The Efficiency Tango: A Deeper Look at ... - Alternative Energy Stocks

There are three 7 Series models and two Trilogy 40 models, each of which was tested at full load and part load, under two types of conditions. The “ground water” series are when the ground water is pumped up out of the ground for heat exchange; the liquid water helps heat transmission and results in a higher rating. The “ground loop” series is representative of the much more common installation, when an antifreeze fluid (usually propylene glycol) is pumped through the geothermal loop, which results in relatively lower efficiency (although still much higher than other types of heating and cooling equipment.) Even in ground loop conditions, different heat exchange fluids will result in different effective inefficiencies. The partial-load results are the sets of two or three smaller bubbles to the right (and a little below) sets of larger bubbles of the same color.
