Abstract

The invention discloses a refrigeration system using waste heat of an engine. The refrigeration system using the waste heat of the engine comprises an exhaust vaporizer, a steam turbine, a gas compressor and a refrigeration turbine, wherein a heating fluid channel of the exhaust vaporizer is communicated with an exhaust passage of the engine, a working medium outlet of a heated fluid channel of the exhaust vaporizer is communicated with a working medium inlet of the steam turbine, a working medium outlet of the steam turbine is communicated with a liquid inlet of a liquid pressure pump through a condensation cooler, a liquid outlet of the liquid pressure pump is communicated with a working medium inlet of the heated fluid channel of the exhaust vaporizer, the steam turbine outputs power to the gas compressor, a compressed gas outlet of the gas compressor is communicated with a working medium inlet of the refrigeration turbine through a heat removal device, and a working medium outlet of the refrigeration turbine is communicated with an inlet, for gas to be compressed, of the gas compressor through a heat absorber. The refrigeration system using the waste heat of the engine is simple in structure, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to an engine waste heat refrigeration system. Background technique [0002] Utilizing engine waste heat is an effective way to improve engine energy utilization in disguise. At present, there are technologies that use engine waste heat for absorption refrigeration, ejector refrigeration, power generation, power generation and recooling, or power coupling. These solutions are relatively complicated. The three continuous supply of cooling, heating and power is an important way to effectively improve the energy utilization rate of the engine. In the scheme of continuous cooling, heating and power supply, both heating and power supply are mature technologies. If an effective and simple system can be invented to use the waste heat of the engine to Refrigeration will be significant. Contents of the invention [0003] In order to solve the above problems, the present invention proposes the fol...
