FAU is a constricted form of Forced Air Unit. A forced-air unit is a heat transfer medium that makes use of a central furnace to pump heat through ducts into registers often located in floors and ceilings. The heat generated by this system is taking place at a central location and transferred throughout the entire building.

Sep 9, 2023 · A fan coil unit (FCU) is a terminal device of an air conditioning system. It operates by continuously recirculating the air in a room, passing it over a coil containing cold (or hot) water, thereby cooling (or heating) the air to maintain a constant room temperature.

Jan 29, 2013 · Fan with heat and cooling coil = FAU, Furnace, or I prefer "fan coil with gas (or electric) heat" fan with or without heat or cooling but 100% outside air = MAU. Unit that doesn't look like a furnace (commercial) with fan (with or without heat and cooling coils) = AHU.

While fan coils operate, they can help improve your indoor air quality by preventing buildup and circulation of mold, select viruses, bacteria and other airborne pollutants. Variable-speed and two-speed fan coils can improve airflow, resulting in enhanced control of your indoor air quality.

Mar 26, 2025 · FCU (full name: Fan Coil Unit) The fan coil unit is the end device of the air conditioning system. Its working principle is the continuous recirculation in the unit. The air in the room is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant.

Feb 5, 2023 · The pre-cooling air conditioning box is generally used in conjunction with the fan coil unit FCU. Its function is to pre-treat the outdoor fresh air and then send it to FCU.

A FAU is a Forced Air Unit, which is another name for an air handler, indoor unit, or AHU for short. Whatever you call it, it consists of a blower, air conditioning coils, and sometimes electric heat strips or a hydronic coil, all wrapped up in a furnace-shaped package.

Jan 9, 2025 · In the HVAC industry, FCU (Fan Coil Unit), AHU, MAU, FFU and Heat Pump are the core components. Each device has different functions, principles and applicable scenarios. Understanding their differences and connections can not only help optimize system design, but also improve energy efficiency.

Apr 20, 2022 · In the HVAC industry and air conditioning system, FCU, AHU, PAU, RCU, MAU, FU, HRV, FAU, OAC and EAF are often heard - a series of strange terms. So, what do these letters mean by the concepts they represent? What's the difference between them? 1. FCU (full name: Fan Coil Unit fan coil)

Jun 3, 2024 · The main difference between an air handling unit and a fan coil unit is that an air handling unit is an assembly consisting of at least one fan, while a fan coil unit provides air circulation and heating and/or cooling.
