Storing the winter's "cold"
Posted: Sun Jun 08, 2008 12:18 am
I have been interested in the idea of storing the winter's "cold" as well as the summer's heat for a while now, and I had a specific question about the freezer mentioned on this website. While it may not be practical to reach sub-freezing temperatures with ice stored from the winter, have you ever considered a similar system to your freezer based on storing "cold" in ice? It seems to me that the heat absorbed by the ice's shifting from solid to liquid would greatly outweigh heat absorption of sub-freezing brine, but I don't really know how I would go about calculating the difference. I doubt that sub-freezing temperatures could be reached, but if one were only interested in refrigeration and air conditioning, I wonder if storing up large amounts of ice in the winter could prove economical on a residential or even commercial scale? I would be very interested to hear any thoughts or experience that you may have on this subject.
