UFC 4-826-10
10 July 2002
CHAPTER 1
INTRODUCTION
1-1
PURPOSE AND SCOPE. This UFC provides general criteria for the
design of new refrigeration systems for cold storage. This document, and all
references contained herein, provides guidance to the DOD. They may also be useful
to commercial firms engaged in the design and construction of refrigeration systems for
cold storage for DOD facilities.
Note that this document does not constitute a detailed technical design,
maintenance or operations manual. Rather, its purpose is to identify and utilize the
most appropriate Non-Governmental Standards (NGS) by specifying the refrigeration
industry codes and standards that best apply, and to include the Tri-service's specific
requirements.

BACKGROUND. The purpose of refrigerated systems for cold storage is
to maintain or extend product life. Refrigeration systems for cold storage are applied to
processing, manufacturing, and warehousing food, biomedical materials, ice
manufacture, and other uses; but the largest application is for the refrigeration and
freezing of foods. Refrigerated systems provide much lower temperatures than comfort
air conditioning systems. The design, selection, and construction of a refrigeration
system is different and can be more intensive than that for a comfort air conditioning
system. For this reason, the refrigeration industry has evolved into a separate and
distinct industry.

PRIMARY VOLUNTARY CONSENSUS STANDARD REFERENCE. This
UFC adopts the latest edition of American Society of Heating, Refrigeration, and Air
Conditioning Engineers, Inc. (ASHRAE) Publications listed below as the primary
voluntary consensus standard for the Tri-services refrigeration systems for cold storage.
ASHRAE Handbook Refrigeration

SECONDARY VOLUNTARY CONSENSUS STANDARD REFERENCES.
This UFC adopts the latest edition of the standards listed below as the secondary
voluntary consensus standard for the Tri-services refrigeration systems for cold storage.
ASHRAE Standards encompass halocarbon and ammonia refrigeration systems.
International Institute of Ammonia Refrigeration (IIAR) refers to ammonia systems
exclusively.
