The vessel used as the Evaporator of a centrifugal chiller is described for different applications ranging from Brazed-Plate, DX Shell and Tube and the more normal Flooded Shell-and-Tube type. The market is water cooled centrifugal chillers, so the Condenser described will be a shell-and–tube vessel. Other condenser sources such as a once-thru system will be discussed and a comparison of pros and cons will be shown. The impact of oil and oil free systems and metering is compared along with existing ASHRAE Research Projects. A discussion on heat transfer and tubing is also included.
