Fan Coil Unit System Design

Using advanced technology these systems reliably and efficiently deliver the comfort your building occupants need.

Fan coil unit system design.

The extensive selection of available standard and optional features provides the versatility you need to fit any heating ventilation and air conditioning system design. We design unitrane fan coil units as an integral part of the company s system solutions with standard iaq related features that fully comply with ashrae 62. In many ways a fan coil system is similar to the induction system with changeover nonchangeover and four pipe systems being used. As part of an hvac system found in residential commercial and industrial buildings a fan coil unit is often connected to ductwork and a thermostat to regulate the temperature of one or more spaces.

The filters can just be pulled off to be cleaned or they can be replaced. The trane portfolio of fan coil unit ventilator and blower coil solutions are designed to make installations faster and easier and to maximize hvac system performance. Fan coil units are a fairly simple design. In the latter case the ceiling void can be used for the return air.

5b shows a trap for a blow through ahu with the fan off. Figures 5a 5b and 5c. 5a is a general example of a blow through ahu. They may be controlled by local thermostats or by a building management system bms.

Due to their simplicity fan coil units are more economical to install than ducted air handling units. A fan coil unit fcu also known as a vertical fan coil unit vfc is a device consisting of a heat exchanger coil and a fan. The basic components of a fan coil unit are a heating cooling coil fan section and a filter. The terminal units are usually mounted either under the window or in a ceiling void from which a number of supply outlets can be served.

When the fan starts it would create a positive pressure blow through fan and pushes the water away from the pan resulting into proper draining of the system. The refrigerant is pumped through copper pipes to a fan coil unit where it is forced through an expansion valve and a coil where it changes state from a liquid to a gas and absorbs heat from its surroundings. Properties of coils and coil design fan coil units can be used to introduce outdoor air into a space circulate and filter air within a space and provide heating and or cooling within a space. Unitrane fan coil and force flo vertical high rise fan coil still not sure which system is right for you.

Air is blown over the cooling coil through which the refrigerant passes and heat is transferred to the coils and then to the refrigerant. Fan coil units can be wall mounted freestanding or ceiling mounted and may be concealed in ceiling voids. York fan and blower coil units fcus provide maximum performance unparalleled design flexibility and superior serviceability.
