what surprises me is that very early gas or oil fired refrigeration units were rather common (relative to the fact that refrig was rather uncommon prior to the war) but never applied to automotive or other environments for human habitation.

Two very large air conditioning systems that come to my mind prior to WW II were the huge dining rooms on the RMS Queen Mary of 1936 and SS Rotterdam of 1938. I've heard that they were ammonia systems powered by waste flue gases but have never been able to come across any real documentation. Carrier was very well-established by then, perhaps they were the supplier...?

Again I digress....but some details on these large scale systems would be interesting, at least to me and perhaps to others.

PS - the QM system is described as a "steam injection/vacuum evaporator" system, whatever that means.
