Keeping interior cool

[L31MaxExpress]

One possibility in a truck would be to use a Tahoe/ suburban with rear air condenser it's a little thicker to provide extra heat dissipation for the rear air. In a regular cab or extended cab it might help marginally.

I put a parallel flow that is 1/2 the stock thickness in my van. It has lower high side pressure now than it ever has.

I'm going to put a valve in Frank because the blend doors don't seal well. No A/C yet.

Going to rebuild the HVAC box from the parts 'burb and put that in with all the A/C stuff too.

I don't think a swamp cooler would work too goo in Ohio with our high humidity.

That is interesting.

That is interesting.

102°F/35% humidity or there about. I am running a duramax fan blade and a 16" 3,000 cfm electric puller. Variable orifice tube in the front, expansion valve in the rear and R152a.

Is r152a a different refrigerant or was that a typo. Not to sound condescending or anything don't know much about refrigerants other than automotive.

Can you explain a variable orfice tube, I've never heard of that.

Yes its different. Its keyboard duster, canned air.

Its basically a pressure sensitive orifice tube that changes the size of the opening in response to pressure.
