However, a dedicated air conditioning system is required, but a large work facility where a melting furnace or the like is installed is very expensive and it is not realistic to provide many air conditioning systems.

In the summer, even if the outside air is forwarded into the hot facility, the temperature inside the room cannot be lowered. Further, in Patent Document 3, the outside air is purified and cooled using the heat of vaporization and taken into the room.
