Problems solved by technology
like figure 1 As shown, this control method has two disadvantages. (1) The temperature of the cabinet is high. When the compressor needs to be started, the 1# compressor is always started first, and then the 2# compressor is started. After a long time of work, it will cause The cumulative working time of 1# compressor is greater than the cumulative working time of 2# compressor, and the service life of the two compressors is unbalanced
(2) When one compressor works to meet the cabinet temperature requirements, two compressors work at the same time, which will cause the compressor to start and stop repeatedly, which will increase power consumption

Embodiment Construction
[0045] (1) The temperature t in the box has been in the A zone, that is, when t>st+div1, a compressor is opened first. After two compressors are started
[0049] starting point=cabinet temperature setting value+cabinet temperature control compressor startup deviation value
[0052] Further, if the temperature in the box t< stop point, then close the compressor. The compressor runs for the maximum operating time, then
[0054] The temperature in the box t< stop point, then close a compressor.
[0056] When the temperature in the box reaches the B area, that is, t
[0059] Further, the ECO energy-saving mode control method is the control method disclosed above.

The invention discloses an ECO energy-saving mode control method and system of a self-cascading dual-system ultra-low temperature refrigerator, wherein the method includes: detecting temperature information inside the refrigerator and external environment temperature information, setting temperature control upper deviation and temperature control lower deviation information, and controlling The temperature inside the box reaches the set value of the box temperature; start the ECO energy-saving mode to control the energy saving of the refrigerator: set the refrigeration system in the refrigerator to include condensing fan 1 and condensing fan 2, compressor 1 and compressor 2, and both compressors The operating area is defined as area A, the area where both compressors must stop is area B, and the area where any compressor is running, that is, the operating area in ECO mode is area C; when the compressor runs to the maximum operating time, turn off the compressor, start another compressor. Through this control method, firstly, it can avoid the frequent start and stop of the compressor, and secondly, it can ensure the operation of one compressor. Compared with the normal mode, the purpose of energy saving can be achieved.
Description
An ECO energy-saving mode control method of a self-cascading dual-system ultra-low temperature refrigerator and the method thereof system technical field The present invention relates to refrigerator control field, relate in particular to a kind of ECO energy-saving mould of self-cascading dual-system ultra-low temperature refrigerators control method and system. Background technique [0002] The commonly used control method in the field of refrigerator refrigeration is normal mode control. As shown in Figure 1, this controller The method has two drawbacks, (1) the cabinet temperature is high, when the compressor needs to be started, always start the 1# compressor first, then start the 2# compressor After a long time of work, the cumulative working time of the 1# compressor will be greater than the cumulative working time of the 2# compressor, and the two Compressor life is unbalanced. (2) When one compressor works and the cabinet temperature requirements can be me...
