The present invention relates to improvement of cooling efficiency of a geothermal heat pump, wherein underground temperature is constant and the efficiency is decreased when soil constantly receives heat of a high temperature in extremely hot weather, by installing an ice storage facility in a building basement and applying the ice storage facility to a geothermal heat pump system. According to the present invention, the heat discharged from the inside of a building is firstly absorbed using ice of a storage tank in which the ice is stored. Air absorbing heat secondarily flows in the ground so the heat is finally absorbed. The air which is cold as the heat is absorbed flows to an inner heat exchanger and is heat-exchanged so that the cold air flows inside the building. According to the present invention, the geothermal heat pump discharges indoor heat after two stages so the geothermal heat pump provides economical efficiency for a user of the building and obtains energy reducing effect. |
