Is this correct from a thermodynamics perspective? Both a fridge and an A/C are heat pumps, so the amount of energy they use is proportinal to the difference between the two temperatures they pump between. This means that if the heat sink for the fridge is outside (where it is much hotter) then the fridge needs to work that much harder to keep the inside chamber cold at a certain temperature, negating the energy savings of the A/C unit. There is no free lunch in physics.
