Abstract

A steam jet refrigeration cycle system comprises a producer, an evaporator, a condenser, a circulation pump, a throttle valve and main and secondary injectors. The producer is used for producing the high-pressure refrigerant working steam. The main injector is used for jetting the low-pressure refrigerant steam coming from the evaporator and the secondary injector is used for jetting the low-pressure refrigerant steam coming from the main injector. The circulating pump outputs the high-pressure refrigerant liquid. The refrigerant liquid coming from one outlet of a diffuser returns to the producer and the refrigerant gas-liquid mixture coming from the other outlet enters to the condenser to condense. The produced refrigerant liquid is divided into two ways, one way is sent to the secondary injector by the circulating pump and the other enters to the evaporator through the throttle valve. The refrigeration is realized by evaporative heat-absorbing of the refrigerant in the evaporator.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, relates to a thermodynamic cycle of steam injection refrigeration and its system, in particular to a steam injection refrigeration cycle system in which an auxiliary ejector (liquid-gas type) realizes pressurization and heat recovery. The system can be applied to low-grade thermal energy such as solar energy, low-temperature waste heat, and waste heat-driven ejector refrigeration devices. Background technique [0002] Vapor injection refrigeration is a refrigeration technology driven by heat energy. Compared with absorption and adsorption refrigeration driven by heat energy, it has simple system structure, no moving parts (except circulation pump), low investment and operating costs, and refrigerant Unique advantages such as good selectivity. Since the mid-1950s, people have been working on the research and application of vapor injection refrigeration systems driven...
