Absorption refrigeration and solution dehumidification air-conditioning system based on solar heat recovery

Abstract

The invention provides an absorption refrigeration and solution dehumidification air-conditioning system based on solar heat recovery which integrates solar heat recovery, absorption refrigeration and solution dehumidification. Heat recovered by a solar heat collector is used for absorption refrigeration and solution dehumidification; refrigerant water prepared by an evaporator is used for cooling down a concentrated solution in a solution dehumidifier; outdoor fresh air is directly contacted with the concentrated solution after recovering the refrigerating capacity of indoor exhaust air so as to conduct heat and humidity exchange, and after the dehumidification and temperature reduction, the outdoor fresh air is fed into a room from the side wall at the upper part of the room to form a wall attached jet; the air jet continues heat exchange for temperature reduction with a radiant cooling panel at the top of the room; and finally the temperature and humidity conditions of the room are achieved and the independent control on the temperature and the humidity of the room is accomplished.

Description

technical field [0001] The invention belongs to an absorption refrigeration and solution dehumidification air conditioning system based on solar heat recovery, which integrates solar energy recovery, absorption refrigeration and solution dehumidification. Background technique [0002] At present, most of the air-conditioning technologies are powered by electricity and rely on fluorides such as Freon as the refrigeration cycle medium to absorb indoor heat and discharge it to the outdoors. This traditional compression air-conditioning technology has the following shortcomings: firstly, the problem of energy consumption is serious; secondly, the extensive use of fluorides such as freon has caused the destruction of the atmospheric ozone layer and deteriorated the ecological environment; thirdly, it is discharged to the outside The heat increases the atmospheric temperature of the city, making the heat island effect intensified. [0003] Solar energy is an inexhaustible, inexha...

AI Technical Summary

Problems solved by technology

This traditional compressed air conditioner technology has the following disadvantages: one, serious energy consumption problems; two, the extensive use of fluorides such as freon, has caused the destruction of the atmospheric ozone layer and deteriorated the ecological environment; three, discharged to the outside The heat of the city increases the atmospheric temperature of the city, exacerbating the heat island effect

The solar liquid dehumidification air-conditioning system can directly absorb water vapor in the air, which can avoid the compression air-conditioning system in order to reduce the humidity of the air, first of all must cool the air below the dew point, resulting in a decrease in system efficiency
