Multi-air conditioner for heating and co0ling

A multi-air conditioner for heating and cooling, comprising:

• at least one indoor unit for both cooling and heating comprising an indoor heat exchanger;
• an outdoor unit for both cooling and heating comprising a compressor, a plurality of outdoor heat exchangers, and a four-way valve disposed on a discharge side of the compressor to switch a flow of refrigerant;
• and
• a distributor disposed between the outdoor unit and the at least one indoor unit, that distributes the refrigerant, wherein the plurality of outdoor heat exchangers includes first, second, and third heat exchanges that are selectively coupled or decoupled, wherein the first heat exchanger has a longer flow path than the second heat exchanger, and wherein the third heat exchanger has a shorter flow path than the second heat exchanger.

• a first heat exchanger, a first end of which is connected to the switching unit, and a second end of which is connected to the distributor;
• a second heat exchanger disposed under the first heat exchanger, a first end of which is configured to be coupled to or decoupled from the second end of the first heat exchanger, and a second end of which is connected to the distributor;
• and
• a third heat exchanger disposed under the second heat exchanger, a first end of which is connected to the discharge side of the compressor, and a second end of which is connected to the indoor unit, wherein the first heat exchanger has a longer flow path than the second heat exchanger, and wherein the third heat exchanger has a shorter flow path than the second heat exchanger.
