Outdoor air cooling type computer room air conditioner

摘要

PPROBLEM TO BE SOLVED: To provide an air conditioner for a computer room for saving energy in a computer room arranged with a server by effectively utilizing outside air cooling. PSOLUTION: The air conditioner for a computer room is sequentially arranged with a filter, a cooling coil, and a blower fan from upstream, and a humidifier on the upstream or downstream of the cooling coil. The outside air is taken from outdoors and air-conditioned by the cooling coil or the humidifier. When the atmosphere of the outside air is suitable for the computer room, the air is introduced as it is to the computer room and exhausted to the outside. When temperature of the outside air is lower than a predetermined value while enthalpy of the outside air is larger than a predetermined value, and when the temperature of the outside air is higher than the predetermined value while the enthalpy of the outside air is larger than the predetermined value, the air conditioner for the computer room introduces the outside air.
