Solar air pretreatment staged solution heat collection regeneration device

Abstract

The invention relates to a solar air pretreatment staged solution heat collection regeneration device which comprises an air circulation loop and a solution circulation loop. The device has the following technical effects: 1) utilizing the high-efficient regeneration of a first-stage heat collection / regenerator to carry out compensation on the low-efficient regeneration of a second-stage heat collection / regenerator; 2) utilizing outdoor air to carry out the first-stage regeneration on low-concentration solution, and then using the low-concentration solution after the first-stage regeneration to carry out pre-dehumidification on the outdoor air, wherein the dry air after the dehumidification can realize the effective regeneration of high-concentration solution in the second-stage heat collection / regenerator and improve the energy storage capacity of the high-concentration solution; and 3) the prominent advantage of the solar air pretreatment staged solution heat collection / regeneration device is the effect of improving the water evaporation rate of the high-concentration solution by sacrificing the water evaporation rate of the regeneration of the low-concentration solution under the conditions of high humidity and low solar radiation, thereby being particularly applicable to areas having the weather with high humidity in southern China.

Description

technical field [0001] The invention relates to a novel solar energy dehumidification solution regeneration device, in particular to a solar energy air pretreatment graded solution heat collection regeneration device. Background technique [0002] At the Copenhagen Climate Conference, the Chinese government proposed that by 2020, the GDP per unit will drop by 40%-45% compared to 2005, and building energy-saving technology will be the focus of my country's scientific and technological research and development in the future. Solar solution dehumidification and refrigeration technology will be an important technology to replace traditional compression refrigeration because it can use low-temperature heat sources such as solar energy and industrial waste heat for solution regeneration, and has energy storage characteristics. Its promotion and application will greatly reduce the energy consumption level of existing buildings, reduce carbon emissions, and alleviate the atmospheric...

AI Technical Summary

Problems solved by technology

However, the high-humidity and low-radiation weather in southern my country will have a great adverse effect on the heat collection / regeneration performance of solar solutions, because the regeneration temperature of high-concentration solutions must be kept at a high level in such weather, which will reduce the regeneration efficiency of solar solutions.
