I live on the Washington coast and summer days here seldom exceed 75F and night temperatures are generally between 20 and 45F year round.<br /><br />I built an insulated (4" foam) pantry inside the north side of my garage and plumbed a thin 6" aluminum duct outside the building where it is always in the shade. The duct runs from near the floor inside the panty, through the wall, up outside the garage, then back inside at to the top of the pantry. It pumps naturally. The heat in the air radiates through the duct wall, cooling as if falls, pulling more warm air in from the top and dumping the cooled air back into the bottom of the panty. A closed cycle California cooler. I wanted closed cycle to avoid pulling in humidity always present here on the coast. Temperature inside the panty has never exceeded 44F over the last two years. I put a thin plastic film flapper over the bottom exit to prevent reverse flow when the temperature outside is higher than inside. Basically it gather the cold night temperatures and stores them during the day. During the winter when days are below 40 and nights are below freezing, I seal it off to prevent bulk freezing of everything in the pantry.Nicusnoreply@blogger.com
