Air-cooled refrigerator and refrigerating system and refrigerating control method thereof

Abstract

The invention discloses an air-cooled refrigerator and a refrigerating system and refrigerating control method thereof. The system comprises a freezing chamber evaporator, a temperature changing chamber evaporator, a refrigerating chamber evaporator, a compressor, a condenser and a drying filter, wherein the temperature changing chamber evaporator and the refrigerating chamber evaporator are connected with the freezing chamber evaporator, and the compressor, the condenser and the drying filter are sequentially connected; a first controller is connected to the drying filter through a first pipeline and connected with the temperature changing chamber evaporator and a second controller; the second controller is connected with the freezing chamber evaporator and the refrigerating chamber evaporator; and a third controller is connected to the drying filter through a second pipeline and connected with the refrigerating chamber evaporator. According to the system, the third controller is arranged on the second pipeline between the drying filter and the refrigerating chamber evaporator, and then a new refrigerating cycle is formed; all refrigerating loops are controlled by detecting the temperature in all the chambers of the refrigerator and conducting switching operations of the controllers, therefore, the chambers can achieve simultaneous refrigerating, and the temperature lowering speed of the chambers in the initial stage of electrifying is increased.

Description

technical field [0001] The invention relates to the field of air-cooled refrigerators, in particular to an air-cooled refrigerator, its refrigeration system, and a refrigeration control method. Background technique [0002] In recent years, air-cooled refrigerators have been more and more sought after by users because of their advantages such as automatic defrosting and uniform temperature in each room. One of the biggest features of air-cooled refrigerator refrigeration is: use the rotation of fan blades to enhance the convective heat exchange between the hot air in the compartment and the evaporator, and at the same time, the pressure difference formed by the rotation of the fan blades can also strengthen the flow of air in the compartment. All can promote the rapid cooling of the refrigerator compartment. Because the multi-system air-cooled refrigerator can control the temperature of each room more accurately, and ensure the freshness of different types of food to the ma...
