As the refrigerant, an easily volatile liquid such as Freon is used, but cold or hot water may be used. Air conditioning is to adjust the room temperature and the like in the building to a predetermined temperature and humidity,
A refrigerant supplied from an air-conditioning heat source unit, which is an outdoor unit such as an air conditioner, is supplied to an air-conditioning indoor unit installed in a living space or the like via an outgoing pipe 1 and exchanges heat with indoor air. It is to return to.

The air-conditioning heat source unit may be an air conditioner equipped with an electric or gas type heat pump or an electric or gas type boiler.

The air-conditioning system is composed of the air-conditioning heat source unit, piping, and air-conditioning indoor unit.

The outgoing pipe 1 and the return pipe 2 are respectively composed of pipe bodies 11 and 21 and heat insulating materials 12 and 22 that cover the outer circumferences of the pipe bodies 11 and 21. Then, the thickness of the heat insulating material 22 of the return pipe 2 is made smaller than the thickness of the heat insulating material 12 of the outgoing pipe 1, whereby the outer pipe diameter of the outgoing pipe 1 is larger than the outer pipe diameter of the return pipe 2.

The air-conditioning piping shown in FIG. 1A is used through a dedicated piping space or the like in the wall of the building or in the building. Since the pipes are different from each other, it is possible to distinguish the forward and return pipes by gripping the pipes 1 and 2 without relying on the visual sense, even in a dark place such as under the floor, at the time of pipe construction, and there is no connection error.

Since the thickness of the heat insulating material 22 of the return pipe 2 is smaller than the thickness of the heat insulating material 12 of the going pipe 1,
The heat insulating material of the return pipe 2 can be saved correspondingly, and the cost can be reduced.

For example, if the temperature of the refrigerant at the time of cooling is set to 7 ° C., the thickness of the heat insulating material is determined from the relationship between the refrigerant temperature of 7 ° C. and the outside air temperature in this air conditioning piping in order to prevent condensation.
At this time, the temperature of the refrigerant passing through the return pipe 2 is at least 7 ° C.
