摘要
针对不同热源温度、制热温度、循环倍率及溶液浓度等条件,对以氨水溶液为工质的ACHP系统进行理论分析和热力计算。计算结果表明,利用低温地热尾水为热源的ACHP系统用于提供城市区域供热具有较高的COP和较低的压缩比,并得到ACHP系统热力性能随热源温度、制热温度、溶液浓度、循环倍率变化的趋势,为溶液浓度和循环倍率的优化选择提供理论依据。
Under the different condition, an ACHP system using an ammonia/water mixture as the working fluid had been studied by theoretical analysis and thermodynamic calculation. The results showed that ACHP system with low-temperature geothermal tail water, which was used to provide the urban district heating, had a higher COP and lower compression ratio. And the variation trends of thermodynamic performance along with heat source temperature, heating temperature, solution concentration and circulating ratio were obtained, which would provide the theoretical reference for optimal selection of solution concentration and circulating ratio.
