膜式溶液除湿空调与二氧化碳跨临界循环热泵一体化系统性能研究
A Performance Study of Membrane Liquid Desiccant Air Conditioning System and Carbon Dioxide Transcritical Cycle Heat Pump Integrated System
摘要
Abstract
The direct contact liquid desiccant air conditioning driven by heat pump with freon as working fluid has the problem of air carrying desiccant solution, and this kind of working fluid is likely to destroy the environment. So an integrated system of membrane liquid desiccant air conditioner and carbon dioxide transcritical cycle heat pump system is presented, and the theoretical model of the system is established. The application of this system in a hotel in Guangzhou and the simulation analysis show that the integrated system performance coefficient EER is 8.8 and 0.65 for dehumidification efficiency. In full load condition, the design and performance difference of the"integrated system and dry air filter system of dry fan coil" and the "traditional fan coil and fresh air conditioning system" are compared and analyzed. The total power of the main equipment of the "integrated system and dry air filter system of dry fan coil" and the "traditional fan coil and fresh air conditioning system" are 74.3 kW and 90.5 kW, respectively. The air conditioning system based on the concept of THIC is 21.3％ lower than the traditional fan coil plus fresh air conditioning system of electric power.关键词
