Method Statement for Fan Coil Unit Installation in HVAC Systems

Basic of Fan Coil Unit (FCU)

What is a Fan Coil Unit?

A Fan Coil Unit is a simple air handling device found in many HVAC systems.

It's designed to heat or cool a specific space by circulating air over a coil filled with hot or chilled water.

Basic Components of an FCU:

Fan (Blower): Circulates air into the room,
Coil: Transfers heat or coolness to the air (using hot/cold water)❄️,
Filter: Removes dust and particles from the air,
Drain Pan: Collects and drains condensate water,
Casing: The housing that holds all components,
Control Valve and Thermostat: Regulates temperature and operation,
