ft. (4645 m2) are usually split circuit halocarbon systems (one or two air units traditionally connected with a close coupled air-cooled condensing compressor unit on the roof directly above). Also, refrigerated spaces over 200,000 sq. ft. (18580 m2) are traditionally ammonia, due to ownership costs. Those facilities in between 50,000 and 200,000

sq. ft. (4645 and 18580 m2) will require considerations and an understanding of an owner’s priorities and preferences. In order to properly answer the question of which system type is the best choice, an owner should make a comprehensive comparison of the alternatives based on a life cycle cost analysis. Additional items that should enter into this evaluation are: • Purchase or lease facility • New or existing facility • Future expansion considerations • Refrigeration system costs C Build cost considerations C Compressor room requirements C Power availability and cost C Water and sewage availability and cost • Equipment cost considerations C Initial cost C Operating cost C Preventative maintenance and service costs C Safety equipment provisions • Regulation compliance costs C PSM/RMP documentation and personnel training C Personnel safety equipment and training requirements C Liability and property damage insurance • Facility location and the surrounding areas C Off-site
