1. Insulation
Purpose: Reduces heat loss or gain, increases energy efficiency, and prevents condensation.
Types: Thermal insulation (fiberglass, foam, rock wool), acoustic insulation.
Application: Used on ducts, pipes, equipment, and building surfaces.

2. Duct
Purpose: Distributes air (supply, return, exhaust) from HVAC systems throughout the building.
Material: GI sheet (galvanized iron), aluminum, flexible duct, or insulated duct.
Design: Includes elbows, dampers, grills, diffusers, and volume control dampers.

3. AC (Air Conditioner)
Purpose: Cools or conditions the air to maintain desired indoor temperature and humidity.
Types:
Window AC
Split AC
Cassette AC
Ductable AC
VRF/VRV systems (for large commercial spaces)

4. Chiller
Purpose: Produces chilled water used to cool air in large HVAC systems.
Types:
Air-cooled Chiller: Uses air to remove heat.
Water-cooled Chiller: Uses water (via cooling tower).
Application: Used in malls, hospitals, industrial plants, commercial buildings.

5. Pump (Pumb)
Purpose: Circulates chilled water, hot water, or condenser water in HVAC and plumbing systems.
Types:
Centrifugal pump
Inline pump
End suction pump
Use: For chilled water loops, condenser water loops, and booster systems.

6. Additional MEP Items (Quick Mentions):
AHU (Air Handling Unit): Conditions and circulates air as part of HVAC.
FCU (Fan Coil Unit): Smaller air conditioning unit used in rooms/zones.
Cooling Tower: Used with water-cooled chillers to reject heat.
Piping: Carries water, refrigerant, or gas (GI, copper, HDPE, etc.).
Valves & Fittings: Control flow, direction, and pressure of fluids.
