Embodiment Construction

[0012] refer to figure 1 , the specific implementation adopts the following technical scheme: it comprises an expansion valve 1, an evaporator 2, a compressor 3, a first condenser 4 and a second condenser 5; one end of the expansion valve 1 is connected with one end of the evaporator 2, and the evaporator The other end of 2 is connected with one end of compressor 3, the other end of compressor 3 is connected with one end of first condenser 4, the other end of first condenser 4 is connected with one end of second condenser 5, and the second condenser The other end of the device 5 is connected with the expansion valve 1.

[0013] The expansion valve 1 mainly plays the role of throttling and reducing pressure and regulating flow, and it also has the functions of preventing wet compression and liquid shock protection of the compressor and abnormal overheating.

[0014] The evaporator 2 is a circulating evaporator. The boiling solution passes the heating surface multiple times in...

Abstract

The invention provides a novel refrigeration device, which relates to the field of refrigeration equipment. One end of an expansion valve (1) is connected with one end of an evaporator (2), the other end of the evaporator (2) is connected with one end of a compressor (3), the other end of the compressor (3) is connected with one end of a first condenser (4), the other end of the first condenser (4) is connected with one end of a second condenser (5), and the other end of the second condenser (5) is connected with the expansion valve (1). The evaporation of refrigerants is utilized for directly cooling air, objects to be cooled are cooled by cold air, and then, high-pressure and high-temperature refrigerant steam sent out by the compressor is condensed into liquid. The novel refrigeration device has the advantages that the cooling speed is high, the heat transfer temperature difference is small, a system is very simple, the novel refrigeration device can be commonly applied, and the market blanks are made up.

Description

Technical field: [0001] The invention relates to the field of refrigeration equipment, in particular to a novel refrigeration device. Background technique: [0002] Refrigeration equipment is a device that combines a refrigerator with a facility that uses cold energy. Refrigeration devices are designed and constructed to effectively use cold energy to refrigerate food or other items; to conduct product performance tests and scientific research tests at low temperatures; to achieve certain cooling processes in industrial production, or to perform air conditioning. When items are cooled or frozen, a certain amount of heat will be released, and the enclosure structure of the refrigeration device will also transfer a certain amount of heat when it is in use. Therefore, in order to maintain the low temperature conditions in the refrigeration device, a refrigerator must be installed to continuously remove the heat, or use the melting of ice or the sublimation of dry ice t...
