Airside energy recovery is the process of using the building's exhaust air to pre-condition the ventilation air for the building. The exhaust air passes through an energy recovery device such as a rotating heat wheel, a fixed plate heat exchanger, or a run-around coil. The energy from the exhaust air stream is transferred to or from the outside airside. In the summer, the temperature of the warmer, humid outside air is reduced before entering the air conditioning system, which reduces air conditioning system tonnage. In the winter, the cold outside air is warmed before heaters heat the air to maintain the space temperature.
A water-cooled system relies on chillers to cool the water, which is then distributed to air-handling units to condition the space. The heat from the air-handler coils is returned to the chiller where the head is returned to the air via fans or a cooling tower. Waterside energy recovery systems capture some of the heat from the building before it is rejected. This recovered energy is often used to temper the building's heating hot water.
Digital outputs are typically relay contacts used to start and stop equipment, and analog outputs are typically voltage or current signals to control the movement of the medium (air/water/steam) control devices such as valves, dampers, and motors.
