Making these air conditioning systems more energy efficient is by far the quickest, most affordable and most effective way to reduce your CO2 emissions and lower your energy bill.

In the light of today’s energy problems, global warming and since older and not so advanced aircon systems will be in use for many more years in large numbers, we have analysed various existing energy saving techniques for air conditioning systems and reviewed plenty of earlier research. The conclusion was that detecting the system’s efficiency and switching the compressor accordingly is probably the only effective, pragmatic and economical measure to achieve a better energy efficiency. There is no „free lunch“ with any retrofit, but these savings come at no or only very small decreases in cooling comfort.
