Independent temperature and humidity control air conditioner system

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.

technical field [0001] The invention relates to an air-conditioning system with independent temperature and humidity control based on absorption-compression composite refrigeration and solution dehumidification, belonging to the technical field of refrigeration and air-conditioning systems. Background technique [0002] At present, the most common air-conditioning method is to use vapor compression refrigeration, which uses a compressor as power to transfer indoor heat to the outdoors by changing the pressure of Freon and other refrigerants to complete the cooling. This traditional vapor compression refrigeration technology has been widely used for its advantages of flexibility, convenience, small size and high efficiency. However, with the increasing energy consumption and ensuing environmental problems, vapor compression refrigeration has also exposed Some defects are mainly as follows: First, it consumes a large amount of high-grade electric energy, and the primary energy...
