摘要：
设计了一种带过热蒸气热回收装置的地下水地源热泵系统实验装置。在设定工况（冷却水进出口温度18 ℃/26 ℃，冷水进出口温度12 ℃/7 ℃，生活热水流量750 L/h）下，研究了增设热回收装置对压缩机吸排气温度、冷凝温度以及蒸发温度的影响。结果表明，与不带过热蒸气热回收地下水地源热泵系统相比，系统运行稳定性良好，运行工况得到明显改善。
Abstract：
Designs a groundwater source heat pump (GWHP) experimental apparatus with superheated vapor heat recovery. For the setting working condition (the inlet and the outlet temperatures of the cooling water are 18 ℃ and 26 ℃respectively, the inlet and the outlet temperatures of the chilled water are 12 ℃ and 7 ℃ respectively, and the domestic hot water flow rate is 750 L/h), studies the effects of the superheated vapor heat recovery apparatus on the suction and discharge temperature of the compressor, the evaporation temperature and the condensation temperature. The results show that compared with the GWHP without superheated vapor heat recovery, this system has better operating stability and the operating condition has been further improved.
