CHAPTER 2
REFRIGERATION SYSTEM DESIGN REQUIREMENTS
2-1
GENERAL. Design refrigerated systems for cold storage to provide
safety, economy, and reliability. Refrigeration design is a specialized field. The design
of cold storage refrigerated systems should be performed by an experienced
refrigeration design engineer. A "plan and specify" or a "design-build" arrangement can
perform the refrigeration design. Design-build has been the trend of the refrigeration
industry.
In many cases, equipment manufacturers have significantly supported the
refrigeration design.
2-2
SAFETY. Safety is paramount. Safety is critical in the design,
construction and operation of refrigeration systems for cold storage, especially with
ammonia systems. Refrigeration system's safety standards must meet ASHRAE 15.
ASHRAE 15 specifies safe design, construction, installation, and operation of
refrigeration systems by establishing safeguards for life, limb, heath and property and
prescribing safety standards. This includes, but is not limited to, occupancy
classification, restriction on refrigeration use, installation restrictions, design and
construction of equipment and systems, and operation and testing.
Consider equipment selection and its placement for safe accessible
maintenance. A safety review of the engineered design and equipment layout is
recommended with participation from the owner's site operations and maintenance
(O&M) entities.
The designer is required to perform a system safety plan and hazard
analysis. Personnel safety measures are required as part of the facility design. Refer
substances requiring consideration may include, but are not limited, to the following:
Ozone depleting gases
Greenhouse gases
Ammonia
Pressurized gases
Flammable gases
Hazardous gases
Hot gases and equipment
Electrical power
