Abstract

The invention relates to a solar-powered efficient moisture absorption-thermochemical reaction heat pump system. The solar-powered efficient moisture absorption-thermochemical reaction heat pump system comprises a solar heat collector (1), a hot water tank (7), an absorption-thermochemistry heat pump set (37), an evaporator (55), a heat supply tank (61) and a heating pipe (65). The absorption-thermochemistry heat pump set comprises a left absorption bed (30), a left condenser (32), a left evaporator (35), a right absorption bed (31), a right condenser (34) and a right evaporator (36). A circulation process comprises the steps of absorption of moisture absorption salt, crystalalization of the moisture absorption salt and a thermochemical reaction. Compared with the prior art, the solar-powered efficient moisture absorption-thermochemical reaction heat pump system can realize continuous heat supply and built-in type energy storage, heat supply is conducted only when needed, and built-in type energy storage and heat supply can be realized without additionally arranging an external auxiliary energy storage device; in the energy storage process, the working medium salt and refrigerant are mutually isolated, and loss is barely caused.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and relates to a solar-driven high-efficiency moisture absorption-thermochemical reaction pump system. Background technique [0002] my country is a country rich in solar energy resources. Two-thirds of the country's land area has an annual sunshine of more than 2200 hours, and the total annual radiation is about 3340-8360MJ / m per year. 2 , equivalent to 110-250kg standard coal / m 2 . [0003] However, solar energy has its own inherent disadvantages. For example, the intensity of solar energy is weak, and the energy density obtained from the ground is low, so it cannot be directly applied. If higher energy density is required, a collector with a high focusing ratio must be used. In addition, solar energy is unstable, it is not only affected by day and night, season, latitude and altitude, but also by weather. Therefore, in order to make solar energy a continuous and stable en...
