Economizers lower energy cost by using less conditioned air

Conditioned Air

When outdoor conditions are favorable, economizers open outside air dampers and louvers to allow more outdoor air to be brought in to cool commercial buildings. The Model RHT-O Outdoor Humidity and Temperature transmitter monitors the humidity and temperature outside while the RHU-D measures the humidity in the return and supply air duct. A economizer controller will compare the temperature and humidity supplied by the transmitters to determine the position of the supply air and return air dampers.
