OK, question for you "A/C" experts
OK gang,
This is for you EXERTS that know air conditioning and, all aspects of it. Below is a picture of the A/C condenser and, the electric fan that provides air for cooling of it. You'll see that the fan, has NO SHROUD (that is of value). Now, in most, if not all, radiator situations, on just about every car, truck, air plane, space ship etc. that have ever been built, there is a real shroud that encompasses the entire radiator fin area and, it's also usually very close to the tips of the fan blades.
All that means that, the fan can pull (or possibly push) air through the fins, ALL THE FINS, making the cooling effects much more efficient, than what I think is going on in the picture below.
In reality, if you look at the picture closely, it appears that I may have as much as 25-30% of that condenser that it not actively having air forced through it, due the fact that there's no real shroud involved.
Our coach, an '04 Itasca Horizon 36GD with the C-7 330HP CAT, has basement air conditioning style on the passenger side rear compartment and, the dash air system on the same rear compartment, on the drivers side. The dash air conditioning system does work and, it works just OK. I just had it evacked (is that a word?)and re-charged. The folks that did the work stated that there is no leaks.
So, I'm wondering, does anyone think that, it would be worth the effort to somehow, fabricate up, a shroud that would encompass ALL the fins in that condenser? Does anyone think that, it would improve the efficiency and therefor, the cooling process of the R-134A in that system. And therefore, if your efficiency is improved, it should, I SAY SHOULD.....POSSIBLY.... get us colder air, emanating from the dash A/C ducts?????
