Types
Air cooled chillers, the most common chiller
type, require little maintenance. However, because of the
need for high condensing temperatures ranging from 120°
F to 140° F, air cooled chillers require more power to
operate.
Central chilled water units consist of air handling units
fitted with chilled water coils and are utilized in air condition
systems.
Dedicated-process chillers operate year-round and are designed
to provide specific, capacity-matched cooling protection and
proper temperature/water flow. Dedicated-process chillers
are the best choice for medical applications.
Evaporative cooled chillers are uncommon but highly efficient
liquid chillers. Evaporative chillers maintain the lowest
condensing temperatures, which range from 85° to 105°
F.
Fluid chillers provide process cooling using a secondary
fluid.
HVAC chillers are often installed outside and are available
in centralized and modular designs. HVAC chillers are used
in industrial and commercial environments.
Machine tool chillers lower the temperature of coolant that
is used in the cutting zone and recirculate it back to the
machine tool in a closed-loop system.
Medical chillers are Self-contained chillers with higher
pressure pumping, temperature stability and microprocessor
controls.
Portable chillers are self-contained units and are useful
in small and/or dedicated applications.
Recirculating chillers constantly circulate coolant in a
closed loop, retaining high efficiency without wasting water.
Water chillers consist of a compressor, condenser and chiller
with internal piping and controls all contained within a single
unit. The term "water chillers" refers also to an
overall package that includes a refrigeration plant, water
chiller and air or water cooled condenser.
