Re: 1961 cadillac conversion

SD5H11 LOL You may need to modify OEM blower inlet in AC mode for 100% recirculating air. At 95F/50%RH most OEMs will meet or beat 45F discharge air with 100% recir air but the boggy is only 55F with full outside air. I usually install a shut off water heater valve for summer cooling on vintage OEM ...

Re: 1961 cadillac conversion

Outside the box: 2xo is 75% correct that compressor swept volume displacement can solve your low refrigerant mass flow problem. Suction gas flow restriction is the rest of the story. Relatively small suction hose I.D., bends and choke diameters inside fittings at the compressor should also be includ...

Re: No cool at idle and smoke

PRV rarely resets to original spec and should be replaced due to aluminum fines stuck in the pop off seat.

Re: No cool at idle and smoke

Probably oil and refrigerant release onto exhaust manifold from PRV pressure relief valva due to overcharge of oil and/or refrigerant.

Re: 1987/1993/1996 Bronco AC upgrade...

Highly likely they're mufflers. I have one on my car's suction line and it's supposed to keep the reed valve noise from reaching the evaporator. Fails miserably, in my case. Here's a pic. SD7 had discharge reed noise due to oil stiction with flutter caused by BOURNELLI effect (lowering pressure at ...

Re: Evaporator fin density and differing TXV adjustments

Some of Your techanical comments are basically applicable to variable displacement compressor optimization and have little to do with fixed displacement comps or evaporator capacity. Evaporator fin density is a function of evaporator air velocity, suck verses blow through evap, , heat transfer betwe...
