Refrigerator control method and system as well as refrigerator

Abstract

The invention discloses a refrigerator control method and system as well as a refrigerator. The refrigerator control method comprises the steps of judging whether the temperature of a refrigerating chamber is higher than or equal to the starting temperature of the refrigerating chamber or not; if yes, starting a draught fan to refrigerate the refrigerating chamber; judging whether the temperature of the refrigerating chamber is lower than or equal to the stopping temperature of the refrigerating chamber or not; if not, further judging the temperature of a freezing chamber is higher than or equal to the starting temperature of the freezing chamber or not; and if the temperature of the freezing chamber is higher than or equal to the starting temperature of the freezing chamber, starting the compressor to refrigerate the freezing chamber until the temperature of the refrigerating chamber is lower than or equal to the preset temperature, and then, stopping the compressor and the draught fan, wherein the preset temperature is lower than the stopping temperature of the refrigerating chamber. According to the method disclosed by the invention, the temperature fluctuation range of the refrigerating chamber can be effectively narrowed, which is beneficial to freshness keeping of foods; the stopping time of the draught fan is short, so that frosting is avoided and even eliminated, and the refrigerating efficiency of the refrigerator is increased; and the starting and stopping frequencies of the compressor are low, which is beneficial to prolonging of the service life of the compressor and improvement of the market competitiveness of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method and system for a refrigerator and the refrigerator. Background technique [0002] In the related art, for an air-cooled refrigerator with a manual damper for adjusting the opening of the air duct, the start and stop of the compressor and the fan depend on the temperature of the refrigerator compartment. That is, when the refrigerating room needs cooling, start the compressor and fan, and when the refrigerating room does not need cooling, the compressor and fan stop. Since the cooling efficiency of the compressor is relatively high during the startup period, the refrigerating room quickly meets the cooling requirements, and the fan is stopped. and compressor operation. This causes the compressor to start and stop relatively frequently, which affects the service life of the compressor. Moreover, the downtime of the fan is relatively long, and duri...

This causes the compressor to start and stop relatively frequently, affecting the service life of the compressor

Moreover, the downtime of the fan is relatively long, and during the downtime of the fan, natural convection will be formed between the refrigerating room and the freezing room through the air duct, that is, the humid and hot air in the refrigerating room enters the freezing room through the air duct, and the air is sent from the freezing room to the refrigerating room. Frost will form in the duct or the air duct of the freezer, which will affect the refrigeration performance of the refrigerator.
