A liquid circulation refrigeration device

Abstract

The invention relates to a liquid circulation type refrigerating device which comprises a refrigerating circulation loop. Liquid refrigerant (2) coming out of a refrigerant storage tank (1) is delivered to a condensation evaporator (9) after pressurized by a low-temperature liquid pump (3). Cooling capacity is transmitted to the backflow refrigerant, the cooling capacity is released and the refrigerant with a raised temperature is delivered to a user system (6) for cooling supply. Refrigerant gas coming out of the user system (6) passes through a compressor (8), the condensation evaporator (9) and a throttle valve (10) and then returns the refrigerant storage tank (1). Therefore, the refrigerating circulation loop is formed. Due to the fact that the mode that the liquid circulation pump and the gas compressor are used for pressurizing and cooling supplying is adopted, the compression ratio of the gas compressor is greatly reduced, refrigerating capacity generated by compression of the refrigerant gas is effectively recovered, power consumption is obviously reduced, workloads such as installation and maintenance of the device are effectively reduced, environment is not affected, and economic benefits, social benefits and environment-friendly benefits are prominent. The liquid circulation type refrigerating device is a big breakthrough of a traditional refrigerating technology.

Description

technical field [0001] The invention relates to a liquid circulation refrigeration device, which specifically belongs to the technical field of refrigeration. Background technique [0002] Modern refrigeration technology, as a science, was developed in the middle and late nineteenth century. Before that, back to the ancestors of mankind, people knew the use of cold and simple artificial refrigeration very early: using the cellar as a cold storage room , has used spring water to cool storerooms for 5,000 years. [0003] After the twentieth century, refrigeration technology has made greater development: in 1910, the domestic refrigerator came out, and in 1917 it began to be put on the market as a commodity in the United States. In 1930, the emergence of freon refrigerants and the use of freon refrigerators brought new changes to refrigeration technology. In the 1970s, people conducted a lot of research on mixed working fluids, and began to use azeotropic mixed working fluids...

[0016] 2) The thermal efficiency of the Carnot cycle can only be less than 1, never equal to 1, because T 1 =∞ or T 2 =0 is impossible

[0019] 5) The limit point of the Carnot cycle is the ambient temperature of the atmosphere, and the Carnot cycle does not give a clear answer to the refrigeration process cycle below the ambient temperature

[0021] However, using the basic theory of thermodynamics cannot give a concise, clear and intuitive explanation of the refrigeration cycle.
