闭式水源热泵空调系统制冷工况分析

Analysis of the Closed Water Source Type Heat Pump Air Conditioning System Under the Refrigeration Condition

介绍了闭式水源热泵空调系统能耗的影响因素,对水源热泵机组定温差、变工况运行时蒸发器侧水温与冷凝器侧制冷剂温度对机组性能的影响进行分析,并根据工程实际对机组性能的数学模型做了修正。

The paper describes the influence factors of energy consumption for air conditioning system of closed water source type heat pump, and analyzes the influence of fixed temperature difference of water source heat pump units end water temperature around evaporator and refrigerant temperature around condense under variable condition runtime on the unit performance. Lastly, it corrects the mathematical model for the unit performance according to the engineering practice.
