Refrigerator, refrigeration cycle system of refrigerator and refrigeration control method of refrigerator

Abstract

The invention discloses a refrigerator, a refrigeration cycle system of the refrigerator and a refrigeration control method of the refrigerator. The refrigerator comprises a refrigerating chamber, a freezing chamber and the refrigeration cycle system. By arranging a flow regulating valve, control over compressor exhaust flow flowing through a refrigerating chamber evaporator or a freezing chamber evaporator of the refrigeration cycle system is achieved, and the situation that the compressor exhaust flow flowing through the refrigerating chamber evaporator or the freezing chamber evaporator is constant, and the refrigeration efficiency is poor can be effectively avoided. A temperature sensor system is arranged to detect related temperature parameters of the refrigeration cycle system in different refrigeration modes in real time, and then the opening degree of a flow regulating valve is controlled according to the temperature parameters, so that the compressor exhaust flow of the refrigeration cycle system in different refrigeration modes is accurately controlled, the regulation and control strategy of the compressor exhaust flow is optimized, and the refrigeration efficiency of the refrigeration cycle system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to a refrigerator, a refrigeration cycle system and a refrigeration control method. Background technique [0002] Along with the raising of economic development and people's living standard, refrigerator has become requisite household appliance in people's daily life already. The refrigerator mainly realizes the reduction of the temperature of the food itself through its internal refrigeration cycle system, delays the deterioration of the food, and thus achieves the effect of long-term storage. [0003] Most of the existing refrigerators are provided with a refrigerating chamber and a freezing chamber. In the double refrigerating cycle system, the system is controlled to enter the refrigerating mode or the freezing mode through the switching of the solenoid valve. After the refrigerator is powered on, it first enters the refrigerating and cooling mode, and the exhaust ...
