Work and coldness co-production system and method of recovering working medium effective ingredient refrigeration

Abstract

The invention discloses a work and coldness co-production system and a method of recovering working medium effective ingredient refrigeration and relates to the medium and low temperature heat source using technical field. The work and coldness co-production system and the method of recovering working medium effective ingredient refrigeration are driven by medium and low temperature heat source and used ammonia water mixture as a working medium, organically integrates ammonia water working subcycle with ammonia water absorption refrigeration subcycle, achieves co-production of work and coldness, and improves use efficiency of the medium and low temperature source. The work and coldness co-production system and the method of recovering working medium effective ingredient are mainly characterized in that: firstly, gradient use of heat is achieved according to a temperature counterpart principle, a high temperature part of an outer heat source is used for work subcycle, a low temperature part of the outer heat source is used for refrigeration, and working subcycle heat extraction is also used for refrigeration subcycle; secondly, recovering power subcycle can further be used due to ammonia working medium containing turbine exhaust of the recovering power subcycle.

Description

technical field [0001] The invention relates to the technical field of utilization of medium and low temperature heat sources, in particular to a power-cooling cogeneration system and method for refrigeration of recovered active components of the working medium using ammonia-water mixture as the working medium. Background technique [0002] Medium and low temperature heat sources have a wide range of sources and a large number. Today, when energy conservation and emission reduction are vigorously advocated, they have received extensive attention. Medium and low temperature heat sources mainly include two parts: the first is the waste heat discharged in industrial production, such as the exhaust and smoke exhaust of various smelting furnaces, heating furnaces, internal combustion engines and boilers in metallurgy, chemical industry, building materials, machinery, electric power and other industries. Since my country's industrial energy consumption accounts for about two-thirds...
