Is what you are saying in contradiction to the well-known (to old-timers) Propane Refrigerator? Correctly termed "Absorption Refrigerator": http://en.wikipedia.org/wiki/Absorption_refrigerator But I have not been paying too close attention to the specific claims of the thread-carriers, so it may be you are denying the existence of something else.
