Study On The Dehumidification, Regeneration And Cleaning Properties For A New Solar Dehumidification And Cleaning Window

The South of China is abundant rainfall, perennial damp, especially in the rainy season the southern areas are in the wet state.The hot and humid climate environment not only bring a lot of inconvenience to work, life and production, but also increase the energy consumption of air conditioning systems. At the same time, the haze weather in our country has been showing explosive situation in large scale, top of 500 cities in China, less than 1% meet air quality standards recommended by the World Health Organization, there are ten most polluted cities in the world and China accounted for seven.In view of the present existence environment humidity is serious, poor air quality, and high energy consumption of building, this paper is designed and developed a suitable for civil construction and use solar energy regeneration of the dehumidification purification window directly. The device with three layers solid desiccant silica gel thin bed as desiccant layer and the two layers of HEPA efficient filter paper as purifying layer, combining with the double glass windows and using solar energy for regeneration of desiccant layer after moisture absorption. Through the establishment of experimental test platform for a new clean solar desiccant dehumidification performance of windows, the regeneration performance, auxiliary regeneration methods and purification performance test study, the results of the study can provide the basic experimental basis for the engineering application.Dehumidification performance test, including the water condensation rate effective dehumidification time, dehumidification efficiency, import and export air temperature as well as the weighing method was compared with the calculation method of five aspects. When the desiccant bed was finished the process of absorption, it would be regeneration by four ways that including pure radiation regeneration, radiation+ ventilation regeneration, radiation+air exhaust and radiation+desiccant-wheel based exhaust regeneration. And respectively for four regenerative ways to experiment and theoretical study.The new clean solar desiccant purification window on solid particles of air PM2.5 particles levels of good purification effect is the average purification rate reached 47.50%, and the purification efficiency of decline is not obvious with the time.Considering the limitation of direct solar radiation regeneration, the paper is also compared the regeneration effect of two kinds of regenerative ways include of the microwave regeneration and hot air regeneration through the experiment, the results show that the regeneration of the regeneration time, regeneration efficiency and the energy consumption features are better than the hot air regeneration.At the same time, according to the relevant knowledge dehumidification purification window energy balance calculation model is established, and the established calculation model for the theoretical calculation of performance. Desiccant layer temperature and the analysis of the results of theoretical calculation and experimental test. The results show that the theoretical calculation curve and test curve was consistent, the theory established model can be applied with such devices in the analysis.
