Solar dehumidification system for underground space

Abstract

The invention discloses a solar dehumidification system for an underground space. The solar dehumidification system comprises a solar heat utilization part, a concentrated solution regeneration part and an underground space dehumidification part. The solar heat utilization part comprises a dilute solution storage tank, a three-way reversing valve, a solar heat collector, a temperature controller and an air source heat pump hot water unit, wherein the solar heat collector is introduced into an open type pulsating heat pipe, so that the temperature of a dilute solution is increased, and water evaporation in the solution regeneration part is promoted; the concentrated solution regeneration part comprises a dehumidification solution regenerator, a first solution pump, a heat regenerator, an air cooler and a concentrated solution storage tank, and the solution concentration is increased by using a flash evaporation technology of liquid dehumidification; and the underground space dehumidification part comprises a second solution pump, a fan, a first temperature detector, a humidity detector, a film type dehumidifier, a third solution pump, a humidity controller and a second temperature detector, and the air humidity is reduced by using a film dehumidification technology. Therefore, the system not only realizes efficient pollution-free dehumidification of the underground space, but also can solve the problems that the regeneration concentration is low and the dehumidified air is easy to carry a dehumidification solution in a liquid solution dehumidification technology.

Description

technical field [0001] The invention relates to the field of new energy utilization, in particular to a solar dehumidification system for underground space. Background technique [0002] With the intensification of urban population density, various cities have experienced land shortage and environmental degradation. In order to alleviate the tension among population, environment and resources, a large amount of underground space has been developed and utilized. Although the underground space has the advantages of warm in winter and cool in summer and open space, due to the particularity of underground engineering, its space is closed and dark, with poor ventilation, and the humid environment is conducive to the reproduction of bacteria and mold. The air quality cannot meet the requirements of human comfort. [0003] The commonly used dehumidification technologies mainly include condensation dehumidification, solid dehumidification, liquid dehumidification and membrane dehu...
