Does anyone know the BTU quantity of the
air conditioner of the typical W124 vehicle? ie how many
BTU do the air conditioner of that car put out? I guess
it would be a lot less than that of the household unit.

Typically then how much/many BTU do most vehicles air cond.
put out?
TIA

I can't address the 124 specifically, but I remember seeing charts in a book a few years ago which described BTU capacity of automotive A/C systems using various sizes of York compressors. The figures ranged from 15,000-30,000 BTU if I remember right. The "ton" rating for A/C is equivalent to 12,000 BTU, so your typical car A/C is the equvalent of a pretty good sized central home A/C unit. Remember that cooling a car interior is much harder than a similar sized space in a home because of engine heat, varying compressor shaft speed, and most of all the vast expanse of glass that can't be covered with curtains, venetian blinds, etc.
