What we claim as new and desire to secure by Letters Patent, is:-

1. A refrigerator comprising a cabinet having a compartment through which air from outside of said cabinet is circulated to be cooled, said cabinet including a chamber for a low temperature refrigerant arranged to cool a liquid heat exchange agent, means for circulating said heat exchange, agent through said compartment for cooling air, and said cabinet also having a storage chamber for food stuffs and means for cooling said storage chamber by said heat exchange agent independently of cooling air in said compartment.

2. A refrigerator comprising a cabinet having a compartment through which air from outside of said cabinet is circulated to be cooled, said cabinet including a chamber for a low temperature refrigerant arranged to" cool a liquid heat exchange agent, means for circulating said heat exchange agent from said chamber and through said compartment for cooling air, and said cabinet also having a storage chamber for food stuffs and means for circulating said heat exchange agent from said chamber through said storage chamber independently of said circulation through said compartment.
