<META content="Microsoft SafeHTML" name=Generator></P>
<DIV><FONT face=Arial color=#000000 size=2>Everyone, is there a relationship written down somewhere that removes fan energy from a heat pump COP value to develop a heating EIR? Something like the DX cooling EER equation that removes fan energy from EIR cooling values? It looks like the eQuest wizard is doing something like that when a heat pump heating COP is entered, but I am not sure what.</FONT></DIV><BR>_______________________________________________ Equest-users mailing list http://lists.onebuilding.org/listinfo.cgi/equest-users-onebuilding.org To unsubscribe from this mailing list send a blank message to EQUEST-USERS-UNSUBSCRIBE@ONEBUILDING.ORG </body>
