Carrier TDP 623 Commercial HVAC chiller Equipment Water-Cooled Chillers
Technical Development Programs (Carrier TDP 623 Commercial HVAC chiller Equipment Water-Cooled Chillers) are modules of technical training on HVAC theory, system design, equipment selection and application topics. carrier TDP are targeting the engineers and designers who wish to develop their knowledge in this field to effectively design, specify, sell or apply HVAC equipment in commercial applications.
Water-cooled chillers range in size from small 20-ton capacity models that can fit in an elevator to several thousand-ton models that cool the world’s largest facilities such as airports, shopping centers, skyscrapers, and other facilities. This TDP module will review all sizes of water- cooled chillers, but will contain more information on the larger chillers in the range of 200-ton and upward. Screw and centrifugal compressor water-cooled chillers tend to be the most popular designs for larger commercial applications, while scroll and reciprocating compressor chillers used on the smaller ones. Air-cooled chillers are covered in a companion module,Carrier TDP-622.

This Carrier TDP module on water-cooled chillers starts with a history of the first centrifugal chiller and describes the first applications for early water-cooled chillers. After a discussion of the relative merits of water-cooled chillers, the refrigeration cycle for a water-cooled centrifugal chiller is explained using pressure-enthalpy diagrams.
We will examine the major components used in water-cooled chillers such as evaporators, condensers, compressors, and metering devices. The types of chiller starters and their applications also discussed.
