Fan coil unit design guide

Air Flow Problems. Fan coil units have squirrel cage fans and have limited ability to deal with added air resistance. Sometimes the design of air flow versus resistance is much lower than the actual resistance found on many installations. There are also systems that have dirty plenums, filters, and coils that increase the resistance. Fan coil units can be wall-mounted, freestanding or ceiling-mounted and may be concealed in ceiling voids. 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. Fan coil design is widely used in today's refrigeration (heating) systems. It has the characteristics of small size, easy installation, and high design flexibility. However, how to choose the best solution according to the actual needs of customers and the design drawings should fully consider the following points: 1. Check of cooling capacity The unit design will accommodate up to 1-1/8 inch ex pansion and contraction (2-1/4 in ch total movement) of the riser assemblies. If the total calcul ated riser expansion exceeds 2- 1/4 inches (minimum-to-maximum), the installing contractor must provide and install additional expansion compensation devices in each riser. UNT-PRC015-EN 13 The Engineering Guidelines for Fan Coils discusses the types of fan coils, heat transfer, hydronic systems, room load calculations, psychrometrics, properties of coils and coil design, vertical stack risers, controls and valve packages and thermostats.

Wall, ceiling, and vertical stacking models are available. Some designs are concealed in custom enclosures, semi-recessed into the wall, or installed as floor consoles with various cabinets. the fan type is typically a double inlet centrifugal (forward-curved) or tangential (cross-flow) fan with an efficiency somewhat lower than the larger, heavier, backward-curved and aerofoil-bladed fans that would commonly be used in the supply of a central ahu - forward-curved fans are better suited to low-pressure applications.3 however, unlike … Fan coil unit installations have become one of the most popular means of providing air conditioning in new build and refurbished commercial premises. Their benefits include: • Significantly smaller ventilation plant and distribution ductwork than an all-air system. • High cooling capacity. • Comparatively low capital equip-ment cost.
