Will see if I can elicit comment on this topic from eQuest's dynamic, talented
and decidedly underappreciated developers, who tirelessly toil day and night on
our behalf. Perhaps we can show our appreciation for them by all lobbying
our local Mitsubishi / Daikan reps to secure funding for a port-to-eQuest
effort. After all, updating to eQuest it seems would be in the
manufacture's best interests, with usage of variable refrigerant flow systems
gaining traction in the marketplace.<br>

As far as I know you cannot do it in DOE2 directly, but a quasi DOE2 approach
would be to calculate the hourly system loads using DOE2 and calculate VRV
energy consumption using spreadsheet calculations. You will have to create a
regression based model to calculate the energy consumption as a function of the
capacity and outdoor air temperature (The data is available on Mr. Slim
website). Once you are sure the model is working correctly (be sure to put
limits on your equations for out of range data) you can use the hourly weather
boundary conditions to calculate the annual energy consumption. <br>
<br>
If you are doing code compliance using eQUEST you can calculate the average
calibrated EER using the above methodology and use it as a DOE2 input. <br>
