<p>PURPOSE: An air conditioning device is provided to selectively use an air-cooled outdoor unit or a geothermal outdoor unit depending on a load, outdoor temperature, or temperature distribution of geothermal heat. CONSTITUTION: An air conditioning device comprises an air handling unit(10), an outdoor unit(40), a geothermal outdoor unit(20), a geothermal heat exchanger(30), a liquid pipe(85), and a gaseous pipe(81). The air handling unit comprises a first heat exchanger(13) and a blower. The outdoor unit is connected to the first heat exchanger and has a second heat exchanger(23) for heat-exchanging outdoor air with a refrigerant. The geothermal outdoor unit is connected to the first heat exchanger and has a third heat exchanger(43). The liquid pipe and the gaseous pipe are connected to the first heat exchanger.</p> |
