Re: Two Condensers connected in series

This is a similar single turbo set up in the same exact car I own. He only has this single puller fan on the back of his radiator....no shroud at all. But all of his lower ram air is dedicated to flowing through the radiator while hes moving. No condenser in front of the radiator. This works on his ...

Re: Two Condensers connected in series

And there it is. 3 to 5 times a year, every year for the 12 years I have been on this board the same series of questions happens. 1)" My A/C sucks at ide / overheating at idle" 2) Questions about engines, parts, etc. - this can go on for pages. 3) "I got rid of the OEM fan(s) for spa...

Re: Two Condensers connected in series

By 1998 those cars already had Parallel Flow condensers. Your OEM unit is 25" x 15" . Just make sure it has enough airflow. Your car was an OEM electric fan vehicle, so make sure all of the seals, dams etc. are still in place for best airflow from the OEM fans. The pusher fans can be good...

Re: Two Condensers connected in series

Given the dribble of information on the vehicle, I can only assume it is a Gen 2 Firebird T/A. Those cars had large, one pass Tube & Fin condensers, which were not as efficient at transferring heat. A modern, dense fin parallel flow condenser has a big advantage. Consider that the entire conden...

Re: Two Condensers connected in series

As Bohica indicated the a CAC, a hefty charge air cooler, is pretty basic for your higher temp and pressure intake air if you expect that HP and any engine life. You said lower ram air is for the radiator which leaves upper ram air for CAC and then Radiator. But not enough height for condensers w/o...

Re: Two Condensers connected in series

Are there intercoolers in the cooling air path? Is there room for the condensers you plan to use in the front of the car? Or are they going someplace else? No, the two separate condensers will have permanent fans attached, with shrouds so all of the air being pulled through actually goes through th...

Re: Two Condensers connected in series

Actually, Chrysler used a series condenser in production. The 1996 Town & Country minivan added a second condenser in series when they put in rear A/C. 4" x 26" , and obviously intended for series cooling. P/N 4682591 Well, I'm glad to at least hear the series idea works.....Now I hav...

Re: Two Condensers connected in series

This is not about the surface area of the condensers, but of the refrigerant tube internal restriction, e. g., for a 3/8" tube fabbed condenser: entry could be 2 parallel 3/8" tubes throughout. The second condenser could be 2 parallel tubes entry and half way a transition to a single 3/8&...

Re: Two Condensers connected in series

I fabbed a dual condenser, supped up A/C'd Humvee. Condenser Basic Design Principals: A single condenser installation can be analyzed as 3 heat dissipators in series. 1) Initial heat disippator #1: Large internal flow flow cross sections for SENSIBLE heat transfer of superheated high vevocity gas o...
