基于热泵驱动的新型溶液除湿空调系统

New Liquid Desiccant Air Conditioning System Driven by Heat Pump

常规的热湿耦合处理空调系统由于所需的除湿温度低,导致制冷效率低、冷热抵消、自然冷源无法应用以及室内空气品质较差等问题。热泵驱动的新型溶液除湿空调系统就是在这一背景下提出来的,它具有运行稳定、高效节能等优点,是未来理想空调的一个新的发展方向。这种新型溶液除湿空调系统,利用冷凝器释放的冷凝热作为稀溶液再生热源。利用双冷凝器并联运行,并结合空气源或水源等冷热源方式实现制冷系统的热量平衡,充分发挥常规冷凝温度制冷循环在制冷能效方面的优势。对青岛一座四层综合楼的能耗计算表明,基于热泵驱动的新型溶液除湿空调系统比常规热湿耦合处理空调系统节能约22.2%。

Some problems such as low cooling efficiency,cold and heat offset,inability to apply natural cold sources,and poor indoor air quality are leaded by the low dehumidification temperature required of conventional heat and moisture coupling processing air conditioning system. For resolving these problems,a new liquid desiccant air conditioning system driven by heat pump is proposed,which runs well and saves energy. It represents a new development direction of ideal air conditioning. The condensation heat released by the condenser is used in the new liquid desiccant air conditioning system as the heat source for dilute solution regeneration. However,double condensers running in parallel are used to balance heat of the refrigeration system by combining the air source or the water source according to local conditions,and are good at giving full play to the advantages of the conventional condensing temperature refrigeration cycle in terms of refrigeration energy efficiency. The energy consumption calculation of a four-storey complex building in Qingdao shows that the new liquid desiccant air conditioning system can save about 22.2% energy compared with the conventional heat and humidity coupled treatment air conditioning system.
