Air conditioning apparatus

An air conditioning apparatus comprising:

• an outdoor unit which comprises a compressor and an outdoor heat exchanger and through which a refrigerant is circulated;
• an indoor unit through which water is circulated;
• and
• a heat exchange device comprising a first heat exchanger and a second heat exchanger, in which the refrigerant and the water are heat-exchanged with each other, wherein the heat exchange device comprises:
• a first high-pressure guide tube extending from a high-pressure gas tube of the outdoor unit so as to be connected to one side of the first heat exchanger;
• a second high-pressure guide tube extending from the high-pressure gas tube of the outdoor unit so as to be connected to one side of the second heat exchanger;
• a first low-pressure guide tube extending from a low-pressure gas tube of the outdoor unit so as to be combined with the first high-pressure guide tube;
• a second low-pressure guide tube extending from the low-pressure gas tube of the outdoor unit so as to be combined with the second high-pressure guide tube;
• a first liquid guide tube extending from a liquid tube of the outdoor unit so as to be connected to another side of the first heat exchanger;
• a second liquid guide tube extending from the liquid tube of the outdoor unit so as to be connected to another side of the second heat exchanger;
• a bypass tube configured to bypass a high-pressure refrigerant of the high-pressure gas tube to the first liquid guide tube or the second liquid guide tube;
• and
• a bypass valve installed in the bypass tube, wherein the outdoor unit comprises:
• a first valve device configured to guide the refrigerant compressed in the compressor to the outdoor heat exchanger;
• and
• a second valve device configured to the refrigerant compressed in the compressor to the first high-pressure guide tube or the second high-pressure guide tube.
