【摘要】：建立空气源热泵与小型固体除湿转轮相结合的复合机组,利用压缩机的高温排气和冷凝热作为转轮除湿剂的再生能源,并应用于新风量较小、湿负荷较低的居住建筑。对热泵的排气温度与能量利用特性进行分析并对热泵废热利用情况下的除湿转轮进行模拟与实验研究,结果表明在夏季冷却除湿工况下,热泵系统的废热足够实现除湿转轮的再生并满足室内湿负荷的要求。将复合机组的一次能源利用率与传统系统进行对比,在冬季工况下,复合机组的一次能源利用率相较于空气源热泵高25%;在夏季工况下,复合机组的一次能源利用率相较于空气源热泵高36%。
[Abstract]:The combined unit of air source heat pump and small solid desiccant runner is established. The high temperature exhaust and condensing heat of compressor are used as regenerative energy of dehumidifying agent of rotary wheel, and it is applied to residential buildings with low fresh air volume and low wet load. The exhaust temperature and energy utilization characteristics of heat pump are analyzed, and the dehumidification runner under the condition of heat pump waste heat utilization is simulated and experimentally studied. The results show that under the condition of cooling and dehumidification in summer, The waste heat of heat pump system is enough to realize the regeneration of desiccant runner and meet the requirement of indoor wet load. Comparing the primary energy efficiency of the composite unit with the traditional system, the primary energy efficiency of the composite unit is 25% higher than that of the air source heat pump in the winter condition, and in the summer condition, the primary energy efficiency of the composite unit is 25% higher than that of the air source heat pump. The primary energy efficiency of the composite unit is 36 times higher than that of the air source heat pump.
