Abstract

The invention discloses an ejection refrigeration circulation system with the advantages of higher accuracy, simple structure and convenience in application. The ejection refrigeration circulation system comprises an ejector, a gas generator, a condenser, a gas-liquid separator, an expansion valve, two evaporators and a circulation pump and has the structure key points that the evaporators are composed of a first evaporator and a second evaporator; the input end of the ejector is connected with the output end of the second evaporator; the input end of the second evaporator is connected with one end of the expansion valve; the other end of the expansion valve is connected with one end of the gas generator and the output end of the circulation pump separately; the other end of the gas generator is connected with the input end of the ejector; the output end of the ejector is connected with the input end of the first evaporator; the output end of the first evaporator is connected with the one end of the condenser; the other end of the condenser is connected with one end of the gas-liquid separator; and the other end of the gas-liquid separator is connected with the input end of the circulation pump.

Description

technical field [0001] The invention belongs to the technical field of spray refrigeration technology for low heat energy reuse, and in particular relates to a spray refrigeration cycle system. Background technique [0002] As a method of utilizing low-grade heat energy, ejection refrigeration has attracted more and more attention due to the rise of energy prices and the emphasis on the environment in recent years. Compared with other refrigeration methods, jet refrigeration has the following advantages: waste heat or waste heat from automobiles, industries, and solar energy can be used as driving energy; water can be used as a working medium, and there is no environmental pollution such as destruction of the ozone layer; the system does not contain moving parts, The work is stable and reliable. However, the coefficient of performance of ejector refrigeration systems is relatively low, thus limiting its widespread use. In order to improve the performance of an ejector refr...
