That’s the whole damn reason for the cab recirculation switch that activates when you hit max a/c driver!My Wife has become convinced that the air conditioner blows colder when the vent brings air in from the hot outside. The laws of physics seem to me to mean the air will be colder on recirculate. Am I wrong?
Huh? mtmuleyI might screw up my undergrad Thermodynamics here but you can tell your wife that she may be right in the fact that the rate of cooling will be higher with hotter outside air due to the higher delta of temperatures. You can juxtapose your positional authority by saying that the energy efficiency (cost savings) should be greater with the recirc. Someone who has been through their engineering science courses more recently might have a better answer.
