USING A GAS ENGINE HEAT PUMP GEOTHERMAL HEATING AND COOLING SYSTEMS

摘要

PURPOSE: A cooling and heating system with a gas engine heat pump using geothermal heat is provided to improve cooling performance of a cooling and heating device in the gas engine heat pump by utilizing the geothermal heat as sub heat sources. CONSTITUTION: A cooling and heating system with a gas engine heat pump using geothermal heat comprises a cooling and heating device(100), an indoor unit(110), an outdoor unit(120), and three way valves(132,133). The indoor unit comprises an indoor heat exchanger(111) and a blower. The indoor heat exchanger discharges cold air or warm air. The blower supplies the discharged heat from the heat exchanger to a room. The out door unit comprises an outdoor heat exchanger(121) and the blower. The outdoor heat exchanger comprises a compressor connected to the indoor unit. The blower emits the heat to the outside. The three way valves are connected toward a thermal heat exchanger(200) in a refrigerant circuit.
