Experimental Study On LiCl Liquid Desiccant Air Conditioning System

China is a country with low energy efficiency. Saving energy is a widespread concern. With the popularization of air conditioning systems, energy consumption for building in China is increasing in the total energy consumption. Ordinary air conditioning system controls temperature and humidity by reducing temperature, so it wastes some energy consumption. Thus a new air conditioning system should be developed in order to reduce the energy consumption and improve the air quality.Temperature and humidity independent control air-conditioning system(THAS) puts forward a doable blue print. It controls temperature and humidity separably. The high-temperature chilled water takes on the apparent hot load of air and a new centrifugal fan takes on the latent hot load of air in this system.This paper studies the dehumidified characteristic of solution by experiment. Firstly, diversified means about dehumidify, the dehumidification and the character of dehumidified solution are known. The relative experimental stand is built and chloridized LiCl of different concentration is matched. Secondly, experimental steps about testing the dehumidified performance of liquid are set down after the analysis of the experimental flow. The system tests the dehumidified performance of dehumidification when the inlet air temperature and humidity, the flow of wind and solution change. Finally, the humidity in this system mounts up with the increase of the flow of dehumidified solution and air, the humidity of inlet air and the concentration of solution. Finally, the air-conditioning cooling all-year loads of a commercial building are simulated by DEST in Beijing and Guangzhou. And the energy consumptions are calculated respectively for ordinary air conditioning system and THAS. Compared with ordinary systems, THAS can save about 16.4% of the power consumption per annum; the average coefficient of chiller performance (COP) can increase about 13% in Beijing. THAS can save achieve savings of about 20% of the power consumption per annum, the average coefficient of chiller performance (COP) can increase about 13.5% in Guangzhou. The result shows that THAS is out of the limit of the region and climatic and less energy. Therefore THAS has a better application prospects.
