with energy coupling, simultaneous starting and refrigerating time, i.e. coupling running time, of two refrigerating circuits can be prolonged, and the running efficiency of a system is improved.

Description

technical field [0001] The invention relates to a refrigerator temperature control technology, in particular to a method for controlling the temperature and coupled operation of a double-compressor double-refrigerating circuit refrigerator. Background technique [0002] With the development of the times and the improvement of people's living standards, consumers not only pay attention to the energy consumption level of refrigerators, but also put forward some new requirements for the form and function of refrigerators. Refrigerators have evolved from simple food low-temperature storage boxes to high-quality aspects such as precise temperature control, large volume, multiple temperature zones, energy saving and environmental protection, and quality and freshness preservation. The single circulation circuit of traditional refrigerators is difficult to ensure the precise control of the temperature of each temperature when designing multi-temperature refrigerators, and it is dif...
