Dual Aircon Connections of Condensers, tanong lang po..

[julian]

dudes,

nais ko lang i-confirm yung connection ng 2 condensers sa dual aircon. Tama po ba na naka-series yung 2 condensers at parallel
yung 2 evaporator sa dulo(diagram sa ibaba---illustration#1)?
Or, puwede bang series muna yung tig-isang condenser at evaporator, tapos i-parallel (see illustration#2)? Sana matulungan nyo ako bago i-fix ung dual aircon ng L3 ko.

Illustration#1:

hmmm...medyo nalito ako sa illustration. sa gen1 pajero ko may naka Y connector sa compressor. I have two condenser one infront of the radiator the other above the skid plate. I think naka series yun two condenser.

Malamang naka-series yung condensers dahil nililiquify yung refrigerant after compression and evaporation. Walang problemang naka-series dito dahil low pressure na sa condenser section.

From the series condensers, papunta na yung condensed refrigerant sa compressor. After compression (high side), patungo na yung refrigerant sa evaporators connected in parallel - dahil dapat parehong high pressure yung refrigerant patungo sa dalawang expansion valve-evaporator assembly.

medyo nalito din ako dun ah hehehe!

it does not matter if the condensers are in series or parallel, they will be at the same pressure naman kahit naka-parallel yan eh. if in series naman, once the refrigerant condenses then kahit na malayo pa tatakbuhin nya sa loob ng condenser ok lang yan. for me i prefer parallel since maximized ang heat exchanger area at a lower refrigerant flow rate/unit area of condenser. beter yan than series.

sa evaporator dapat naka-parallel yan, di pwede series.

buhayin ko lang ang thread na to ha.

do Dual Condensers need two Receiver Dryer and Expansion Valves seperately?

on dual condenser ac systems ,you don't need to install these extra parts .

check 1998 dodge grand caravan 3.8L , everything's the same w/ dual condensers.

[jick.cejoco]

siamese systems may or may not have two receiver dryers, they share the same compressor and yet have two separate evaporators. some have two condensers running in parallel each branch leading to one system or two evaporators sharing the same compressor and the same condenser. the front climate control is the main that turns on upon A/C request. the rear unit does not operate on its own and is a piggyback to the front unit. the rear unit is engaged or disengaged by a relay that contols the solenoid shut off valve and the evaporator fan unit. the condensers logically, have to be connected in parallel

[rion]

does this apply on dual with single dryer and expansion valve?

[jick.cejoco]

yes! but you have to install a solenoid valve on the secondary or auxilliary system and you use accumulator dryer for orifice systems

alright thanks

I have checked our ride. the 2nd aircon was add-on, not a factory installed one.

I think it works something like this: (if my pipe route readings are correct)



should this be just right? it doesn't have temp controls on the rear but my concern is, it is not as cold as it used to be, despite no leaks and freon seems enough.

it was cold back then, but this one part that always blows, I forgot what it was, it was years back. the aircon guy just condemn it, and since then it was not cold enough to satisfy on summers.

any ideas what on aircon part that blows aside from fuses? might give some clues.

what might have blown is the evaporator blower fuse. if it is not cooling sufficiently, maybe because the sensing bulb on your expansion valve is not on the superheated area of your evaporator. try relocating it a few inches away from the evaporator and closer to the expansion valve

[cocoy]

what does the system look like with dual compressors? would it be a totally indepentdent of each other?

alright thanks, I'll see if I can spot a better heated area and relocate it. regarding the blowing part. I'm certain it is not the fuse though. I can only guess it has got to do something with expansion valve release or somekind of pressure release condemnation.

would like to follow up if this diagram good enough? won't the dryer be inefficient with this system?

[jick.cejoco]

for passenger cars, pickup trucks and passenger vans up to 17 passenger club wagons, only one compressor is used. two would add to the weight of the vehicle versus one bigger compressor than usual. the two compressor systems are sometimes used for bigger buses or coaches, sometimes it would have an auxilliary engine just for the climate control so even if the main engine is off or not running, the auxilliary engine running, the airconditioning or climate control is working. similar to the auxilliary power unit (APU) of the aircraft, electrical power and airconditioning will be on regardless the main engines are running or not

thanks sir.. i was just wondering lang kasi yung mitsubishi Rosa bus ng school namin has dual aircon compressors.. i understand that it would be too much for cars or vans to have two compressors.. i was really just wondering lang how a dual aircon compressor would work..

he might have condemned the shut off solenoid to the rear unit. the drier should be sufficient. if the service tech vacuumed the system at around 29 inches of mercury for at least 20 minutes, reverified if the pressure rose and revacuumed, the system must be almost free of moisture if not at all.

I look at your diagram, mukhang mayroong mali sa connection ng condenser, the condenser should be connected in series.

[SIZE=4]GOOD DAY, actually this is out of topic maybe some gurus can give me some idea, i have a advie and planning to put an additional condeser sa ilalim ng driver with a aux fan, d kaya makabigat ito sa makina or lumakas o tumakaw sa diesel with this new upgrades, gusto ko kasi super lamig ang aircon ko thanks.[/SIZE]

you're correct den1106 .kaya ako nagbigay ng example (1998 dodge grand caravan 3.8L manufacturers standard plumbing ng dual condenser)

pag may pwesto sa front ,the best yun .don't forget na connected in series yung condensers as den1106 stated.
