The major investigation is to utilize the theory of de-humidification in different ways from traditional design of condensing dehumidification. A liquid desiccant system coupling with heat pump will be researched and developed. The features of the proposed system are (1) liquid desiccant dehumidification, (2) liquid desiccant regeneration by the condenser heat of heat pump, (3) enhanced dehumidification by the cooling capability of heat pump. The saturation vapor pressure of strong solution surface is lower than the water vapor pressure of ambient air. The vapor pressure difference will be the driving force to diffuse the water molecular. Then, the strong solution becomes the weak solution. The regeneration air will contact with the weak solution, and the weak solution will be heated. The saturation vapor pressure of weak solution surface becomes higher than the water vapor pressure of ambient air, and the water molecular will diffuse from the solution to the air. The condenser heat of heat pump is the heating source in this study, and the cooling energy produced by the evaporator of heat pump is to enhance the dehumidification performance of liquid desiccant. The evaporating temperature of heat pump can be higher to increase the COP of heat pump because the system is chemical dehumidification. At the same time, the chilling system can reduce the loading because the latent load is eliminated. Hence, the power consumption for operating air-conditioning system will decrease significantly. Theoretic analysis and experimental study are all the researching methodologies, and an experimental platform of 2,000 m3/hr air supply capacity will be set up. Experimental testing will be proceeded to gather the performance data of the proposed system. Results of theoretic and experimental analysis will be verified by each other.熱泵液體除濕空調箱heat pumpliquid desiccantAHU耦合熱泵之液體除濕系統
