Problems solved by technology

Lithium bromide refrigeration equipment is huge, not suitable for use in small places, and the system is highly corrosive; and ammonia water absorption refrigeration requires a rectifier, which makes the system complicated and poor in reliability; and these two refrigeration devices require electricity. Driven solution pump, cannot completely get rid of the dependence on electric energy
The single-pressure absorption refrigerator has a compact structure and does not require electric energy, but the system is small and inconvenient to expand, and the cooling efficiency is low

Abstract

A non-electric vapor compression refrigeration device driven by thermal energy, which is used to feed in external heat sources for compression and refrigeration to output brine. A steam generator, an expander, and a condenser connected by pipelines, wherein the expander is used to convert the energy of the high-pressure steam into kinetic energy and output from the output shaft of the expander; Flow valve and evaporator. The evaporator is used for evaporating and absorbing heat to output the cooled brine. The condenser is respectively connected with the outlet of the compressor and the inlet of the throttle valve through pipelines. Among them, the output shaft of the compressor and the expander Connection for the operation of the compressor driven by the output shaft of the expander. Due to the high-pressure driving circuit, the compressor and the working medium pump are driven by using the high-pressure steam generated by the steam generator to drive the kinetic energy generated by the expander, and all electricity is consumed.

Description

technical field [0001] The invention relates to a vapor compression refrigeration device, in particular to a refrigeration device which utilizes thermal energy to drive the evaporation of an organic working medium, and then drives an expander to generate power, and belongs to the field of refrigeration machinery. Background technique [0002] Existing commercial and residential refrigeration devices are mainly vapor compression refrigeration devices driven by electric energy, but with the increasingly serious environmental problems and the increase of electricity load in summer, the production of thermal energy generated by solar energy and industrial emissions Equipment that uses waste heat as the driving force and makes it produce refrigeration will become an effective way to solve energy problems. [0003] However, the existing heat-powered refrigeration technologies are mainly lithium bromide absorption refrigeration technology, ammonia water absorption refrigeration, an...
