【摘要】 研究了湖水源热泵系统尾水射流式、表面式和淹没式3种排放方式,以及上述三种排放方式下单口、双口和穿孔管横向分散3种出流方式对湖泊局部水域温升分布的影响,探寻对湖泊水环境影响较小的尾水排放方式。采用权值平均法对试验结果进行评价优选,得出对湖泊水环境温升影响较小的排放方式有:穿孔管横向分散出流射流排放、穿孔管横向分散出流表面排放、穿孔管横向分散出流淹没排放、双口出流射流排放,其中穿孔管横向分散出流射流为最优排放方式。更多还原

【Abstract】 Three discharge modes of tail water from lake water-source heat pump system,including jet-type,surface-type and submerged-type discharge and their flow modes including single port,double port and perforated pipe horizontal dispersion port were simulated to investigate their influence on the temperature rise distribution in the local lake water area.The discharge mode with less influence on the lake water environment was studied.The experimental results are evaluated and optimized by weighted average method.The discharge modes with less influence on the lake water environment are jet-type discharge with perforated pipe horizontal dispersion port,surface-type discharge with perforated pipe horizontal dispersion port,submerged-type discharge with perforated pipe horizontal dispersion port and jet-type discharge with double port.The jet-type discharge with perforated pipe horizontal dispersion port is the best.更多还原
