摘要
针对校园建筑中水源热泵能源站系统的夏季运行特性展开实验研究,分析了以冷却塔为释热源时机组运行时间、蒸发侧和冷凝侧的水流量以及不同主机负荷对机组和系统能效比以及系统运行效果的影响,了解系统的运行规律。研究结果表明,在系统的制冷量满足设计要求情况下,冷冻水流量最佳范围在205-210 m^(3)/h,冷却水流量最佳范围在180-185 m^(3)/h,机组COP能达到最大值6.1,系统COP能达到最大值4.7;与传统壁挂式空调相比,水源热泵能源站每天可以节能24.2%,具有良好的应用前景,可以在集中供冷、供暖建筑中推广使用。
In this paper,the summer operation characteristics of water source heat pump energy station system in campus buildings are studied experimentally.The influence of unit operation time,water flow of evaporation side and condensation side and different host load on unit and system energy efficiency ratio and system operation effect are analyzed when cooling tower is used as heat release source.The results show that the optimal range of chilled water flow is 205 when the cooling capacity of the system meets the design requirements In the range of 180〜210 m^(3)/h,the best cooling water flow range is 180〜185 m^(3)/h,the unit cop can reach the maximum value of 6.1,the system cop can reach the maximum value of 4.7;compared with the traditional wall mounted air conditioning,the water source heat pump energy station can save energy by 24.2% every day,which has a good application prospect,and can be widely used in central cooling and heating buildings.
