Abstract

An underground temperatures renewal type geothermal heat pump system is a System which installs geothermal exchanger into the perpendicular hole excavated from surface of the earth to near 30 lower m, and extracts underground heat.<BR>It sets up the interval of about 1∼1.5 m for the purpose of preventing between geothermal exchangers interfering in this System mutually with heat. When continuing taking heat from the underground between long times, geothermal efficiency falls. In that case, it operates the storage pump prepared near the geothermal exchanger, and make groundwater near the geothermal exchanger flow compulsorily.<BR>If a coercive flow of groundwater takes place, the underground temperatures near geothermal exchanger will be improved and geothermal efficiency will go up.
