Solar energy driven recuperative solid drying and dehumidifying air conditioner system and running method

Abstract

The invention discloses a solar energy driven recuperative solid drying and dehumidifying air conditioner system. The solar energy driven recuperative solid drying and dehumidifying air conditioner system comprises a first dehumidifying heat exchanger and a second dehumidifying heat exchanger, wherein the first dehumidifying heat exchanger and the second dehumidifying heat exchanger are set to work simultaneously so as to realize continuous running of the system. In a dehumidifying process, cooling water generated by a cooling tower is fed into the first dehumidifying heat exchanger, and takes away adsorption heat generated in an adsorption dehumidifying process of a drying agent; and meanwhile, hot water from a recuperative water tank is fed into the second dehumidifying heat exchanger at first for a period of time, then hot water of a thermal-insulation water tank of a solar thermal collector is fed into the second dehumidifying heat exchanger, the drying agent is desorbed and regenerated by the hot water, and produced regenerated air heats the hot water in the recuperative water tank. The solar energy driven recuperative solid drying and dehumidifying air conditioner system has the advantages of simple structure, easiness in operation, low cost, low investment and the like; and the regenerated air with high temperature and high humidity can be utilized efficiently, the efficiency of the integral system is greatly improved, and thermal pollution of the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning, in particular to a solar energy-driven heat recovery type solid drying dehumidification air conditioning system and an operating method. Background technique [0002] In recent years, with the improvement of people's living standards and the frequent appearance of extreme environments around the world, the widely used traditional vapor compression heat pump air-conditioning system has become the main source of electricity consumption in the whole society. Recently, solid dry dehumidification air-conditioning technology has been widely researched due to its advantages of resource saving and environmental friendliness, and it is considered that it can replace traditional compression air-conditioning in future development research. The composite of the air conditioning system includes two aspects of sensible heat load (heat load) and latent heat load (humidity load). Amon...

Problems solved by technology

Research on independent control of temperature and humidity by using a desiccant-attached desiccant heat exchanger instead of a dehumidification wheel has also emerged, but the overall efficiency of the system is not high, and the high-temperature and high-humidity regeneration air generated during the regeneration process is directly discharged into the atmosphere. On the one hand, it causes energy waste, and on the other hand, it causes certain thermal pollution to the atmospheric environment.

[0004] After searching the public literature of the prior art, it was found that the Chinese patent application number is CN201210232592 "self-cooling solid desiccant cooling dehumidification air-conditioning system" patent, which provides a self-cooling solid desiccant for the shortcomings of the traditional solid dehumidification air-conditioning system Although the cooling and dehumidification air conditioning system uses the refrigerated water produced by the evaporative cooler to solve the problem of adsorption heat in the dehumidification process, the high-temperature and high-humidity regeneration air generated during the regeneration process is not treated, which not only wastes energy but also causes certain thermal pollution to the environment
