高校洗浴用水水源热泵系统节能分析

Energy Conservation Analysis of Water Source Heat Pump System Using Bath Water in a University

以高校洗浴中心的供水、排水作为水源热泵机组的循环水,采用实测与对比方法分析了该热泵系统的节能性.夏季,热泵系统以城市管网供水作为冷凝器冷却水,并把加热后的水送往洗浴中心,节约能源相当于59.15吨标准煤.冬季,以洗浴排水作为热泵蒸发器循环水,把回收到的低位热能用于建筑采暖,形成了供冷、供暖及供热水三功能组合,可节约标准煤51.64吨.并且,该水源热泵机组提高了制冷系数与制热系数,节约了高品位能源.

Supply and discharge bathing waters in a university bath center were used as circulation water of water source heat pump system,and the energy conservation of this heat pump system was investigated and analyzed.In summer,the city tap water was used as cooling water in heat pump condenser,the heated water was transported to the bath center,and the energy conserved by this system reaches to 59.15 tons of standard coal.In winter,the discharge bathing water was used as circulation water in heat pump evaporator,and the low-grade heat of waste bathing water was recovered to supply for buildings.The tri-function system including heating,refrigerating and supplying hot water could conserve energy about 51.64 tons of standard coal.The refrigerating and heating coefficients of the system were improved,and high-grade energy was well conserved.
