Re: Mini compressor/less CID output?

I'd modify your Impala OEM AC to only use recirculated air (not 20% OSA) and a additional 100% hot heater water shut off in Max AC mode. Then your OEM AC would work as good as a Vintage Air HVAC replacement. Additional Dynamat floor, under hood evaporator housing and firewall insulation helps. Vinta...

Re: AC compressor leaking - Can I patch it?

As Band of Brothers we sometimes offer to complete a thought (scroll shedding). Scroll compressors use one hard anodized scroll and one soft aluminum scroll. A scroll system with several hundred hours will have aluminum gray oil due to the soft scroll conforming to the shape of the hard anodized scr...

Re: Fresh air infiltration while in Recirculate Mode

My city water department tests for leaks in the city sewer system with oil mist which has no smell. Japaneese cars first designed HVAC with 100% recirculation instead of the 15% to 25% outside air (OSA) blend used by the big 3 in the MAX mode. My Ford uses some OSA to prevent gas fumes and has a rec...

Re: new member and have a non typical application

Wanted to attend SEMA. The clutchless compressors usually have a weight advantage because the field coil winding and armature plate are eliminated. The system must be optimized to prevent compressor failure at low displacement OCR year round operation. I received a month of training on VDC and Clutc...

Re: new member and have a non typical application

bohica, iron sharpens iron. We shared some really good AC engineering together over the years! Hope you get to Texas or I visit Las Vegas some sweet day.That was some important training for me for book authorship since I failed English. You gotta love the challenge of solving AC problems. danev2 Sur...

Re: new member and have a non typical application

bohica 2xo Roots with separator and Wankel have disappeared along with vane rotary. Speed pads are new to me. Lots of R500 in TX tractors. Smell during service is obvious. Agree that separator could be made (of aluminum) with little weight penalty smaller than a aluminum accumulator. I have a compac...

Re: 2006 Civic DX AC not working

The extra 3d wire on Hondas is a signal for the computer to know when the clutch is engaged.

Re: new member and have a non typical application

I like oil separator also because it increases reliability and improved efficiency, but it comes with a weight penalty. If MD uses a 28 Volt DC motor for compressor drive then my design (used for military vehicles) with a 85.7 cc swept volume, modified scroll clutch assembly, serpentine belt drive c...

Re: new member and have a non typical application

Rotary wing AC ain't easy! Challenge for copters is weight control of AC so fuel load can be optimized. Highest priority is cooling of electronics. Next priority is pilot and last is Passenger comfort as the lowest priority. Parasitic energy draw of AC must be considered and will comprimise passange...
