| 摘 要： | 介绍一种可以分别采用土壤源或冷却塔＋锅炉作为水源VRV机组冷热源的复合式土壤源VRV试验系统,并分别对该系统的夏季制冷和冬季制热进行测试,比较土壤源VRV工况和冷却塔＋锅炉VRV工况的主机COP,分析土壤源VRV系统的节能性。试验结果表明,土壤源工况时,水源VRV机组的夏季和冬季的主机平均COP分别为6.73和4.01;冷却塔＋锅炉工况时,水源VRV机组夏季和冬季的主机平均COP分别为4.94和4.71。同时分析系统的一次能源利用率,认为定频水泵和天然气耗能较高导致系统PER偏低,为进一步提高土壤源VRV系统的节能性提供指导。

| Abstract: | A hybrid ground-source VRV system which uses ground-source or cooling tower＋boiler as cooling/heating source is presented.Based on the real running data of summer and winter,the unit COP of ground-source VRV system and cooling tower＋boiler VRV system is compared,and the energy-saving property of ground-source VRV system is analyzed.The results show that the average unit COP of ground water-source VRV system in summer and winter are 6.73 and 4.01,and the average unit COP of cooling tower＋boiler water-source VRV system in summer and winter are 4.94 and 4.71.Meanwhile,the primary energy ratio of the system is analyzed,and the results show that the energy consumption of water pump and natural gas of the system is higher.This study will provide some instructions for enhancing the energy-saving of ground-source VRV system. |
