Types of Water Chillers
notes
Another standard that is related to chilled-water systems, ASHRAE Standard
15–1994, Safety Code for Mechanical Refrigeration, is intended to specify
requirements for safe design, construction, installation, and operation of
refrigerating systems. This standard covers mechanical refrigeration systems
of all sizes that use all types of refrigerants. Because absorption chillers use
water as the refrigerant, however, they are exempt from this standard.
For many chilled-water systems in which the chillers are located indoors, the
standard requires the refrigeration equipment to be installed in a mechanical-
equipment room. The requirements for this mechanical-equipment room
include refrigerant monitors and alarms, mechanical ventilation, pressure-relief
piping, and so forth.
