Re: condinser too hot

20 psi suction proves that discharge valve and scroll tangential gas bypass are ok. Scroll mounted thermal protection switch (TPS) may disengage clutch at low suction/high discharge or air in system Excessive oil just raises louver temp with scroll application Normal scroll wear turns oil gray but d...

Re: AC overhaul pressure problem

Delphi tech The scroll compressor can run liquid slugs all day because of the compliant eccentric with swing link that allows the scrolls to separate which allows tangential leakage with abnormal liquid. Tested 4 times at Lockport with TRS120 scroll on LT and monster condenser which provided 29,000 ...

Re: Liquid line inside suction line?

The suction line heat exchange increases the overall icentropic system efficiency which results in slightly less horsepower per ton of cooling and can reduce liquid refrigerant below ambient for colder louvers Worked on a Rolls Royce with a larger SLHX made by ARA. Rolls was a salesman and Royce a e...

Re: System design with GMA6 Compressor

G'day Mate, FYI: OEM A/C engineers measure "engagement bump" on a dyno with a dial indicator touching the underside of the front bumper. The scroll and external control compressors are first prize for this fully objective evaluation. Vintage Air book "How to Air condition your Hot Rod...

Re: System design with GMA6 Compressor

G'day mate, Now i get it! You'r trying to avoid a sunburn right arm wilst remaining a purist. Engagement torque = 50% pumping torque + 50% (or more for iron components) torque to over come rotary moment of inertia. Engagement torque shock causes deceleration which is barely noticable or measurable w...

Re: System design with GMA6 Compressor

3X Problems with A6 are weight of monster iron & steel 12.6 in3, high parasitic torque draw, heavy mounts causing undesirable coil spring height reduction on mounting side, borderline shaft seal with some refrigerant /lube combos, excessive pressure due to limited condenser real estate, front bu...

Re: Need AC advice for 2000 Silverado

By 1990 most compressors except 2 cylinder York recip and A6 had dual lip seals (one for vacuum and one for positive pressure) lip seals should not seep oil because oil causes clutch slip modern lip seals have a spiral groove to return tiney amount of seeped oil back into compressor electronic leak ...

Re: 2004 Stratus

My memory is Stratus has a txv with scroll compressor which has a temperature protection switch (TPS) less than 1 pound refrigerant charge is dubious txv systems are typically slow to equalize 1)TPS will cycle compressor clutch with low charge and high side will be abnormally low while low side will...
