Fan Coil Air System



The fan coil air system information states that the equipment supplies a constant volume of air at a varied temperature to the area served. The air may be full return air or a combination of return and outside air. If a combination of air, the unit will have a mixing box control.

If operating on return air only, the unit will have a chilled water cooling coil or evaporator coil with self contained direct expansion cooling.

The blower fan can run continuously or be cycled on and off on a demand for heating or cooling.

Heating can be provided by a hot water heating coil or gas fired section.

A wall mounted thermostat controls the blower heating and cooling section on and off to maintain the serviced area at the set point of the thermostat.
