Heatrecovery - Not working

asked 2020-04-06 22:06:52 -0500

Currently, within my model, no heat recovery value is being registered when I run my model within the 'End Uses' table in the Results Summary (I can not currently upload any images).

Energy recovery ventilation (ERV) I am using HeatExchanger:AirToAir:SensibleAndLatent to model the heat recovery within my VAV system

Only the enthalpy wheel motor is included under heat recovery if you set the type to 'enthalpywheel' in the HeatExchanger:AirToAir:SensibleAndLatent object. Otherwise, all energy in your ERV is from the supply and exhaust fans which are included under the Fans end use. You can set an energy use subcategory on these fans to split out which ones are in ERVs vs. others in the building.
