Refrigeration control method, refrigeration control device and refrigerator

Abstract

The invention provides a refrigeration control method, a refrigeration control device and a refrigerator. The refrigeration control method comprises the following steps: detecting the outdoor environmental temperature of the refrigerator; determining the temperature range of the outdoor environmental temperature; and controlling a compressor of the refrigerator to enter a working mode corresponding to the temperature range. Through the technical scheme, the situation that the temperature in a refrigerator body is compensated only by a heater is avoided, and the working mode of the compressor can be directly determined according to the outdoor environmental temperature, so that the compressor can be directly turned on or off according to the outdoor environmental temperature, and thus the problem of a single-system computer refrigerator that the poor starting of the compressor is caused by the limited compensation ability of the heater when the outdoor environmental temperature is relatively low is solved; in addition, the existing compensating heater can be eliminated, so that the problem that the starting of the compressor is poor when the outdoor environmental temperature is too low is solved, and the production cost of the refrigerator is also reduced.

Description

technical field [0001] The present invention relates to the technical field of refrigerators, in particular to a refrigeration control method, a refrigeration control device and a refrigerator. Background technique [0002] Existing single-system computer refrigerators generally control the start and stop of the compressor separately through the refrigerator sensor. When the ambient temperature is low, the compensation heater on the back of the refrigerator can be turned on to heat the inside of the refrigerator so that The sensor reaches the switch-on point to start the compressor. [0003] However, when the ambient temperature is low, due to the small heat transfer temperature difference between the inside and outside of the refrigerator, only the heater is used to compensate the temperature inside the box. Under some severe conditions, the heater’s capacity is not enough to compensate the indoor temperature. For example, when the room temperature is below 0°C, Or a large...

Problems solved by technology

[0003] However, when the ambient temperature is low, due to the small heat transfer temperature difference between the inside and outside of the refrigerator, only the heater is used to compensate the temperature inside the box. Under some severe conditions, the heater’s capacity is not enough to compensate the indoor temperature. For example, when the room temperature is below 0°C, Or a large amount of food put in the refrigerator blocks the heater. These situations will cause the compressor to fail to start in time, resulting in the failure of the refrigerator to cool and affecting the storage effect of food.

[0004] Therefore, how to prevent the compressor of the refrigerator from being unable to start in time under harsh environments such as low ambient temperature has become a technical problem to be solved urgently.
