Abstract

The invention relates to a solar-driven efficient moisture absorption-thermal chemical reaction two-stage air conditioning system. The system comprises a left high-temperature adsorption bed (1), a left low-temperature adsorption bed (9), a left condensation evaporator (11), a right high-temperature adsorption bed (15), a right low-temperature adsorption bed (23) and a right condensation evaporator (25). The whole circulation process comprises absorption, crystallization and a thermal chemical reaction of moisture absorption salt. Compared with the prior art, a chlorate / expanded graphite-water two-stage mode is adopted, continuous cold supply can be achieved through the whole circulation process, internal energy storage can be achieved as well, an external auxiliary energy storage device does not need to be additionally arranged, energy loss is small, and energy storage efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and relates to a solar-driven high-efficiency moisture absorption-thermochemical reaction two-stage air-conditioning system. Background technique [0002] The areas rich in solar energy resources in my country account for more than two-thirds 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 total consumption. [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 are sensible heat storage (such as water and stones) and latent heat...
