<Configuration of air conditioner>
The air conditioner 1 is a multi-type air conditioner for buildings, and has a configuration in which a plurality of indoor units 3 are connected in parallel to one or a plurality of outdoor units 2. The refrigerant circuit 11 of the air conditioner 1 mainly includes a compressor 10, a four-way switching valve 12, an outdoor heat exchanger 13, an outdoor expansion valve 14, an indoor expansion valve 15, and an indoor heat exchanger 16 connected in order. Yes, it is a vapor compression refrigeration cycle.

  The compressor 10, the four-way switching valve 12, the outdoor heat exchanger 13 and the outdoor expansion valve 14 are included in the outdoor unit 2, and the indoor expansion valve 15 and the indoor heat exchanger 16 are included in the indoor unit 3. The four-way switching valve 12 and the indoor heat exchanger 16 are connected by a gas side refrigerant communication pipe 17a, and the outdoor expansion valve 14 and the indoor expansion valve 15 are connected by a liquid side refrigerant communication pipe 17b. . The refrigerant communication pipes 17 a and 17 b are arranged between the outdoor unit 2 and the indoor unit 3. The outdoor unit 2 is also provided with an accumulator and other accessory devices, but the illustration is omitted here.

  The large outdoor unit 2 used in the building air conditioner 1 is provided with a gas-side shut-off valve 18 and a liquid-side shut-off valve 19 at the end of the refrigerant circuit therein. The gas side closing valve 18 is arranged on the four-way switching valve 12 side, and the liquid side closing valve 19 is arranged on the outdoor expansion valve 14 side. A gas side refrigerant communication pipe 17 a is connected to the gas side shutoff valve 18, and a liquid side refrigerant communication pipe 17 b is connected to the liquid side shutoff valve 19. These closing valves 18 and 19 are closed when the outdoor unit 2 and the indoor unit 3 are installed.

FIG. 12 is a diagram illustrating a state of the refrigerant in the compressor 10 when the outdoor unit 2 is transported.

  For example, the case where the outdoor unit 2 is transported by four transporters will be described. When the outdoor unit 2 is transported, in the case of the transporter B shown in FIG. 10 (a transporter in a standing position on the right side with respect to the back surface portion 101 of the outdoor unit 2), as shown in FIG. Is inserted into the right handle 20R, the handle 20R is grasped with the left hand, and the right palm is attached to the column 81 positioned further to the left of the handle 20R.

  On the other hand, in the case of the carrier A shown in FIG. 10 (the carrier in the standing position on the left side with respect to the rear surface portion 101 of the outdoor unit 2), on the contrary to the carrier B, the right hand of the carrier A is placed on the left handle 20L. And the handle 20L is gripped with the right hand, and the left palm is attached to the column 84 positioned further to the left of the handle 20L.

  Then, the carrier D shown in FIG. 10 (the carrier in the standing position on the right side with respect to the front portion 102 of the outdoor unit 2) places the right hand of the carrier D on the side wall of the right side portion 106, as shown in FIG. Insert from the gap below 106 a, grasp the lower part of the side wall 106 a, and attach the palm of the left hand to the column 83.

  On the other hand, the carrier C shown in FIG. 10 (the carrier in the standing position on the left side with respect to the front portion 102 of the outdoor unit 2) inserts the left hand of the carrier C into the gap below the side wall 105a of the left side 105. Then, grasp the lower part of the side wall 105 a and attach the palm of the right hand to the support 82.

  As described above, the carriers A and B grip the handles 20R and 20L and the columns 81 and 84 with the back surface 101 facing downward, and the carriers C and D transfer the side wall 102a and the column 82 of the front unit 102. , 83 and the carriers C and D move the columns 82 and 83 on both sides of the front part 102, the left side wall 105a and the right side wall 106a, which are positioned above the rear part 101.
