HVAC Damper Actuator for Economizer Free CoolingHVAC Damper Actuator for Economizer Free Cooling

This damper actuator controls a free cooling damper for an economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. In the Fall and the Spring when the outside air temperatures are mild it is unnecessary to run the air conditioning system to cool the building if the system is set up for free cooling. The air conditioning system has duct work running to the outside. When the control system program calls for free cooling the outside air damper opens and the system draws in cool air from the outside. Another damper directs the return air, which originates inside the spaces of the building, to the outside. This brings cool conditioned air into the building while exhausting the warmer air to the outside. Another action that the control program initiates is the lockout of the air conditioner or mechanical cooling.
