The numbers don't quite add up, the 4.55kg @ 85% would yield .8kg @15%
but 2.2kWhr on this example looks like a coefficient of perfomance of
better than 2.3MJ/kg of water removed.

Consider that there is a major difference in energy cost between
electricity for the compressor and the same amount of heat, to compare
like with like you need to distinguish between the use of high grade
electric energy and an air dryer.
