Problems solved by technology

However, when the water vapor content in the air is high, the adsorption rotor needs to consume a lot of heat. Unless the "free" renewable energy is used, the overall coefficient of performance of the system is lower than that of the traditional refrigeration method, and the energy saving cannot be achieved.

Abstract

The invention discloses a dehumidification air cooling apparatus and a cooling method. The dehumidification air cooling apparatus comprises an air dehumidification device provided with a moisture adsorber, wherein an air outlet of the air dehumidification device is connected with a cooling device, and the air dehumidification device is further connected with an adsorber regeneration device used for regenerating the moisture adsorber after excessive moisture is adsorbed by the moisture adsorber. The water vapor content of air in an external environment is reduced through the air dehumidification device, and then the air exchanges heat with cooled air flowing through a cold-side channel of an indirect evaporative cooler to achieve the purpose of dehumidifying and cooling the cooled air, and meanwhile, the cooled air enters a direct evaporative cooler to further achieve the required temperature and humidity. According to the invention, the techniques of membrane separation and adsorption are combined together, and an evaporative cooling technique is adopted to cool and absorb heat, so that a system can work in a high-humidity environment, the integrated energy efficiency ratio is high and the maintenance workload is small.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and membrane separation, and relates to an air cooling device, in particular to a dehumidifying air cooling device and a cooling method. Background technique [0002] The cooling and adjustment of air is a necessary means to improve people's living environment or ensure the normal operation of equipment. Usually, forced ventilation or appropriate refrigeration technology can be used to achieve it. However, the former is mainly determined by the external environment and cannot be fundamentally solved. The latter is the main method used in air conditioning at present. The common ones are the mechanical compression refrigeration method using freon working fluid, the absorption or ejection refrigeration method driven by heat energy, but these methods all have the disadvantages of large energy consumption or difficult maintenance. shortcoming. [0003] With my country's emphasis on low-carbon...
