First post here. Seems like a smart group of guys around that can maybe help with this question.
We build off-road machines with the engines mounted at the rear, maybe 20' away from the cab, and use an engine driven a/c compressor. This approach has worked great for many years, just not so good in the mid-east with desert ambients of 120+F. So, some of our competitors claim they have improved performance by hydraulically driving the compressor and mounting it closer to the cab and minimizing the Freon hose length. My contention is that there should not be that much difference in performance assuming the hose ID's were properly chosen, and that the compressor speed remains the same, evaporators and condensers are the same. I would sincerely appreciate any insights all of you might have!
