摘要
对地下水源热泵系统中蒸发器、压缩机、冷凝器、节流阀及系统进行了火用分析,给出火用效率、单位时间火用损、火用损系数的计算公式。结合工程实例,对某地下水源热泵系统进行了火用分析,压缩机的单位时间火用损最大。
The exergy analysis of groundwater source heat pump system as well as the evaporator, compressor, condenser and throttle valve in the system is carried out, and the calculation formula for ex- ergy efficiencies, exergy loss per unit time and exergy loss coefficient is given. Taking engineering for example, exergy analysis of a groundwater source heat pump system is conducted, and the exergy loss of the compressor per unit time is maximum.
