[Equest-users] PTAC Curve

[Lee Chorney]

Hi Everybody,

Does anyone understand the heating EIR curves used for PTACS in Equest? It
is the "DX-Heat-EIR-fEDB&OAT" curve. I calculated the curve using excel
(see attached spreadsheet) and found as the outside air gets colder the
efficiency of the heating curve increases. Does that make sense to anyone?

Thanks in advance,

Lee
