Refrigeration System Front-End Spreadsheet
The purpose of the Refrigeration System Front-End Spreadsheet is to provide a tool for a mechanical designer to use for rapid, robust calculation of refrigeration system performance. The results of the spreadsheet are intended to be used with the accompanying Refrigeration Playbook spreadsheet tools for determining the feasibility of heat recovery system integration. This tool assumes that the refrigeration system being analyzed is a system with a single suction group. Condensers may be selected as air-cooled, evaporative-cooled, or hybrid with constant speed or variable speed fan control. For more complex systems, the designer may consider calculating each suction group separately and combining the results where loads and massflows are additive with a weighted average of discharge temperatures.
This spreadsheet is designed for use with the Refrigeration Playbook: Heat Reclaim report (www.nrel.gov/docs/fy15osti/63786.pdf). Please note that this calculator is not currently approved for use on Mac computers.
