1. A refrigeration system for an intermodal container, comprising:
a) a refrigeration unit located within the intermodal container, the refrigeration unit comprising a compressor, a condenser, an evaporator, and a power connector for connecting the refrigeration unit to a power source;
b) a first plurality of air ducts configured to convey pressurized air from the refrigeration unit to a plurality of food carts within the intermodal container, the first plurality of air ducts including a plurality of air outlets configured to interface with the plurality of food carts, wherein the first plurality of air ducts includes a first pair of air ducts that extend in opposite directions to the right and left of the refrigeration unit;
c) a second plurality of air ducts configured to convey air from the plurality of food carts to the refrigeration unit, the second plurality of air ducts including a plurality of air inlets configured to interface with the plurality of food carts, wherein the second plurality of air ducts are connected to ends of the first plurality of air ducts and are located below the first plurality of air ducts such that the plurality of air inlets is located below the plurality of air outlets, wherein the second plurality of air ducts includes a second pair of air ducts that extend in opposite directions to the right and left of the refrigeration unit, and wherein the second plurality of air ducts merge into a single duct upon meeting the refrigeration unit;
d) wherein each of the plurality of air outlets and air inlets includes a spring-loaded valve configured for automatically opening when a food cart of the plurality of food carts rests against the valve, and for automatically closing when said food cart no longer rests against the valve;
e) one or more fans configured for circulating air within the first and second plurality of air ducts; and
f) an ultraviolet (UV) light sterilization system located within the first and second plurality of air ducts;
