The fan coil unit consists of a cooling or heating coil. Such units are typically a part of heating and air conditioning systems. The fan coil unit may be used in all sorts of capacities.
The fan cooling unit is not part of the air conditioning or heating unit itself and there is no required connection to any ductwork within a structure. Instead, the fan coil unit generally is a stand alone device installed to adjust temperatures in its location. Often, the device is controlled by a thermostat that tells it when to come on and shut off.
There are some units that still operate by a manual switch. This requires the user to shut it on and off. These types of devices are used in the heating and cooling of all types of buildings, including residential, commercial, and industrial facilities.
Fan coil units may be more cost efficient than their air handling unit counterparts for a number of reasons. First, they are more financially feasible given that they need no ductwork installed to make them operational. They can also be installed in many different ways, such as horizontally using a ceiling mount or vertically using a floor mount.
