Abstract

The invention discloses a refrigeration circulating system with a double-stage-injection ejector. The refrigeration circulating system comprises a compressor, a condenser, a gas and liquid separator, a first throttling mechanism, a second throttling mechanism, a first evaporator, a second evaporator and the ejector with a double-stage injection function which are connected on a pipeline, the ejector is provided with two suction chambers and two diffusers, and two refrigerant flows with different evaporating temperatures from the two evaporators are respectively injected. The double evaporators with different evaporating temperatures are arranged and can match with change of the temperature of an air side better, and irreversible loss in an evaporation heat exchange process can be reduced. Simultaneously, higher outlet pressure of the ejector with the double-stage injection function can be obtained as compared with a conventional single-stage ejector, air suction pressure of the compressor is improved, air suction specific volume is reduced, and accordingly a performance coefficient and refrigerating capacity or heating capacity of unit volume of the system are further increased. Accordingly, the refrigeration system has remarkable advantages in terms of improving performances of a refrigeration system.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and heat pumps, and relates to an ejector with double-stage injection, in particular to a synergistic vapor compression refrigeration cycle system using the ejector. Background technique [0002] Vapor compression refrigeration cycle systems are widely used in air conditioners (machines) and air source heat pump water heaters and other fields. It has the characteristics of simple system structure, compactness and rapid cooling or heating. Especially in recent years, with the rapid growth of energy demand, the increasingly prominent environmental and climate issues and the development of low-carbon economy, vapor compression refrigeration technology, as an energy-saving and environmentally friendly refrigeration and heating technology, is improving energy utilization efficiency and reducing greenhouse gases. Its outstanding technical advantages are more obvious in terms of reducing emissions...
