Anyone know of study made in controlled conditions of two air-conditioners of same manufacturer, of same size, with same parts used with only difference in inverter driven compressor and normal ON-OFF compressor respectively. I mean same compressors used of same COP and EER at 50 (60) Hz, but one is powered and controlled by inverter and other is controlled by regular ON-OFF cycle.
I would like to see that comparison in energy savings, since claims of 30-50% in savings are way to much for my understanding of physics and construction of air-conditioners.
As far as I know, energy is consumed by air conditioned space and air-conditioner task is to convert electrical energy in to "cooling" energy or heat. Difference in power consumption can be accomplished only by difference in COP and EER off used air-conditioners. Since I strongly doubt that inverter driven and on-off controlled compressor (i mean physically same one) can have that much (30-50%) difference in COP and EER i don't see how can we achieve such savings as declared in many AC manufacturers commercials.
Therefore I would like to see study in controlled conditions where only difference between two samples is driving principle of same compressor (ON-OFF vs INVERTER)
