Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.
Chillers
In this system Chilled water is for condensation, in Chiller Shell & tube Evaporator are used. Evaporator may be DX type or Flooded type.
