Why are eutectic refrigeration systems so efficient on power?
Refrigeration systems are more efficient when heat rapidly saturates the evaporator, and as the eutectic evaporator is in a liquid it can rapidly absorb heat and lower temperatures. By comparison aluminum plate evaporators cooling the air run at much less efficient temperatures where the refrigeration systems coefficient factor is very low. (Put a hot can of drink in ice water and another on the shelf of a fridge at the same temperature. You will be drinking the one from the ice water ten times sooner!) So not only is the system operating in much more efficient conditions, it does the job so much quicker and with the eutectic hold-over, runs much less often. An aluminum evaporator plate system will typically cycle say 10 minutes on 20 minutes off. (Two cycles per hour or 48 cycles per day while the Eutectic system runs once per day or twice in hot conditions.) Back to Top Q27: But aren’t aluminum plate evaporator systems cheaper. A: Yes they are, but try buying one with a decent warran
