香港地区溶液除湿与蒸发冷却复合系统的节能分析

Abstract

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2.3%,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 2.3%,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.
