The paper discusses equipment configurations for the use of ammonia in supermarket refrigeration applications. This paper identifies the optimal design for ammonia-secondary fluid systems and compares their performance to that of R22 systems. Three methods of staging the compression were compared for both refrigerants. Six secondary fluids were evaluated for use with ammonia in a supermarket system. Overall system performance of the ammonia-secondary fluid refrigeration system is governed by a large set of design parameters. The influence of these parameters on overall system performance was studied systematically. From this parametric study, design rules were developed, leading to optimum ammonia-secondary fluid systems.
