Fuel cooling system and method

A temperature controlled cargo container comprising:

• a plurality of walls defining an interior space configured to store a cargo;
• a refrigeration unit configured to circulate a refrigerant;
• a bypass cooling circuit fluidly coupled to the refrigeration unit;
• a power generation system operably coupled to the refrigeration unit, the power generation system including a fuel tank fluidly coupled to an engine;
• and
• a fuel cooling circuit fluidly coupled between the fuel tank and the engine, the fuel cooling circuit thermally coupled to the bypass cooling circuit and configured to cool a fuel by thermal exchange with the refrigerant.

A method of fabricating a fuel cooling system, the method comprising:

• providing a refrigeration unit configured to circulate a refrigerant;
• providing a bypass cooling circuit fluidly coupled to the refrigeration unit;
• providing a power generation system operably coupled to the refrigeration unit, the power generation system including a fuel tank fluidly coupled to an engine;
• providing a fuel cooling circuit fluidly coupled between the fuel tank and the engine;
• thermally coupling a heat exchanger between the bypass cooling circuit and the fuel cooling circuit to provide thermal exchange between the refrigerant and the fuel;
• and
• operably coupling a controller to the bypass cooling circuit and the fuel cooling circuit, the controller programmed to selectively operate between a first mode and a second mode, wherein in the first mode the refrigerant bypasses the bypass cooling circuit and the fuel bypasses the fuel cooling circuit, and wherein in the second mode the refrigerant is circulated through the bypass cooling circuit and the fuel is circulated through the fuel cooling circuit.
