ttystikk , when i compare it with a split unit,
-A split unit cools the hot gas with air (outside)
-The Opticlimate cools the hot gas with water.
Water takes up energie much better than air, making it 10%more efficient.
Here a little piek inside
I don't reuse the warm water. I know people that use it for underfloor heating or heating up a boiler. You can also run it trough an air/water exchanger and heat your house with it. In spain and Italie growers pump water from there swimmingpool into the unit. The warm water from the unit goes back to the swimmingpool making the growroom cool and the pool hot ;)
With a pump the delta-T is smaller. Water entering the unit can be up to 86gr. The water leaving the unit is than 95gr. The swimmingpool has to cool down the water 9gr. The pool must be in/underground to loose the heat to the earth.
Hope this makes sense to you.....
