<p class="MsoNormal">Hi Christophe,<o:p></o:p></p>
<p class="MsoNormal">I agree that there is no obvious way to add supplemental heat to VRF systems in DOE-2.3 for simulating cold climate performance. If you are designing a system and the simulation is showing unmet hours, you could change the capacities of
indoor and outdoor units. If it is an existing system and/or the system capacities are locked, you could add heat using baseboards, a DOAS unit, or an additional terminal unit in an adjacent zone separated by an air wall. You can add energy to represent electric
resistance heat in the Miscellaneous tab of the Condensing Unit (as crankcase or auxiliary power) but it will not add actual heating capacity to the unit.<o:p></o:p></p>
