Silly Wife question:

[Phaseolus]

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?

That’s the whole damn reason for the cab recirculation switch that activates when you hit max a/c driver!

 

[BrentD]

Of course you are wrong. Your wife said so. That's all there is to it. Laws of physics are suspended when ever a wife's opinion is involved. This is pretty elementary, really.

 

[duckhunt]

I would think recirculate would be cooler.

All you need to know right there.

 

[Gerald Martin]

Do you want to be right or do you want to be happy?

I 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.

Huh? mtmuley

 

[bobbydean]

As already reported, the wife is always right!

 

[Salmonchaser]

I don't often agree with MTMuley, I'm with him on this one.

The Gospel according to BrentD. Spot on observation/advice.

 

[crock239]

You're both right.

When u first get in the 125 degree vehicle in the parking lot, the AC will blow colder from outside air. (She's right.)

Once the temp inside the car gets to outside air temp or below, AC will blow colder on recirc. (You're technically correct...but she's still right!)

You're welcome.

 

[FI460]

Whatever she says, man.

 

[BAKPAKR]

When I opened this thread, I thought it was going to be about silly wives, not that I have any expertise in that area…

 

[R.K.]

@crock239 got it right.

Best of both worlds would be you open the windows to vent the car before you even get in

 

[VikingsGuy]

@BrentD has the technically correct husband answer.

That aside, what she may be experiencing could be explained by humidity differences between the air sources. Humidity effects perception of temperature.

 

[JEL]

Huh? mtmuley

I was thinking exactly the same thing. Lol.

 

[hank4elk]

Seriously? Your asking just showed your ignorance. I know this and have never been married.

Wow, we are truly in the depths of the off season...
