Solar-powered high-efficiency moisture absorption-thermochemical reaction single-stage air-conditioning system

Abstract

The invention provides a solar-driven efficient moisture-absorption thermal chemical reaction single-stage air conditioning system which comprises a solar thermal collector, a hot water tank, an absorption thermal chemical reaction air conditioning unit, a cooling tower and an air conditioning terminal. The solar thermal collector is connected with the hot water tank through a pipeline, the hot water tank is connected with the absorption thermal chemical reaction air conditioning unit through a pipeline, and the absorption thermal chemical reaction air conditioning unit is respectively connected with the cooling tower and the air conditioning terminal. According to the solar-driven efficient moisture-absorption thermal chemical reaction single-stage air conditioning system, the circulating moisture absorption amount is improved remarkably, and accordingly energy flow is improved. When the temperature of a heat source is 95 DEG C, the temperature of cooling water is 30 DEG C and the temperature of chilled water is 12 DEG C, and the cold storage density reaches 1.24 kWh / kg; continuous cooling, built-in energy storage and cooling in case of need are achieved, built-in energy storage and cooling are achieved without an external auxiliary energy storage device; in the energy storage process, working medium salt is isolated from a refrigerant and is almost free of loss; in the cold conveying process, the working medium salt is communicated with the refrigerant, the refrigerant undergoes moisture absorption through the cooled working medium salt, and the refrigeration effect is generated.

Description

technical field [0001] The invention relates to the technical field of chloride salt / expanded graphite-water single-stage air-conditioning system, in particular to a solar-driven high-efficiency moisture absorption-thermochemical reaction single-stage air-conditioning system. Background technique [0002] The areas rich in solar energy resources in my country account for more than 67% of the country's land area, and the annual radiation exceeds 6 billion joules per square meter. The annual solar energy absorbed by the surface is equivalent to about 1.7 trillion tons of standard coal energy. 450 times the amount. [0003] However, due to the periodicity, discontinuity and volatility of solar energy, this leads to the instability of solar energy utilization, and at the same time, it is also limited by site, process and other conditions. [0004] Energy storage technology is an effective way to alleviate this problem. Traditional energy storage technologies include sensible he...
