Problems solved by technology

[0002] Most of the existing refrigeration control methods for refrigerators 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 leads to waste of energy and even reduces the service life of the refrigerator

Abstract

The present invention provides a refrigeration control method for a refrigerator. The refrigeration control method includes: detecting the current ambient temperature of the refrigerator; the refrigerator includes a first preset temperature and a second preset temperature, wherein the first preset temperature is lower than the second preset temperature Temperature, to judge the interval between the first preset temperature and the second preset temperature of the ambient temperature; detect the temperature of the air outlet and the return air outlet and obtain the temperature difference between the air outlet and the return air outlet; the refrigerator has the first preset temperature difference and the second preset temperature Two preset temperature differences, wherein the first preset temperature is smaller than the second preset temperature difference, and it is judged that the temperature difference between the air outlet and the return air outlet is in the interval between the first preset temperature difference and the second preset temperature difference; according to the environment The judging results of the temperature and the temperature difference between the air outlet and the air return jointly determine the speed increase percentage of the compressor and the fan. The refrigeration control method of the refrigerator of the present invention adjusts the rotational speeds of the compressor and the fan in a targeted manner, which not only makes the control more precise, but also reduces energy consumption and prolongs the service life of the refrigerator.

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 ...
