Résumé

Develop Test and Rating Methods for Seasonal Performance of Water Source Heat Pump equipment covered by current ISO 13256-1, ISO 13256-2 standards. Details related to full and part load testing shall be included or aligned with updates to the current ISO 13256 standards. Rating methods and applicable calculations shall be included or referenced. The intent is for all of the seasonal calculations of these standards be based upon the ISO 13256-1 or -2 performance maps of source and load temperatures so that additional testing beyond 13256 will be reduced or even eliminated.
