팬 코일 장치는 무엇입니까?
FanCoilUnit(FCU) is the core end equipment of the central air-conditioning system, which regulates the indoor temperature through hot and cold water circulation, and is widely used in hotels, office buildings and residences. Its high efficiency and energy saving, flexible installation features make it the first choice for modern building HVAC system.
Working principle of Fan coil unit
FCU consists of fan, heat exchanger, motor and other components, the working principle is divided into three steps:
1. Hot and cold media circulation: cold water (7°C) or hot water flows through the heat exchanger and exchanges heat with the air.
2. Air conditioning: the fan drives the indoor air through the heat exchanger to realize cooling or heating.
3. Intelligent control: support thermostat or building automation system (such as BACnet protocol) precise regulation.
The main type of fan coil unit
설치 방법：
1.Exposed FCU: such as wall-mounted, vertical, suitable for the space that has been decorated, convenient maintenance
2.Concealed FCU: hidden in the ceiling, beautiful and space-saving, requires pre-buried piping.
3. Vertical FCU: wall or floor mounted, suitable for places without ceiling.
4.Cassette/wall-mounted: compact size, suitable for small space or localized temperature control.
Air Volume and pressure：
1.Low static pressure type (≤30Pa): suitable for small space (such as residential).
2.High static pressure type (≥50Pa): to meet the large space and long distance air supply (such as shopping malls).
What is the advantage of fan coil unit？
.1Energy saving and high efficiency: energy efficiency ratio (EER) of 3.5 or more, reducing operating costs.
2.Silent design: the noise of high quality motor is as low as 30dB, suitable for hospitals and hotels.
3.Flexible adaptation: compatible with two-control (hot and cold switching) and four-control (synchronized hot and cold) 시스템.
