At the installation site, the refrigerant pipe extending from the indoor unit is connected to the packed valve, and at the same time, the refrigerant can be conducted to the indoor unit and the outdoor unit. Conventionally, as shown in FIGS. 5 and 6, a connecting pipe structure for connecting a refrigerant pipe to a packed valve has been used.

The refrigerant pipes Pa and Pb extending from the indoor unit are bent from the vertical direction to the horizontal direction and connected to the connection port body.

The refrigerant pipes Pa and Pb extending from the indoor unit are once bent obliquely downward from the vertical direction, and only one refrigerant pipe Pa is further bent vertically to be connected to the one connection port body 4a. It

By the way, in the case of so-called horizontal extraction in which the connection ports 4a and 4b of the packed valves 3a and 3b are oriented horizontally, as shown in FIG. 5, the refrigerant pipes Pa and Pb are placed horizontally. The length of the bent portion must be ensured to the minimum necessary. On the other hand, if the required length is ensured, the vertical portion projects rearward from the back side of the outdoor unit body 1.

Therefore, the back surface of the outdoor unit main body 1 must be arranged with a gap from the wall surface of the installation site, which hinders the reduction of the installation space. If the protruding positions of the packed valves 3a and 3b are changed to the front surface of the outdoor unit main body 1 and the refrigerant pipes Pa and Pb are connected thereto, the rear surface of the main body can be brought into close contact with the wall surface of the installation site.

However, this time, not only the piping of the respective refrigerant pipes Pa and Pb becomes very troublesome, but also the aesthetic appearance is impaired, and the refrigerant pipes obstruct the maintenance work performed from the front side.

However, in the case of the same figure, since the end portions of the refrigerant pipes Pa and Pb extending in the vertical direction are bent in a horizontal direction at a substantially right angle and then cut, the length is long after cutting once. Adjustment is difficult.

When the refrigerant pipes Pa and Pb are cut to a length shorter than the regular length, the flare ends are left as they are and the connection ports 4a,

Therefore, the outdoor unit main body 1 is always subjected to tension in the direction of floating from the installation surface, which may cause breakage deformation of the refrigerant pipes Pa and Pb. In particular, stress is applied to the flared end portion. Concentrated and cause gas leak.

Further, when the refrigerant pipes Pa and Pb are cut longer than the regular length, the flare ends are overlapped with the connection ports 4a and 4b, so that the vertical portion of the refrigerant pipe is cut short. Will be bent diagonally in the opposite direction and will be forced to connect.

The flare ends of the connection ports and the connection ports 4a and 4b are misaligned with each other, which makes it difficult to perform accurate alignment and secure nut tightening cannot be performed. It is necessary to cut the end of the refrigerant tube and perform flare processing again, and in some cases, the refrigerant tube must be reconnected from the beginning.

In the structure of FIG. 6, it is difficult to set the angle at which the refrigerant pipes Pa and Pb are bent at an angle and the required length thereof. That is, the middle part of each refrigerant pipe must be bent in a three-dimensional and complicated manner, and it is difficult to accurately determine the cutting position.

When the cut end does not coincide with the position of the connection ports 4a and 4b, the position can be adjusted by changing the bending angle in the middle, but on the other hand, for removing the pipe provided in the packed valve cover 51. In some cases, the refrigerant pipes Pa and Pb may be inserted in the biased positions of the notch 52 to form a large gap, or the refrigerant pipe may come into contact with the notch so that the refrigerant pipe cannot be taken out.

Since the cutout 52 is provided on the upper surface of the cover 51, if a large gap is formed, dust and rainwater can easily enter. Further, since the refrigerant pipe is inserted, it takes time and effort to further increase the notch area.

The diameters of the connection ports 4a and 4b are different from each other. The diameter of the connection port 4a on the lower side in the figure is large and the diameter of the connection port 4b on the upper side is small. The large-diameter refrigerant pipe Pa connected to the large-diameter connection port body 4a as described below is a gas refrigerant introduced into a heat exchanger (not shown) arranged in the outdoor unit body 1 during the cooling operation. The small-diameter refrigerant pipe Pb connected to the small-diameter connection port body 4b guides the liquid refrigerant drawn from the heat exchanger during the same operation.

Therefore, the refrigerant pipe P extending from the indoor unit
a and Pb are hung from the upper part of the outdoor unit main body 1 and bent in the inclined state near the packed valves 3a and 3b.
As described above, the refrigerant pipe has a large diameter Pa and a small diameter Pb. In particular, the large diameter refrigerant pipe Pa is used.
The end portion is bent along the longitudinal line 6a of the marking portion 5.

That is, the worker is to check the longitudinal line 6a of the marking portion 5.
Since it suffices to bend it so that the end of the refrigerant pipe Pa overlaps with it, the work becomes easy. At this time, the small diameter refrigerant pipe Pb is bent together with the large diameter refrigerant pipe Pa. (In general, the large-diameter refrigerant pipe Pa and the small-diameter refrigerant pipe Pb are often integrated.) Then, the entire length of the length standard gauge 10 described on the name plate 7 is directly transferred to the refrigerant pipe Pa. In addition, as described in the piping work description 8 of the nameplate 7, some kind of mark may be made from here to the standard gauge length AAmm with reference to the short line 6b of the marking part 5.
This mark becomes a cutting line, and the operator can easily know the cutting position.

In this way, by performing the work according to the description 8 of the piping work, the flare end portion is connected to the connection port body 4.
Accurately hits a and there is no displacement. In the refrigerant pipe Pb on the small diameter side, after flaring the cut end,
Bend it further and make the flare end the upper packed valve 3b.
It is applied to the connection port body 4b. Since it has a small diameter, it can be easily bent, and by performing the work according to the piping work description 8, the flare end accurately hits the connection port body 4b,
There is no misalignment.
