Problems solved by technology

However, since this method judges whether defrosting is necessary and the length of defrosting time through some indirect conditions, rather than directly judging from the amount of frosting on the evaporator, there may be defrosting not in time, defrosting is not Completely, the defrosting time is too long and the power consumption is too large, etc.

Embodiment approach

[0034] According to an embodiment of the defrosting control method for refrigeration equipment of the present invention, it further includes: after the compressor runs for a preset first time threshold time and the value of the evaporator temperature sensing package is smaller than the preset first temperature value, start Perform the acquisition steps described. Such as figure 2 As shown, if it is not the first power-on or after the detection steps are performed for the first time, the compressor runs for the preset first time threshold time Nδ minutes, and then obtains the value H1 of the evaporator temperature-sensing package. If the value H1 of the evaporator temperature-sensing package is greater than Preset the first temperature value Hδ, then the compressor will run for the preset first time threshold time Nδ minutes; if the value H1 of the evaporator temperature sensing package is less than the preset first temperature value Hδ, the acquisition step is performed to co...

Abstract

The invention provides a refrigerating equipment defrosting control method and a device and refrigerating equipment with the device. The method comprises the following steps: an acquiring step: evaporator images are acquired under illuminating conditions; a judging step: the evaporator frost quantity is judged according to the acquired evaporator images; and a defrosting step: a defrosting heater is controlled to start or stop defrosting according to the evaporator frost quantity. On the basis of accurately judging the evaporator frost quantity, the accurate defrosting of an evaporator is realized, and the cost is low; and in addition, when the refrigerating equipment is primarily electrified, the evaporator faults can be detected.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a defrosting control method and device for refrigeration equipment and refrigeration equipment with the device. Background technique [0002] After the refrigeration equipment runs for a period of time, frost will gradually form on the evaporator. If the defrosting operation cannot be carried out in time, the frost layer will accumulate and thicken, which will seriously affect the cooling effect of the refrigeration equipment. Therefore, the defrosting problem of the evaporator of the refrigeration equipment has always been a problem that manufacturers need to solve urgently. [0003] At present, most of the defrosting methods are based on the running time of the compressor of the refrigeration equipment and the number of door switches to judge whether defrosting is needed; Counting Refrigerator Defrost Control System and Defrost Control Method", etc., are constantly corre...
