損する等の不利があった。(Problem to be solved by the invention) The air conditioning inside the dome at an artificial ski resort is divided into two types: air conditioning in the dome environment when many people are entering and using the slope, and air conditioning in the dome environment when many people are entering and using the slope, and when there is no one other than maintenance personnel and there is snow on the slope. However, in the case of the former A in the case of the air conditioning means in the dome using the conventional air conditioning facility, the air pipe C from the air conditioning facility a is connected to the dome. After passing through the outside, it is introduced into the dome and connected to the blowout duct b, which increases the length of the piping and increases costs.This also necessitates insulation management, which may cause concerns about reliability due to deficiencies. In the case of the latter B, the air pipe C stands upright in the center of the ski slope, which has disadvantages such as spoiling the beauty of the inside of the dome during business hours.

In order to achieve a temperature of around 8°C, the telescopic air pipes were reduced in size, the ceiling air duct was separated from the air conditioning equipment, and the air was blown into the dome through the air outlet opened near the top of the ski slope. When maintaining the inside of the dome when the venue is closed, the temperature inside the dome is maintained at around -13°C by extending the telescopic air pipe and communicating it with the intermediate connection port between the air outlet and the ceiling air duct. Cool air is blown into the dome from each nozzle of the duct to improve the quality of the snow on the slopes and to make snow.

For environmental air conditioning inside the dome when the ski resort is open, the communication between the air outlet and the connection port by the air pipe is separated, and cool air is blown directly onto the slope surface from the outlet that opens close to the slope. This improves the quality of the snow on the ski slopes during holidays, etc., and in the case of snowmaking, the air outlet and the connection port are connected by a retractable air pipe, and the air duct blows cold air down from the ceiling into the dome. , the air conditioning of each target area can be performed efficiently, and switching can be done easily and accurately by extending and shortening the telescopic air pipe, and the air pipe is telescopic. Therefore, during business hours, the air pipes are shortened to air condition the inside of the dome, without damaging the beauty of the inside of the dome.Also, during snowmaking, the air pipes are extended and connected to the blow-off duct, so the air outlet opening is not blocked. Therefore, it has effects such as being able to prevent snow that has been made from entering the air outlet.
