Fan Coil Units: In-Room Horizontal
Our previous article highlights the variables to consider when choosing a Horizontal Fan Coil design for a project. The highest volume unit type in the industry is the in-room horizontal fan coil unit. The units are ideal for hotel rooms, condominiums, and small offices. They are typically installed above a ceiling and supply directly to the room they serve. The air returns through a grille in the ceiling, either directly into the unit or through the plenum. This article will discuss how the units work, the options available for each unit, and the design considerations when choosing an in-room horizontal fan coil unit.

Square Ceiling Diffusers: What are the Differences?
When selecting square ceiling diffusers, many of the options available can seem quite similar outside of appearances. With so many different standard 24 x 24 ceiling diffusers on the market and in Nailor catalogs, engineers could be hard-pressed to find what differentiates each product. The differences, however, can vary from obvious ones like performance and noise to lesser-known variables like throw patterns and specialized applications, all of which can affect the overall comfort in the space.
Nailor RNS
The Nailor RNS includes three configurations ranging from 2 to 4 cones. For example, the standard 4-cone stamped square diffuser (RNS) is quite similar to the 3-cone (RNS3) and 2-cone (RNS2) diffusers that came after. If selecting for high inlet pressures, the 2-cone RNS2 is a… Read more
5 Variables to Consider when Choosing a Horizontal Fan Coil
Chilled water fan coils are small air handling units that range from 200-4,000 CFM. Several commercially available product types serve multiple applications. In some instances, choosing which product is best for your application is difficult. There are two main configurations: vertical & horizontal. Horizontal units are typically located above a ceiling while vertical units are installed in a closet or exposed in the room. The selection between vertical and horizontal are made during the building design phase, and there will be little debate over where the project needs a horizontal or vertical. Choosing the right horizontal product for an application requires an understanding of the types available.

Ventilation Strategies: Chilled Water Fan Powered Terminal Units
The most advanced system for delivering, controlling, and optimizing ventilation air utilizes Chilled Water Fan Powered Terminal Units. With this system, the DOAS unit handles the conditioning of the ventilation air and the latent load within the building. The system eliminates the need for the recirculating air system to handle latent loads and distributes the sensible cooling into the space.
Achieving this system requires series fan-powered terminal units that are equipped with a sensible cooling coil, eliminating the need for the building air handling unit.
Chilled Water Fan Powered Terminal UnitsChilled water fan-powered terminal units contain the following parts:
Flow Sensor
Damper
Fan
Sensible Cooling Coil
Optional – Heating Coil
The dedicated outside air unit supply is ducted to… Read more
