- Scoundreller 8y agoSmall boats used systems like this: freezing blocks of ice to provide convective cooling to a cooler so that things stay cold without the engine running. A lot of people hated them enough (and the gas used while sailing) to replace it with solar based systems.
- edaemon 8y agoRegular refrigerators use the same principle, albeit with a mechanism much simpler than a heat pump. They have holes between the freezer and refrigerator compartments and use a fan to push cold air from the freezer to the refrigerator. A heat pump would make that exchange much more efficient.
- JoeAltmaier 8y agoI doubt that heat pumps could be more efficient than direct exchange of cold air?
- edaemon 8y agoThere are periods where you don't want the cold air to move into the refrigerator. Direct exchange allows the cold air to move around at all times -- regular refrigerators just turn a fan on and off, but some heat is always exchanged through the holes. A heat pump would just make the exchange more controllable.
