Abstract
A water-to-water geothermal heat pump running on R-22 was applied to recover heat energy from low temperature geothermal energy for heating and air-condition for a hotel which area is 6000m2. The heat pump used geothermal water between 13~18? and provided water between 40~45? in winter, and used geothermal water between 13~16? and provided water between 7~10? in summer. The economics and environment effects are discussed. It is indicated that using low temperature geothermal water through a heat pump to heat and refrigerate saves basic energy and protects the environment.
