[DML] Re: A/C Cycling



Actually "sophisticated valving" isn't new at all. They're known as
Thermal Expansion Valves. Every household refrigerator and central or
window A/C unit has had them for decades. Most car manufacturers other
than GM used them too. They yield much smoother and more precise freon
metering than a fixed orifice tube. One of my long term projects is to
convert my DeLo to such a system. I can feel my OEM cooling fans cycle
even at highway speeds!
