Performance simulation of compound solar liquid desiccant air conditioning

In accord with the climatic conditions in hot-humid areas, designs a compound solar liquid desiccant air conditioning system. By establishing a mathematical model, analyses the effects of inlet air parameters of dehumidifier and regenerator on system performance. The results indicate that when dehumidifier inlet air is pretreated from 36 ℃and 80%to 26 ℃ and 90% by cooling and dehumidifying preprocess, the dehumidifier’s volume can be reduced by about 63%, and solution circulating amount about 58%, and that by taking indoor exhaust air as regeneration air, the regeneration efficiency and concentration of liquid can be improved, and the temperature of the regeneration heat source reduced effectively.
