【英文篇名】 Testing of ground water source heat pump systems in summer 【作者中文名】 刘雪玲; 朱家玲; 雷海燕; 【作者英文名】 By Liu Xueling★; Zhu Jialing and Lei Haiyan★Tianjin University; Tianjin; China; 【作者单位】 天津大学; 【文献出处】 暖通空调, Journal of Heating Ventilating 低品位地热资源; 空调; 经济分析; 【英文关键词】 ground-source heat pump; low temperature geothermal; air conditioning; economic analysis; 【摘要】 对地下水地源热泵系统夏季空调工况的可行性进行了测试和分析,结果表明夏季供冷时,室内温度可维持在25.5℃左右。若生产井和回灌井的距离较近,随着供冷期天数的增加,抽水井温度呈上升趋势,故应适当增大两井的距离。经济性分析表明热泵用于夏季空调工况的运行费用很低,但初投资较大。 【英文摘要】 Tests and analyses the operating condition of a ground water source heat pump system in summer. The results indicate that the temperature of the room is about 25.5 ℃. If the production well is close to the injection well, the temperature of the production well rises with the cooling time, so the distance of the two wells should be increased. Economic analysis results show that the operating cost of the heat pump system is cheap, but the initial investment is high.
