An Introduction to Refrigeration Systems Design for Professional Engineers: 25

his section addresses the general requirements for the design and selection of a refrigerated system for cold storage. ASHRAE Standards and Handbook are the basis for refrigeration system design, selection, installation, testing, and operating. For ammonia systems, the standards of the International Institute of Ammonia Refrigerators (IIAR) will apply, and if more stringent than ASHRAE Standards, IIAR will prevail. Design new refrigerated facilities to meet the considerations for building design that are provided in the refrigerated facility design chapter of ASHRAE Handbook - Refrigeration. Cold storage facilities held below freezing can cause under floor ice formation, resulting in floor upheaval. Design sub-floor freeze protection for facilities that are held below freezing, such as air duct systems, electrical heating systems, or heated pipe grids. These systems are detailed in the above-mentioned chapter. Comply with all ASHRAE Standard 15 in its entirety, including but not limited to equipment placement, ventilation design, door and passageway restrictions, refrigerant monitoring, flame devices, pressure relief and purge piping, refrigerant piping, signs, self-contained breathing apparatus (SCBA), and miscellaneous installation restrictions.
