Oh, indeed I was wrong; COP of Peltier elements is much higher than I had gleaned from online charts, not the order of 0.03 (3%) but can easily reach values above 1.0 (100%) and be e.g. 0.5 (50%) at ΔT = 30C, enough for a home fridge. Still a bit far from compressor-based designs, but not negligible, and almost doubling the efficiency is indeed a serious advance. |
