Guide for the selection of supermarket refrigeration systems
- Foster-Miller, Inc., Waltham, MA (USA)
This report presents an evaluation of supermarket refrigeration involving the use of conventional and multiplex compressor systems. Computer simulations of these systems were performed for six representative sites. The performance predictions generated in this fashion were tabulated to allow hand calculation of electric costs for any prevailing electric rate schedule. A methodology was also developed to allow economic assessment of the conventional and multiplex systems and of various enhancements employed with the multiplex system. The results of the evaluation showed the multiplex refrigeration system produced a reasonable payback for all sites examined, depending upon the enhancements employed. System features that had the greatest impact on payback were heat reclaim, hot gas defrost, and floating head pressure. 25 figs., 28 tabs.
