Active balance pressure jet refrigeration system

Abstract

The invention relates to an active balance pressure jet refrigeration system, which belongs to the technical field of energy and refrigeration. The active balance pressure jet refrigeration system is characterized in that based on the conventional jet refrigeration system, two heat exchangers are increased; refrigerant liquid is preheated by a first heat exchanger 18 or a second heat exchanger 29and then enters a generator 14 so as to prepare working steam; a steam outlet end of the generator 14 is connected with a working steam inlet end of an ejector 1 by a pipeline; hot water enters the generator 14 by a pipeline and then respectively enters the heat exchanger 18 and the heat exchanger 29; the refrigerant liquid in the heat exchanger 18 and the heat exchanger 29 enters the generator 14 by pipelines; and cooling water of a condenser 2 enters the heat exchanger 18 or the heat exchanger 29 by pipelines. The active balance pressure jet refrigeration system of the invention has the advantages of sufficiently recycling solar energy or waste heat of factory production, reducing pre-and-post pressure difference of a liquid pump, improving the working efficiency of the pump and furtherstrengthening the stability of the system operation.

Description

technical field [0001] The invention belongs to the fields of energy technology and refrigeration technology, in particular to an active balanced pressure injection refrigeration system capable of fully utilizing solar energy or production waste heat of factories. Background technique [0002] At present, known refrigeration systems mainly include lithium bromide absorption refrigeration, air refrigeration, vapor compression refrigeration and traditional single-stage injection refrigeration and other refrigeration systems. These systems have been widely used in daily production and life, but there are certain drawbacks and deficiencies. Lithium bromide absorption refrigeration system can be applied to waste heat recovery to achieve energy saving; however, lithium bromide solution has a corrosive effect on pipelines in the presence of air, so regular vacuum maintenance of the system is required, and cooling water and chilled water pipelines should be cleaned in time to preven...

Problems solved by technology

[0005] The purpose of the present invention is to provide an active balanced pressure spray refrigeration system. While inheriting the advantages of the traditional spray refrigeration system, the system adds two heat exchangers, which solves the problem of high pressure difference between the front and back of the pump and saves electric energy.
