74. OR ACCESSORIES Economizer dry bulb or enthalpy Economizers save money They bring in fresh outside air for ventilation and provide cool outside air to cool your building This is the preferred method of low ambient cooling When coupled to sensors Economizers can provide even more savings by coupling the ventilation air to only that amount required Economizers are available installed and tested by the factory with either enthalpy or dry bulb temperature inputs There are also models for electromechanical as well as direct digital controllers Additional sensors are available as accessories to optimize the economizers CO Sensor Improves productivity and saves money by working with the economizer to intake only the correct amount of outside air for ventilation As occupants fill your building the CO sensor detects their presence through increasing levels and opens the economizer appropriately When the occupants leave the levels decrease and the sensor appropriately closes the economizer This intelligent control of the ventilation air called Demand Control Ventilation DCV reduces the overall load on the rooftop saving money Smoke Detectors Trust the experts Smoke detectors make your application safer and your job easier Carrier s smoke detectors immediately shut down the rooftop unit when smoke is detected They are available installed by the factory for supply air return air or both
