Circulating refrigerating method and refrigerating circulating system thereof

Abstract

The invention provides a circulating refrigerating method. As a refrigerant is expanded, the flow speed of the refrigerant is increased, kinetic energy is increased, pressure and temperature are reduced, the refrigerant absorbs heat of a cold medium in an evaporator to be evaporated, the cold medium releases the heat to reduce the temperature to achieve refrigerating, the refrigerant absorbing the heat is expanded, the flow speed is increased, the refrigerant enters a diffusion pipe to be compressed, the flow speed is reduced, the pressure and the temperature rise, refrigerant steam enters a condenser to be condensed into liquid, the refrigerant releases the heat to be condensed into the refrigerant liquid to enter a liquid pump so that refrigerating circulation can be formed, the evaporation degree of the refrigerant entering the diffusion pipe is not limited, water can be used as the refrigerant, the problems that the refrigerant like Freon destroys the atmospheric ozone layer, and equipment is corroded by a chemical absorption agent used in a liquid-steam absorption system in the refrigerating process are solved, the refrigerant absorbs the heat of the low-temperature cold medium in the evaporator, and releases the heat in the condenser through diffusion and temperature rising, the cooling medium obtains the heat, and the temperature rises to supply the heat. The invention provides a refrigerating circulating system.

Description

technical field [0001] The invention belongs to the technical field of heat energy utilization and processing and equipment, and in particular relates to a cycle refrigeration method and a refrigeration cycle system thereof. Background technique [0002] At present, there are two main forms of refrigeration commonly used: one is an electric-driven mechanical vapor compression system, and the other is a liquid-vapor absorption system. However, both of these methods have disadvantages. The mechanical vapor compression type has high power consumption, large equipment investment, and high operating costs. Refrigerants such as Freon are used, which affect the environment and destroy the ozone layer of the atmosphere. The heat utilization coefficient of the liquid-vapor absorption system is not high, the equipment is huge, the economy is relatively poor, and the use of chemical absorbents is easy to corrode. In addition, the mechanical vapor compression refrigerator has certain r...
