Abstract
An air conditioning apparatus may include an outdoor unit through which a first fluid, such as refrigerant circulates, an indoor unit through which a second fluid, such as water circulates, a heat exchange device which is configured to connect the outdoor unit to the indoor unit and in which the first fluid and the second fluid are heat-exchanged with each other, first to third inner tubes configured to connect the outdoor unit to the heat exchange device, and a heat storage unit connected to the first to third inner tubes.
Claims20
An air conditioning apparatus, comprising:
- an outdoor unit through which a refrigerant circulates;
- an indoor unit through which a fluid circulates;
- and
- a heat exchange device which is configured to connect the outdoor unit to the indoor unit and in which the refrigerant and the fluid are heat-exchanged with each other, wherein the heat exchange device comprises:
- first to third inner tubes connected to an outdoor unit connection tube provided in the outdoor unit, and a heat storage unit connected to the first to third inner tubes to store heat transferred through the first inner tube, thereby dissipating the heat through the second inner tube.
An air conditioning apparatus, comprising:
- an outdoor unit through which a first fluid circulates;
- an indoor unit through which a second fluid circulates;
- and
- a heat exchange device which is configured to connect the outdoor unit to the indoor unit and in which the first fluid and the second fluid are heat-exchanged with each other, wherein the heat exchange device comprises:
- a plurality of inner tubes connected to the outdoor unit, and a heat storage unit connected to the plurality of inner tubes to store heat transferred through a first inner tube of the plurality of inner tubes, thereby dissipating the heat through a second inner tube of the plurality of inner tubes;
- a first heat storage branch tube branched from the first inner tube;
- a first heat storage valve provided in the first heat storage branch tube;
- a second heat storage branch tube branched from the second inner tube;
- and
- a second heat storage valve provided in the second heat storage branch tube, wherein when a heating operation is performed, the first heat storage valve is opened and the second heat storage valve is closed;
- wherein when a defrosting operation is performed, the second heat storage valve is opened and the first heat storage valve is closed;
- and wherein when an oil collection operation is performed, the second heat storage valve is opened and the first heat storage valve is closed.
An air conditioning apparatus, comprising:
- an outdoor unit through which a first fluid circulates;
