<p>PURPOSE: A geothermal heat pump is provided to accurately measure the actual temperature of fluid in cold/hot water and refrigerant circulation pipes through a temperature measuring unit installed inside the pipes, thereby enabling accurate management and control of the pump system. CONSTITUTION: A geothermal heat pump comprises a terrestrial heat exchange unit(10), a heat pump unit(20), a pipeline(30), a temperature measuring unit(40), and a controller(50). The terrestrial heat exchange unit is laid under the ground. The heat pump unit allows cooling and heating through heat exchange with the terrestrial heat exchange unit. The pipeline connects the terrestrial heat exchange unit and the heat pump unit and circulates geothermal water, refrigerant, and cold and hot water. The temperature measuring unit comprises a casing and a temperature sensor which is inserted and fixed in casing The controller comprises a temperature input part in which each spot temperature measured by the temperature measuring unit is inputted, an alarm part which makes an alarm according to the difference between supply and recovery temperatures of fluid, and a switching element which opens and closes the heat pump unit according to the alarm of the alarm part.</p> |
