Abstract

The invention discloses a medium-high temperature solar steam-absorption refrigeration-seawater desalination-energy storage coupling system. The system takes heat-conducting oil and water/steam as heat-transfer fluid, and takes phase transition metal and water steam as heat storage media. The system comprises a solar collector system, a heat transfer working medium circulating system, an absorption refrigeration system and a seawater desalination system, and comprises a parabolic groove-type optical collector (1), a phase transition metal energy storage tank (2), a heat conducting oil-steam generator (3), an oil source absorption refrigeration unit (4), an oil source seawater desalination unit (5), a high-temperature oil pump (6), an electric three-way adjustment valve (7), a steam heat storage device (8), a steam source absorption refrigeration unit (9), a steam source absorption refrigeration unit (10), a water treating device (12), a Fresnel plane reflecting mirror (13), an energy-storage absorber (14), a cooling medium inlet valve (16), a cooling medium outlet valve (15), a fresh water outlet valve (18), a seawater inlet valve (19) and the like. By the system, high-temperature heat-conducting oil and steam can be acquired; and the system is suitable for the coupling of large-scale seawater desalination and absorption refrigeration.

Description

technical field [0001] The invention relates to a medium-high temperature solar heat utilization coupling system, in particular to a medium-high temperature gradient utilization solar system coupled with steam-absorption refrigeration-seawater desalination-energy storage. Background technique [0002] With the development of my country's economy, environmental pollution is becoming more and more serious and fossil fuels are decreasing year by year. The solution to energy and fresh water problems is the key to realizing my country's "energy saving and emission reduction, and building a conservation-oriented society". my country has a long coastline and abundant seawater resources. Seawater desalination technology can be used to desalinate seawater to meet people's needs for fresh water in life and industry. At the same time, our country is rich in solar energy resources, and has made great achievements in the low-temperature solar thermal benefit. It has become the world's la...
