摘 要: 本文基于水制冷剂的性质和蒸发再压缩系统的特点,建立一种用于蒸发的开式水蒸汽再压缩式热泵系统模型;通过对系统循环过程、水的热物理性质、热量传递和功的变化情况的分析,建立了该系统的分析模型;在充分换热的前提下,对不同工况,系统的功耗、换热与能效比等进行了分析计算,得出了系统性能指标的变化规律。 Based on the nature of water refrigerant and the characteristics of vapor recompression system, a open system model of vapor recompression heat pump system used in evaporation is established; Through the analysis of cycle, thermophysical properties of water, heat transfer and power change, a analysis model is established; In the context of full heat, power consumption, heat transfer and COP in different conditions are analyzed and calculated, then we know the relationships of the variation of system performance.
