摘要
为得到中央空调系统中风冷热泵机组的最优化配置方案,本文建立了风冷热泵机组变工况能耗计算模型,根据建筑典型负荷工况、多台机组运行策略、以及机组变工况性能等参数,对风冷热泵机组的技术性、经济性进行了分析。研究结果表明:制热工况下采用多台机组配置方案比制冷工况下采用多台机组配置方案节能效果明显,较常规空调系统配置和方案,全年节约电耗3.4%。
In order to obtain optimal configuration of air- cooled heat pumps in HVAC system, a computing energy consumption model of air- cooled heat pump is developed. Based on typical building dynamic load, multi - unit operation, as well as performance coefficient of air- cooled heat pump on variable condition, authors analyze air- eooled heat pumps＇ economical and technological performance. The results show that multiple air- cooled heat pump working on the heat load condition save energy more than the situation working on the cooled load condition, and compared to conventional air conditioning system configuration, 3.5 % reduction of annual electricity consumption can be achieved.
