摘要
介绍了青岛地区首台U型垂直埋管式土壤源热泵实验系统 ,通过对热泵制冷工况的实验研究 ,得出制冷量与U型垂直埋管长度间的关系 ,并回归出热泵的制冷性能系数经验公式。
describes the experimental device of the ground heat Pump with U-shaped vertical loop of pipe.the tests on supplying cooling are carried out and much data of refrigerating performance are got from the experiment.the relationship of refrigerating capacity to the length of U-shaped vertical loop of pipe and the empirical equation of COP are determined through data process.
