HVAC Chiller Plant Design Standards As Per ASHRAE Guidelines



Description
The chiller can be water-cooled, air-cooled or evaporatively cooled. The compressor types typically are reciprocating, scroll, screw or centrifugal. The evaporator can be remote from the condensing section on air-cooled units. This has the advantage of allowing the chilled water loop to remain inside the building envelope when using an outdoor chiller. In applications where freezing conditions can be expected, keeping the chilled water loop inside the building avoids the need for some form of antifreeze.

There can be multiple chillers in a chilled water plant. The details of various multiple chiller plant designs will be discussed in future sections.

The chilled water flows through the evaporator of the chiller. The evaporator is a heat exchanger where the chilled water gives up its sensible heat (the water temperature drops) and transfers the heat to the refrigerant as latent energy (the refrigerant evaporates or boils).
