Patent

CA 2354115

A conduit running from a freezer or refrigerator to the outside air with a fixture at each end, uses cold outside air to keep a refrigerator or freezer cool, with less dependency on energy usage. Cold air from the outside is allowed to enter the pipe through the fixture and because cold air drops and the pipe its self slopes downward, the cold air continues through the pipe, through the inside fixture, and into the freezer. The temperature outside has to be as low or lower than the desired refrigerator temperature in order for it to be effective.
