Server room managing air conditioning system

A server room managing air conditioning system, which takes in returned air of a server room as an air conditioning control subject, and supplies, to the server room, supplied air adjusted to a supplied air temperature target value and a supplied air humidity target value, the air conditioning system comprising:

• a first coil that adjusts the returned air of the server room to a predetermined temperature value lower than the supplied air temperature target value and dehumidifies the returned air;
• a second coil that is installed in a same area as an area of the first coil, and adjusts the returned air of the server room to a predetermined temperature value higher than the supplied air temperature target value so that the supplied air temperature target value and the supplied air humidity target value can be achieved when the returned air is mixed with air adjusted by the first coil;
• and
• an air supply fan that mixes the returned air adjusted by the first coil and the returned air adjusted by the second coil with each other and supplies the mixed returned air as the supplied air to the server room.
