  • Design Temperature Difference for Chillers - HVAC School

    Nov 13, 2018 · The numbers for chilled water (44 out 54 in) and condenser water (85 out 95 in) are industry-standard values at full load conditions. Most chillers, regardless of manufacturer, will have a 10°F delta T on the cond and evap. Machines that operate outside of those ranges are chillers that were ordered specifically to provide a lower temp or
