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%。
In this paper, an air-source heat pump combined desiccant wheel air-conditioning system was established, which uses exhaust heat of compressor and condenser heat as a renewable energy of desiccant wheel. And it was applied to residential buildings whose fresh air load and wet load is small. Simulation analysis of heat pump and simulation and experiment analysis of desiccant wheel with waste heat recover of heat pump showed that heat pump is sufficient to achieve the regeneration of desiccant wheel and meet the requirements of indoor moisture Load, during the summer cooling and dehumidifying conditions. Compared with conventional system, primary energy ratio of this hybrid system can increase 25% and 36%, respectively in winter and summer for the air-source heat pump.
