A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling.

FCU（全称：Fan Coil Unit 风机盘管） 风机盘管是空调系统的末端装置，其工作原理是机组内不断的再循环所在房间的空气，使空气通 过冷水（热水）盘管后被冷却（加热），以保持房间温度的恒定。

预冷空调箱一般都是与风机盘管FCU配合使用的，功能是对室外新风进行预处理，再送至风机盘管 (FCU)。 循环空调箱也叫室内空气循环机组，主要是吸入和排出室内空气，以确保室内空气循环。 全新风机组，是提供新鲜空气的一种空气调节设备。 功能上按使用环境的要求可以达到恒温恒湿或者单纯提供新鲜空气。 工作原理是在室外抽取新鲜的空气，经过除尘、除湿 (或加湿)、降温 (或升温)等处理后通过风机送到室内，在进入室内空间时替换室内原有的空气。 当然以上所提到的 …

2019年12月20日 · 风机盘管：Fan Control Unit 风机盘管是空调系统的末端装置，其工作原理是机组内不断的再循环所在房间的空气，使空气通 过冷水（热水）盘管后被冷却（加热），以保持房间温度的恒定。 主要依靠风机的强制作用，使空气通过加热器表面时被加热，因而强化了散热器与空气间的对流换热器，能够迅速加热房间的空气。 变风量空调系统（VAV）控制原理：变风量控制器和房间温控器一起构成室内串级控制，采用室内温度为主控制量，空气流量为辅助控制量。 …

2024年8月9日 · FCU (风机盘管) 是空调系统的末端设备，通过循环室内空气，经过盘管加热或冷却，维持室内温度恒定。 2. AHU (空气处理机组) 是一种多功能设备，负责空气的过滤、热湿处理，提供恒温恒湿和空气洁净环境，有吊顶式、立式等多种形式。 3. HRV (全热交换器) 是一种节能系统，回收并利用空气中的热量，提高空调效率，保持室内舒适度。 4. FAU (新风机组) 专门用于引入新鲜空气，经过处理后替换室内空气，与AHU的区别在于AHU包含回风工况。 5. PAU ( …

2023年8月16日 · What is a fan coil unit, what does it do & how does it work?… A fan coil unit is a relatively small piece of equipment that consists of a fan, a coil, and other components, that are used to cool or heat the air recirculating within a room. Some will also add fresh air to the space.

2022年5月8日 · In this article you’ll learn what a Fan Coil Unit (FCU) is, and where they’re mostly used in the commercial HVAC industry. We’ll cover the different types of fan coils, including 2-pipe, 4-pipe, horizontal and vertical.

2023年2月5日 · FCU: Fan Coil Unit. The fan coil unit is the terminal device of the air conditioning system. It is for continuously recirculating the air in the room where the unit is located, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant.

2023年2月10日 · A fan coil unit (FCU) is a stand-alone heating and cooling unit that does not require ductwork. Fan coil units are incredibly versatile. They can control the temperatures of individual rooms, connect to ductwork to serve multiple rooms, and be paired with air conditioners, heat pumps, and furnaces for supplemental heating and cooling.

2019年7月3日 · FCU stands for fan coil unit but often engineers will just call them a fan coil, to save time. Fan coil units are very common in all types of buildings, from offices, bars, canteens, even some homes and apartments will have a fan coil unit in them.
