FAQ - Industrial Fan Coils

Question 1

What is a fan coil and how does it work?

Accepted Answer

A Fan Coil Unit (FCU) is an HVAC unit that uses chilled or hot water circulating through a coil, while a fan forces air through it. The air is cooled or heated and distributed throughout the space. It is an efficient system for zoned climate control.

Question 2

What is the difference between a 2-pipe and 4-pipe fan coil?

Accepted Answer

The 2-pipe system uses a single coil for heating or cooling (not simultaneous). The 4-pipe system has two independent coils, allowing simultaneous heating and cooling in different building zones.

Question 3

Can a fan coil be used in an industrial warehouse?

Accepted Answer

Yes, high-capacity industrial fan coils (up to 50 TR) are ideal for warehouses, production areas and distribution centers. They can be installed on the ceiling, floor or connected to ducts for air distribution.

Question 4

What maintenance is required for a fan coil?

Accepted Answer

Basic maintenance includes cleaning or replacing filters (monthly/quarterly), coil cleaning (semi-annual), condensate tray inspection and motor lubrication (annual). Fan coils have simple and low-cost maintenance.

Question 5

What is the ideal chilled water temperature for a fan coil?

Accepted Answer

The standard chilled water temperature is 7°C inlet and 12°C outlet (delta T of 5°C). For hot water, 45°C inlet and 40°C outlet is used. These temperatures can be adjusted according to the application.

Question 6

Is a fan coil more efficient than split air conditioning?

Accepted Answer

For large areas and commercial/industrial buildings, yes. The chilled water system with fan coils is more energy efficient, allows better zoned control, has a longer lifespan and lower long-term maintenance costs.
