Double-walled heat exchanger risk analysis for Group B1 and Group B2 refrigerants.
Author(s) : BERGER A. E., FENTON D. L., KAITAY P. V., et al.
Summary
In compliance with ANSI/ASHRAE Standard 15-2001, Safety Standard for Refrigeration Systems, a large quantity of Group B1 or Group B2 refrigerant cannot enter the occupied space of a building. Instead, a secondary fluid must be used to circulate through the refrigeration system's components located within the occupied space. In typical systems, a single-walled liquid-to-liquid heat exchanger is used outdoors with an air coil in the occupied space. In this study, a double-walled heat exchanger is considered to replace these two components, where the double-walled configuration prevents leaking refrigerant from entering the occupied space of a building. Consequently, the double-walled heat exchanger located in the occupied space serves as a direct expansion coil. While any Group B1 or Group B2 refrigerant may be considered, ammonia, which is a Group B2 refrigerant, became the focus of this study due to the availability of commercial absorption units.
