复合式土壤源VRF系统夏季节能特性的实验研究

摘要

详细介绍了系统实验台,并利用该实验台对比分析了冷却塔VRF系统和土壤源VRF系统夏季制冷工况的节能性,得到了两者在夏季制冷运行时部分负荷率下机组EER和系统EER的实际变化规律.冷却塔运行工况下系统EER变化范围为1.19～3.63,地埋管运行工况下系统EER变化范围为1.12～5.4,为复合式土壤源VRF系统的研究和运行策略提供了必要的实验依据.%Describes the system test bed in detail, and compares the energy efficient characteristics of cooling tower VRF system and ground-source VRF system in summer, and finds the actual variation regularity of unit EER and system EER in conditions of partial load ratio. The system EER value varies from 1.19 to 3. 63 in cooling tower conditions, while from 1. 12 to 5. 4 in ground-source conditions, providing necessary experiment references for research and operation strategy of hybrid ground-source VRF system.
