Water refrigeration method and water refrigeration device using porous material

Abstract

The invention belongs to the field of refrigeration, and particularly relates to a water refrigeration method and a water refrigeration device using a porous material. According to the method, the nanoscale porous material is adopted, so that medium water flows into holes when passing through the porous material to form medium water with a large specific surface area; the medium water in the holesis evaporated and takes away heat under the vacuumizing action of a vacuum pump and under the cooperation of a sealing cavity formed outside the porous material, so that the temperature of the porousmaterial is reduced, the temperature of the passing medium water is reduced, and the purpose of cooling and refrigerating the medium water is achieved; and meanwhile the purpose of adjusting and controlling the refrigerating effect can be achieved by controlling the aperture, the porosity, the pipe wall, the external force and other factors. The refrigeration method has the refrigeration advantages of being easy to operate, environment-friendly and capable of achieving the refrigeration effect with water, raw materials are easy to obtain, and the refrigeration method can be widely applied tovarious refrigeration fields.

Description

technical field [0001] The invention belongs to the refrigeration field, and in particular relates to a water refrigeration method and a water refrigeration device utilizing porous materials. Background technique [0002] In the refrigeration industry, chillers are divided into air-cooled chillers and water-cooled chillers according to different cooling methods, and are divided into screw chillers, scroll chillers and piston chillers according to compressor types. chiller. Although the above forms are different, most of them use freon or ammonia as the refrigerant. Through the compression method, the refrigerant becomes liquid under high pressure, and the heat is taken away by circulating water or wind, and then the pressure drops through the throttling method. The refrigerant evaporates into gas in the evaporator, and the heat absorbed by the refrigerant is taken away by the refrigerant (water) during evaporation, so as to achieve the purpose of refrigeration. However, th...

Problems solved by technology

However, the refrigeration unit involves the compression and evaporation of the refrigerant, and the working pressure is generally above 1.0MPA, which is very dangerous. Once the pressure is overpressured during operation, it is very easy to cause safety accidents such as pressure vessel explosion, which has a high potential safety hazard. , and some refrigerants are irritating to a certain extent, such as ammonia, etc., which have high requirements for maintenance and construction, and most refrigerants such as freon, ammonia, etc., once leaked, will cause serious pollution to the atmosphere and the surrounding environment. At the same time, Since the refrigerant needs to be further compressed, cooled and circulated after evaporation, the energy consumption is high, and various components such as evaporators, condensers, compressors, etc. are involved, and a large amount of additional energy is required

[0003] Water is an abundant resource that is easy to obtain in nature, and compared with other refrigerants, it is safe, environmentally friendly, non-toxic, and low in cost. After pumping out, the water distribution system contacts with high-temperature air and then evaporates and absorbs heat to take away the heat in the air, thereby reducing the air temperature, which has the advantages of low energy consumption and environmental protection, but this method will make the humidity in the air more and more The higher the temperature, the cooling effect will decrease with the increase of humidity, and groundwater will be used as circulation, and most of the groundwater after passing through the fan circulation will be directly discharged into the sewer, which will cause waste of groundwater, so the country does not advocate the use of this kind of air conditioner. limited use
