| 摘要 |
The present invention relates to a heat pump system using geothermal sources. The heat pump system comprises a storage tank, which stores a thermal medium heated above a predetermined temperature from the geothermal sources; a pump, which supplies the thermal medium to the storage tank from the thermal sources; an evaporator, which is arranged inside the storage tank and is heat-exchanged between refrigerant flowing inside the storage tank and the thermal medium; a first tube; and a second tube. The first tube is connected to the evaporator and includes a compressor, a condenser, and an expansion valve for a refrigeration cycle. The thermal medium, which is heat-exchanged in the storage tank, is returned to the geothermal sources and is re-heated. The evaporator is submerged into the storage tank. The refrigerant supplied from the expansion valve flows into the inside, so heat is transferred from the thermal medium. The second tube is arranged inside the first tube. The thermal medium stored in the storage tank flows and transmits heat to the refrigerant of the first tube. |
