The refrigeration unit further including an interior lining that includes a bottom planar-like interior surface and a top interior surface facing the bottom interior surface. The refrigeration unit including a bottom base, wherein the bottom exterior surface is positioned between the bottom base and the bottom planar-like interior surface. The refrigeration unit includes a condenser positioned between the bottom base and the bottom exterior surface, wherein the refrigeration unit is oriented within a gravitational field generated by the Earth so that the gravitational field flows from the top interior surface to the bottom base. ## Claims ### Claim 1 A refrigeration unit, comprising: an exterior lining, comprising: a first exterior side surface;
