This research has developed a GWHP system that employs a hybrid heat pump system with groundwater wells using multi heat source, groundwater and air source. This paper describes about real-scale experiments using a standing column well (SCW). The heating and cooling experiments have been conducted at Nagoya site where the groundwater level is 4 m depth and the quality of groundwater is not good. The SCW has two screens which divided by a packer and the system can automatically switch the positions of pumping and returning. The coefficient of performance (COP) of heat pump and system was calculated by the temperature of groundwater and the pumping rate. In the results, system COP of cooling was 6.5 and it of heating was 3.6.
