dual aircon controls sa SUVs and AUVs and Vans

[Dianne]

Do you turn off your aircon blower fans sa likod kung ikaw lang ang sakay? Somebody told me kasi na hindi advisable patayin while the front
is running to prevent coolant clogging sa coil. Better to run daw at low
fan (level 1) rather than totally off. :?

[mackieboy]

yup yup! <-- mali ako ng intindi. Always ON yung sakin.

yun din advice sakin nung PMS na aircon..
dapat palagi din daw malinis yung front passenger side (adv 2002 model) kasi dun nangagaling yung air papunta sa Aircon (something like that.. )

[gambit5]

Bago to ah!!! di ko alam eto.... lagi ko pa naman pinapower off yung aircon/blower ko sa likuran....tsk ... tsk.. tsk...

sir Macky, ano yung malinis na front passenger side ?duon ba sa may radiator ?

[OTEP]

Dianne,

On the Pajero, I turn it off kasi maginaw. Minsan hindi na nga ako talaga gumagamit ng aircon. You don't really have to run it all the time. Kahit once a week lang as stated in the owner's manual. Refridgerant yata yung nasa loob niya, hindi coolant (correct me na lang guys).

mackieboy,

Yung a/c kumukuha ng hangin doon sa likod ng glovebox where the blower and the evaporator are situated. Pwede rin siya mag-draw ng air from the base of the windshield (sa labas) if you turn off or move the recirculate lever/button (depending on vehicle). Yung rear a/c kumukha ng hangin doon sa small grilles above the front passengers' heads on the Adventure. Sa Pajero, nakatago sa likod yung intake ng rear a/c and is protected by a steel and plastic mesh filter.

ung saken naman lagi nka 1 kpag nka on ung a/c para hindi lugi pg ngpalinis:mrgreen:
revo nga pla gmit ko...

If your rear aircon is equipped with a shut-off valve, ok lang i-off. The valve gets the power from the switch. Pag off ang switch, for the rear, shut off a refrigerant papunta ng rear aircon. Yon sa akin walang valve kaya I keep it sa 1 setting.

[ace]

Ako pag mainit, i turn the rear aircon on kahit mag isa lang ako. Otherwise lagi syang off.

By the way, may benefits ba kung naka off yung rear aircon? I mean will it help with regards to fuel consumption, hatak etc.?

[jay crew]

yung samin naka low lang lagi di ko na tinatangal,ok lang ba yun yung ride 2001 paj,basta yung push botton yun di ko na inooff, di kaya masira yun?

Very little with regards to fuel consumption. If there's any I think it's on the electrical load. :wink:

[ace]

thanks for the reply alfrasay.

So it will be more prudent to turn the rear aircon on and have the thermostat on a lower setting rather than turining the rear aircon off and have the thermostat on a higher setting :?:

My apologies kung OT na ha :wink:

[mdpo]

ask ko lang... yung trooper ba may shutoff valve?

thanks

[OTEP]

mdpo,

Most probably meron. Halos lahat ng OEM systems ay meron, eh.

[Dianne]

Maybe the shut-off valves are only present sa SUVs and big Vans. I am not sure if
the AUVs have them. Mine don't.

In terms of fuel consumption, minimal nga lang daw... kasi the thermostat naman for
the aircon (I'm speaking of my adventure nga pala) is at the front, so the turning on
and off of the compressor is govern by the front temp.

Recommended daw kasi ng aircon casa to have the back blower open even at low setting to prevent coolant (or refrigerant) clogging.

[mdpo]

meron naman pala... hmm ask ko nalang panu malalaman? e.g. like pag binuksan ang aircon sa likod maski patay sa unahan malamig????

Don't know if its because of the cold weather but maski naka off ang unahan ko malamig parin yung hangin sa likod ng trooper ko. unlike sa MPV... pag patay ang harap.. hangin lang yung sa likod.

thanks

Mas maganda kung naka on yung blower sa likod. Yung ibang A/C systems kasi walang shutoff valve sa rear unit kaya ang tendency, kahit naka off ang blower sa likod, continous parin yung flow ng freon sa rear evaporator and will probably cause it to clog with ice kasi walang dumadaan na hangin.
Unlike sa L300VV, meron syang shutoff valve kaya kahit patay yung blower sa likod, ok lang kasi narerestrict ng valve yung freon flow sa rear A/C unit.
Ganyan ang naging problema namin dun sa MB100 ng kaibigan ko, hindi nila binubuksan yung rear A/C blower kas inapakalamig daw, ayun pag gusto na nila ulit buksan, ang tagal bago lumamig kasi nag accumulate na yung yelo sa rear evaporator.

ito po pala yung ibig sabihin nung mitsu aircon nung nagpa-PMS ako ng aircon ng adventure.

kaya i always turn it on.

(i edited my previous post na) :lol:

Up ko lang kasi gusto kong itanong kung paano malalaman kung may shutoff valve yung rear aircon unit, medyo naguguluhan pa rin ako. Yung mga bagong labas na van ngayon, may shutoff valve na kaya sila lahat? Alam kaya nila sa casa ito kung itanong ko sa kanila?

Madalas kasi pinapatay ng kids ko yung blower sa likod pag nakaandar na kami ng ilang minuto dahil sobrang lamig ng aircon ng Starex, nasa gitna na nga yung setting ng thermostat nun.

[OTEP]

Ok lang naman patayin nila yun. During the whole winter season in Korea, hindi naman ginagamit rear a/c. They use the rear heater instead which is a separate unit mounted on the interior side wall.

[mikey177]

But Otep, we don't live in Korea (joke)

[OTEP]

Oo nga, Korea-novela lang meron. hehehe.

I let my passengers turn off the rear a/c when they feel cold. Parang wala naman bad effects.
