Walter- You: "Sort of like the cold equivalent of trying to weld with a match?" Exactly. You will note that CA refrigeration is always used for very-well insulated spaces, which don't get opened and closed much. The cooling ability of this type of system is limited, but useful for refrigerators. Your van, on the other hand, is a big greenhouse, with little insulation, and a hot radiator and motor in close proximity to the relatively un-insulated metal of the vehicle. You would need the CA system off an old battleship to cool your van. G. Matthew Bulley Bulley-Hewlett & Associates www.bulley-hewlett.com Cary, NC USA 888.468.4880 tollfree

Think of it, you could have ac while parked, no compressor to steal power from the engine, no ozone depleting chemicals. The cabinet in the back where the curtains are stowed could accomodate it. Propane fired (second vent at the back of the van) and use small blowers over the evaporator without too huge a draw on the battery. After poking about on the web I've found lots of info on how the system works in refrigerators and freezers, but have not found any mobile AC units. Am I missing something? Sort of like the cold equivalent of trying to weld with a match? Anybody BTDT? Any rocket scientists out there with some spit and chewing gum? Walter |
