Refrigerating system, refrigerator with same and control method thereof

Abstract

The invention provides a refrigerating system, a refrigerator with the same and a control method thereof, wherein the refrigerating system comprises a compressor, a condenser, a switching unit, a refrigerating chamber capillary, a refrigerating chamber evaporator, a variable-temperature chamber capillary, a variable-temperature chamber evaporator and a freezing chamber evaporator, wherein an inlet of the condenser is connected with an outlet of the compressor; the switching unit is provided with an inlet, a first outlet and a second outlet, and the inlet of the switching unit is connected with the outlet of the condenser; the inlet of the refrigerating chamber evaporator is connected with the first outlet of the switching unit through the refrigerating chamber capillary; the inlet of the variable-temperature chamber evaporator is connected with the second outlet of the switching unit through the variable-temperature chamber capillary; and the inlet of the freezing chamber evaporator is connected with the outlet of the variable-temperature chamber evaporator and the outlet of the refrigerating chamber evaporator, and the outlet of the freezing chamber evaporator is connected with the inlet of the compressor. The refrigerator using the refrigerating system provided by the invention has the advantages of low noise, low energy consumption and low cost.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration system, a refrigerator with the refrigeration system and a control method for the refrigerator. Background technique [0002] With the continuous development of society, there are more and more types of food, and different types of food need to be stored at different temperatures to extend the freshness period. At present, due to the wide variety of food and different temperature requirements for different foods, the traditional two-door refrigerator food preservation equipment can no longer meet the user's requirements for food preservation. The two-door refrigerator can only be set to two temperatures, so it can no longer meet user requirements. [0003] Therefore, the three-door refrigerator developed accordingly. The three-door refrigerator can meet more temperature requirements of users. For example, the fresh-keeping temperature of green lea...

AI Technical Summary

Problems solved by technology

However, the traditional three-door refrigerator adopts three-display control and three-system design. Since the traditional three-door refrigerator uses three capillary tubes and a three-position four-way valve for control, the system has high operating noise, high cost and high energy consumption.
