In the above embodiment, the connection pipe 3
Although a detailed description of 0 and the indoor side connection pipe 30A is omitted, a flexible pipe or a resin pipe may be used as such a connection pipe. By using an HC-based refrigerant such as propane or isobutane as the refrigerant used in the air-conditioning apparatus, the pipe diameter of the connection pipe can be set to 75 to 70% in comparison with a conventional refrigerant such as R22.
The diameter can be set to 80% and 15 to 58% in the liquid side piping. Since the pipe diameter can be reduced in this way, the strength required for the connection pipe can be reduced. Therefore, it becomes possible to use a flexible pipe or a resin pipe, and by using such a pipe as a connection pipe,
Workability during installation can be improved. That is, by using a flexible pipe or a resin pipe, the same handling as the cable can be performed, so that the workability is high. Also, since it can be handled integrally with electric wires and signal lines, the workability is good. In addition, since a long pipe can be used, the number of connection portions can be reduced, and leakage can be prevented. As the resin pipe, a resin reinforced with glass fiber (GF / ABS, GF / PP) can be used.
