Chilled Water System

Chilled water system is using refrigerant to deep cooling water & use water to cool the air through air side machines (FCU, AHU). It is not using refrigerant direct to cool air like other DX systems.

Types

Air Cooled – Chilled Water System
Water Cooled – Chilled Water System

Components of System

Chillers
Pumps
Cooling Tower (In Case Water Cooled)
Chilled Water Piping
Accessories (Air Separator, Chemical Dosing)

Where to use:

For High Capacities 500 TR & Higher
For Variable Heat Load
For Industrial Areas
For Big Commercial buildings
For High Rise Buildings

VRF SYSTEM

VRF SYSTEM

VRV system is like DX system but as big as chilled water system. It has just 1 combination of outdoor could supply & feed refrigerant to multiple indoor units or AHUs. It uses copper piping network to connect this just 1 outdoor or its combination to multiple indoor units with various shapes

Types

It has only 1 type air cooled VRV outdoors connected to multiple indoor or AHUs

Components of System:

Outdoor Condensing units
Piping network
Y-Branches
Control Loops
Indoor units

Where to use

  • For High Capacities 500 TR & Higher
  • For LEED Building
  • For Low Power Consumption
  • For Variable Heat Load
  • For Industrial Areas
  • For Big Commercial buildings
  • For Very High-Rise Buildings
