The air conditioner circulates a refrigerant in a refrigerant circuit including the outdoor heat exchanger, the indoor heat exchanger, and the refrigerant communication tubes (GP, L P) to perform air conditioning of an air conditioning target space in which the indoor unit is disposed.A refrigerant circuit includes refrigerant tubes (21, 22) made of a metal material, refrigerant communication tubes (GP, L P) made of a metal material different from the refrigerant tubes (21, 22), and connections (21a, 22a) between the refrigerant tubes (21, 22) and the liquid refrigerant communication tubes (GP, L P). The connections are disposed in a non-ventilation space (90).)

1. An air conditioner (100) that includes a heat source-side unit (10) having a heat source-side heat exchanger (13), a usage-side unit (20) having a usage-side heat exchanger (25) and a usage-side fan (28) that supplies air to the usage-side heat exchanger, and a refrigerant communication pipe (GP, L P) that connects the heat source-side unit and the usage-side unit, and that performs air conditioning of an air-conditioning target space in which the usage-side unit is disposed by circulating refrigerant in a Refrigerant Circuit (RC) that includes the heat source-side heat exchanger, the usage-side heat exchanger, and the refrigerant communication pipe,

the refrigerant circuit includes first pipes (21, 22) made of a metal material, second pipes (GP, L P) made of a metal material different from the metal material of the first pipes, and connection portions (21a, 22a) between the first pipes and the second pipes,

the connecting portion is disposed in a non-ventilation space (90, 94).

2. The air conditioner according to claim 1,

the usage-side unit further has a casing (30) that houses the usage-side heat exchanger and the usage-side fan,

the air conditioner further includes a wind shielding member (92, 92a, 96) forming the non-ventilation space inside the casing,

the connecting portion is disposed in the non-ventilation space (90) formed in the housing by the wind shielding member.

3. An air conditioner according to claim 2,

the wind shielding member is disposed downstream of the usage-side fan and upstream of the connection portion in an air blowing direction of the usage-side fan, and the non-ventilation space in which the connection portion is disposed is formed downstream of the wind shielding member.

4. An air conditioner according to claim 2 or 3,

the air conditioner further includes a dew condensation prevention member (98) which is disposed around the connection portion and is different from the wind shielding member.

5. The air conditioner according to claim 1,

the air conditioner further includes a cover member (96) that covers the periphery of the connection portion and forms the non-ventilation space inside.

6. The air conditioner according to claim 1,

the first pipe is a pipe provided in the usage-side unit,

the usage-side unit further has a casing (30) that houses the usage-side heat exchanger and the usage-side fan,

the connecting part is arranged outside the shell.

7. An air conditioner according to any one of claims 1 to 6,

the non-ventilation space is a space in which the air speed is 0.5 m/sec or less when the air conditioner is in operation.

8. An air conditioner according to any one of claims 1 to 6,

the non-ventilated space is a space: the wind speed of the non-air-space when the usage-side fan has a maximum air volume is 1/5 or less of the wind speed of the air-space through which the air blown by the usage-side fan passes when the usage-side fan has the maximum air volume.

9. An air conditioner according to any one of claims 1 to 8,

one of the metal material of the first pipe and the metal material of the second pipe is aluminum or an aluminum alloy, and the other is copper or a copper alloy.
