The purpose of this module is to assist in refrigeration heat reclaim calculations by providing hourly heating requirements for use in space heating or outdoor air preheat calculations. This module estimates space heating gains and losses relative to outdoor air temperature to calculate hourly space heating demand requirements that my be recovered via refrigeration heat reclaim. This method is intended for use for early estimation purposes only and will be more accurate for spaces with small amounts of glazing. To achieve a higher degree of accuracy, an energy model should be used to obtain these results. Yellow input fields are required inputs. Orange input fields are autocalculated and may be overwritten by the user.
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.
