STUDIES ON THE REFRIGERATING PERFORMANCE OF THE GROUND HEAT PUMP WITH U-SHAPED VERTICAL LOOP PIPE IN QINGDAO, CHINA

摘要

The first experimental device of the Ground Heat Pump with U-shaped vertical loop of pipe system in Qingdao, China was described. Studies on supplying cooling with this device were carried out and much data on the refrigerating performance were obtained. The relation of the refrigerating capacity with the length of U-shaped vertical loop of pipe and the empirical equation of the refrigerating coefficient of performance (RCOP) were discussed in this study.
