A Little While back I added A/C to my 1097R1
Red Dot Evaporator, Sanden 508 Compressor with 24VDC Clutch, BlackDog Customs Compressor Bracket, Red Dot 5 groove water pump pulley. bunch of hose and fittings and a parallel flow condenser from Coldmaster, and a simple wiring harness. works quite well.
Ended up with the condenser on the cooling stack dual fans, Had a minor issue with the manifold gages I used for automotive the low side valve stopped working. had to use a consumer trigger hose. Meh it worked. Designed and 3D printed from ASA plastic some Square to round duct transitions. Fabricated the Evaporator brackets from 3" x .125 aluminum angle (6063) a bit ham handed but they work. Control from Coldmaster. has 4 speed fan and rotary temp control there is a thermistor in the evaporator. I put mesh wire wrap around the main forward to rear trunk, this is all 24VDC so the main power comes right off the batteries just like the Red Dot setup. the Evaporator arrived brand new in a Red Dot Box Damaged... the plastic duct around the dual squirrel cage fans was broken so when first powered up the fans were rubbing and dragging so bad it started blowing fuses and burned out the speed controller. I initially repaired with nylon Zip Ties, Coldmaster shipped a new same manufacturer fan assembly immediately. While it is still uninsulated the system pours 41 degree air on my head. and reduces 105 degree air to 80 degrees and lower ambients to much less.
A Bit of Simplification.
the smallest hose is the high pressure "Liquid" line, the Largest is the "Vapor" line or lowest pressure, the MIDDLE size hose is the high side of the compressor. smallest is #6 Largest here is #10 and the "Middle" is #8 so if we start at the Compressor Number 8 goes to the TOP of the Condenser, #6 comes from the bottom of the condenser, that goes all the way back to the Dryer, which is the canister shaped item. from THAT to the EVAPORATOR in is also #6 then #10 is the return that goes back to the compressor. you can see in the thermal pics attached that the dryer and high side lines are quite hot. the lines all run UNDER the Hump Floor over the transmission and exhaust I WANTED to use a bulkhead connector in the floor there and had it but the supplied fittings for the dryer were Straight not right angle so for my mounting solution they would not work. Most mount the dryer on the fender liner on the passenger side. it would not fit there for me. so it is alongside the evaporator. as shown. the Red Dot instructions show the Dryer mounted outside the cab on the back wall. and the condenser is also on the back wall or the roof. I chose not to do any roof penetrations on the Helmet top. the Condensate drains go through the floor behind the evap. I tied them to a stainless Tee fitting there.
