WebMay 1, 2007 · Airside economizers have been an integral part of building HVAC systems for more than five decades, yet in many ways they're still misunderstood, misapplied, and — in many cases — operating poorly. We install them because we believe they provide a level of energy reduction and perhaps improved indoor air quality. WebMay 31, 2024 · An economizer control is a mechanical device that uses cool outside air to cool inside a building, thus reducing the need for electrical cooling. The control is installed as a part of the ventilation/cooling system. …. Energy used by the compressor accounts for most of the total electricity consumed.
WebOur waterside economizer (WiSE) is an energy-saving system that uses a cooling tower, condenser, water piping, control valves, and water coils to provide cooling without compressor operation. This innovation, which can be integrated into our Dedicated Outdoor Air Systems, is often referred to as “free cooling.” WebAir economizers draw in outdoor air in order to meet the thermostat setpoint without using the air conditioner. This process is known as “free cooling.” The economizer controllers determine when the outdoor environment is favorable and commence the free cooling process. Economizers typically operate at night when outdoor air is cooler than ...
