香港地区溶液除湿与蒸发冷却复合系统的节能分析

Analysis on Energy Efficiency of a Hybrid Liquid Desiccant and Evaporative Cooling System in Hong Kong

本文提出了溶液除湿与蒸发冷却相结合的复合系统,并根据香港地区的气候条件和相关的空调设计参数,将该复合系统的能耗与一次回风空调系统的能耗进行对比。计算结果表明,在设计工况下复合系统的节能率为21.3%,当采用太阳能、地热等可再生能源或其它废热时,系统的节能率更大。结果表明该复合系统在香港具有较好的运用前景。

A hybrid liquid desiccant and evaporative cooling system was presented in this paper. According to the climate conditions and air-conditioning design parameters in Hong Kong, energy consumptions of this hybrid system and primary air system were compared. The calculation results indicated that the energy-saving efficiency of the hybrid system was 21.3 %, and this data could be increased when renewable energy, such as solar energy, geothermal or waste heat,, was used. The comparison results show that hybrid system was valuable in Hong Kong.
