Solar heat collection comprehensive utilization system

Abstract

The invention discloses a solar heat collection comprehensive utilization system. A hot water outlet of a solar collector is respectively communicated with hot water inlets at input ends of two water-water heat exchangers; a cold water inlet of the solar collector is respectively communicated with cold water outlets at the input ends of the two water-water heat exchangers; a hot water outlet of the output end of one water-water heat exchanger A is communicated with a water outlet of a normal-temperature water supply pipe of an external boiler, and a hot water outlet of the output end of the water-water heat exchanger A is communicated with a water inlet of the normal-temperature water supply pipe of the external boiler; and a cold water inlet of the output end of the other water-water heat exchanger B is connected with a water outlet of a hot water circulating pipe of a lithiumbromide absorption refrigerating machine, and a hot water outlet at the output end of the water-water heat exchanger B is connected with a water inlet of the hot water circulating pipe of the lithiumbromide absorption refrigerating machine. Compared with the prior art, the solar heat collection comprehensive utilization system has the advantages of improving work efficiency of an industrial hot water boiler or the lithiumbromide absorption refrigerating machine and saving energy.

Description

technical field [0001] The invention relates to a comprehensive utilization system of solar energy, which is a system for comprehensive utilization of solar energy by utilizing a large-area solar heat collector, a water-water heat exchanger and a lithium bromide refrigeration unit. Background technique [0002] At present, although there are many systems using solar energy, some of them have low efficiency, and some only use solar energy to collect heat, and use solar heat to obtain hot water, refrigeration and other single small civil systems, and there are few industrialized comprehensive utilization, especially for some industrial hot water. The boiler is directly fed with water at a temperature of about 15 degrees, which not only consumes more energy such as coal, electricity, gas, oil, etc., but also lowers the working efficiency of the boiler. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and...
