摘要
基于工程实践,在一定的技术背景条件下,对污水源热泵系统的制热、制冷工况及特征参数做了全面测试,包括供暖空调效果、水源侧运行参数、系统能耗水平、典型工况等,得到各类运行参数特性曲线.研究表明,热泵系统运行效果良好,水源侧温度保持在7℃以上,全系统制热系数大于3.5,制冷系数大于4.0,典型水源工况为7.5～3℃.对污水源热泵系统设计与评价有参考意义.
From the engineering practice, under some technology background, the characteristic parameters of heating and refrigeration status was roundly tested, including the heating or air condition effect, the wastewater＇ s parameters, the system＇ s energy wasting level, typical work status. The characteristic curves of each work parameter was given out. The study indicated that the work effect is good and the wastewater＇ s temperature is above 7℃, the heating COP is above 3.5, the air condition COP is above 4.0, the typical wastewater temperature was 7.5 - 3℃. It＇s useful for designing or evaluating the wastewater source heat pump.
