Abstract
A water-to-water heat pump, using low temperature geothermal water, was applied to heating and air-conditioning for a hotel. In winter, the heat pump extracted heat from geothermal water between 13~18ºC and provided water between 40~45ºC; in summer, the heat pump discharged heat to geothermal water between 13~16ºC and provided water between 7~10ºC. The economic and environment profits are discussed, and it is indicated that heating and air-conditioning with heat pumps using low temperature geothermal water not only saves basic energy but also protects the environment.
