For the perfomance test of geothermal system, a large pilot of capacity of 50RT is built and operated in office building. This system is planed hybrid system with cooling tower as asisstance heat sink. From October, 2004 to September, 2005, this system is operated and monitored. As the result, COP of heating periods is about 3.46 and COP of cooling periods is about 4.1. Therefore, geothermal system is useful and suitable in Korea.
