Independent Temperature and Humidity Control Air-Conditioning Systems

Abstract

The invention discloses an independent temperature and humidity control air conditioner system. The independent temperature and humidity control air conditioner system comprises an absorption-compression composite refrigerating system, a solution dehumidification circulatory system and a chilled water system. Sensible heat loads and latent heat loads of air can be borne by the absorption-compression composite refrigerating system and the solution dehumidification circulatory system respectively to achieve independent temperature and humidity control over the indoor air. By increasing the evaporation temperature of absorption type refrigeration and enlarging the deflation range of absorption type refrigeration, the absorption type refrigeration cycle energy efficiency ratio is increased. In addition, the absorption-compression composite refrigerating system can reasonably adjust the generation temperature and condensation temperature, reduce the generation pressure and temperature by consuming a small amount of electric energy, decrease the generation temperature on the basis of ensuring the refrigeration effect and enlarges the utilization range of a low-temperature heat source; and meanwhile, a compressor is used for increasing the condensation pressure of the composite refrigerating system to increase the condensation temperature, and all condensation heat is recycled to be used for regenerating a dilute solution of the solution dehumidification circulatory system. The method can decrease the generation temperature of the absorption type refrigerating system, increase the evaporation temperature and greatly improve the system energy efficiency on the basis of ensuring the air conditioning effect.
