NREL: Initial Data from 13 Cedar VA Hybrid Mini-Spit System

NREL: Initial Data

13 Cedar Hybrid Mini-Split System

(Hybrid = Partly Ducted, Partly Ductless)

Greetings PlanetSavers,

Tonight we will look at the initial results of 15 days of hot weather in the Cedar St. Lab House.  NREL is monitoring this project and has kindly provided us with loads (overloads, actually) of data. We have the mountain of data distilled down into some useful charts and graphs and for you “Bottom Liners” we have the total cost of cooling extrapolated.

We  will analyze what installation factors affect the results we see. Like duct sizing to each room and how that shows up in temperature differentials. This project is interesting because it does not have door actuators and the doors are Closed. It’s a good test of the Tamarack Return Air Path door bottom grilles.

We will also answer the question, “If you were doing this project over again, what would you do differently?” Of course the answers on this one can only be finalized after we go thru the winter with the system as it is.
