A water chiller system consists of two major loops or circuits. These are the chilled water loop and the refrigeration loop. The component that delivers cooling is the refrigeration loop. The thermodynamic processes take place here. The chilled water loop, on the other hand, is a distribution system that provides cold water to consumer units. Heat transport is the primary mechanism at play in this system.

4. Air-cooled
Water Chiller
• Finned coils are common in air-cooled condensers.
• This raises the condenser's surface area in contact with the
air.
• To increase heat transmission even further, one or more
fans are utilised to blow air over the finned coil.
• The quantity of heat rejected by an air-cooled condenser is
determined by the rate of airflow over the coils as well as
the temperature of the air at the dry-bulb.
5. Water-cooled Water Chiller
Water-cooled condensers typically operate with a cooling tower.
Cooling towers are heat exchangers, but instead of the usual
conduction-convection type of heat exchangers, it generates cooling
by bringing water and air into contact.
They supply cooling water to the condenser unit which is used to cool
the refrigerant.
6. Centrifugal
Water Chiller
• A rotating water chiller is equipped with a centrifugal compressor.
• By increasing the kinetic energy of the gas, a centrifugal compressor
raises its pressure.
• The fluid is then slowed in order for its kinetic energy to be
converted to potential energy in the form of static pressure. They are
dynamic-type compressors due to their operation philosophy.
7. Screw Water Chiller
• A screw compressor is used by this kind of chiller, often
referred to as helical-rotary water chillers, to supply
mechanical work for its vapour compression cycle.
• An example of a positive-displacement, rotary compressor
is a screw compressor, which generally has two helical
screws acting as the rotors. The refrigerant is compressed
by being trapped in the crevices between the rotor's
threads.
• These cavities' volume gradually shrinks, resulting in a rise
in pressure.
8. Scroll Water Chiller
• Small cooling load applications are where scroll
chillers are most frequently employed.
• One chiller package may have one or more scroll
compressors to boost its capacity.
• They have COPs that are equivalent to screw kinds
in terms of efficiency. Several refrigerant control
techniques, including speed control and variable
displacement control, are available for use in
situations with fluctuating cooling loads.
9. Reciprocating
Water Chiller
• This water chiller uses a reciprocating piston or
plunger to draw and compress the refrigerant.
Because of their nature of producing
compression, they are also classified as positive-
displacement compressors.
• A reciprocating water chiller is now becoming
an obsolete chiller technology because of the
drawbacks of its compressor.
• Reciprocating compressors have a noisy
operation, poor reliability, and short service life.
The only advantage is their affordable cost.
