Definition
The Outside Air Unit means an air control for taken-in outside air.
Intake of the outside air often influences on the system so that the normal control of the air conditioner
becomes difficult or gives a large load upon air control and cooling performance.
Therefore it is frequently adopted to handle the outside air to a certain condition before the outside air will
enter in the main air conditioner.
This handling device is called a Outside Air Unit.
NOTE:
The Outside Air Unit is an air conditioner provided to handle the outside air load and is not to control the room
temperature.
For correspondence to the load of the indoor air control, set an air conditioner separately.
