Revision history [back]

I have created the suggested plot. It shows the volumetric air flow on the x-axis and the heating coil energy consumption on the y-axis. The plot is clearly different for each economizer control type (especially dry bulb vs enthalpy types).

My question is, how do I know if my results are acceptable knowing that we were expecting the heating energy consumption to be independent of the control type? Is it unrealistic to expect the heating to be independent of the economizer control type especially that the heating setpoint is the same for all economizer types?
