Re: Tube & Fin Condenser on Roof?

Davo, Wow! It matched the record of 50.7 C (123.3 F) in Onslow today. CAT operating in the open pit Ausse mines get even hotter radiation and conduction heat loads. Testing AC in Death Valley, CA at 120 F and pulling a trailer up Baker Grade is our ultimate AC & engine cooling design validation....

G'day Mate KF Head with 1 1/16" threaded #12 horizontal suction port. not HF ??? Latest Sanden DEC SP10 PAG 46 is close to Denso PAG but Sanden SEC SP20 is NG. If rooftop condenser doesn't dissipate heat that is absorbed by evap/comp, a series front of radiator secondary final condenser/subcool...

Re: Tube & Fin Condenser on Roof?

G'day Mate, Oil quantity and liquid refrigerant migration: After a cold night lowers the low mounted compressor housing temp the high mounted condenser warms up in the morning sun just like an agricultural tractor. Result is that refrigerant migrates to the coldest part of the AC system (without oil...

Re: Tube & Fin Condenser on Roof?

G'day Mate at the billabong, My 2 cents: 1) The condenser BTU rejection bogey is evaporator BTU absorption plus compressor drive input energy (horsepower in BTU). Approx Condenser BTU = 22,220 (rated) + 7,777 (30% to 35% of evap absorption or use compressor curves at evap rating conditions) = roughl...

Re: 2016 Ram line sizing issues (#4 size?)

2 cents: First prize for a non grill mount condenser would be a roof mount that is designed to get a boost from ram air. Avoid turbo & engine cooling air exhaust under vehicle into condenser. I've mounted condenser on back of cab on class 6 trucks and under trunk on Model A but temp in Phoenix i...

Re: Delenair system on vintage Jaguar

I have had 100% success on Class 8 trucks keeping the R-12 non barrier hoses. Recommend you eliminate the Delenair TXV inlet screen.
