Refrigeration control method for refrigerator

Abstract

The invention provides a refrigeration control method for a refrigerator. The refrigeration control method comprises the following steps that the current environment temperature of the refrigerator isdetected; the refrigerator is provided with a first preset temperature and a second preset temperature, the first preset temperature is less than the second preset temperature, and the interval, where the environment temperature is located, between the first preset temperature and the second preset temperature is judged; the temperatures of an air outlet and a return air inlet are detected, and the temperature difference between the air outlet and the return air inlet is acquired; the refrigerator is provided with a first preset temperature difference and a second preset temperature difference, the first preset temperature is less than the second preset temperature difference, and the interval, where the temperature difference between the air outlet and the air return inlet is located, between the first preset temperature difference and the second preset temperature difference is judged; and the rotating speed increasing percentages of a compressor and a fan are jointly determined according to a judgment result of the environment temperature and the temperature difference between the air outlet and the return air inlet. According to the refrigeration control method for the refrigerator, the rotating speeds of the compressor and the fan are adjusted in a targeted mode, the control is more accurate, and meanwhile, the energy losses are reduced, and the service life of the refrigerator is prolonged.

Description

technical field [0001] The invention relates to a refrigeration control method for a refrigerator. Background technique [0002] Most of the existing refrigerator cooling control methods only consider the ambient temperature as an influencing factor in the control of the speed of the compressor and the fan, and control the speed of the compressor and the fan by comparing the ambient temperature with the preset temperature value, but do not consider other factors. Influencing factors, especially the failure to take into account the temperature and use of the refrigerator, make the control of the compressor and fan speed inaccurate, which in turn leads to waste of energy and even reduces the service life of the refrigerator. [0003] In view of this, it is necessary to improve the refrigeration control method of the existing refrigerator to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a refrigeration control ...
