Refrigeration system and refrigerator thereof

Abstract

The invention discloses a refrigeration system and a refrigerator thereof, and relates to the field of refrigerators. The refrigeration system comprises a compressor, a condenser, a filter, an electromagnetic valve assembly, a capillary tube assembly and an evaporator assembly; the evaporator assembly comprises a first evaporator and a second evaporator; the inlets and outlets of the first evaporator and the second evaporator can be switched and are used for reversing the flowing directions of refrigerants in the first evaporator and the second evaporator; the electromagnetic valve assembly comprises a first electromagnetic valve and a second electromagnetic valve; the first electromagnetic valve and the second electromagnetic valve are used for switching connection and disconnection of different flow paths; and the two evaporators are used as the high-temperature and low-temperature evaporators separately. Through the new design of the refrigeration system, the high operation reliability of the refrigeration system is ensured, switching of different refrigeration effects of the variable-temperature evaporators is achieved by controlling the variety of capillary tubes correspondingto the variable-temperature evaporators and the connection and disconnection functions of the electromagnetic valve assembly, the effect of the total variable-temperature refrigerator is achieved, and various requirements of users can be met to the great extent.

Description

technical field [0001] The invention belongs to the field of refrigerators, and in particular relates to a refrigeration system and a refrigerator thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the volume and functions of refrigerators are also getting higher and higher. First of all, in terms of volume requirements, judging from the sales data of refrigerators in recent years, the sales volume of large-volume refrigerators has been increasing year by year, indicating that large-volume refrigerators are gradually becoming the standard equipment for most households. Secondly, as far as the requirements for the function of the refrigerator are concerned, with the abundance of materials, especially during the holidays, different types of food and different storage methods are different in different regions of the world, and the requirements for freshness and safety of food are increasing. higher. For example, dur...
