Which A/C setting can help save fuel?

[c",)tots]

guys, which aircon setting can help save fuel: low thermostat setting+high fan speed, or high thermostat setting+low fan speed?
TIA.

i've found that mid-thermostat plus low fan speed cools the cabin faster under normal situations. thats probably because the air from the fan has more time to pass over the cooling fins of the evaporator, instead of just blasting high speed air.

here in the phils i run my a/c at mid-cool, fan setting 1 or 2. oks naman. paired with super black tints... ok na ok. the compressor cycles at half the number of times than say, at high cool.

gained fuel mileage is small, but over long distances it can pile up.

Don't overlook the fact that the A/C's job is to provide comfort to you AND your passengers. In other words, saving a few drops of fuel while the passengers at the back seat are sweating isn't right. :D There's no one fixed thermostat or fan setting that will be applicable to all situations. Adjust them accordingly so that all passengers are comfortable.

Keep in mind that whenever you or your passengers feel cold, you're using more gasoline than necessary. Adjust accordingly and for every situation.

In most cars, idle fuel consumption increases by about 50% whenever the A/C compressor is running. In my video below, with the A/C off the engine consumes about 0.88 liters per hour (LPH). When the A/C kicks in, the number jumps to 1.32 LPH.

What kind of van do you drive sir Aga?...for me curtains are a thing of the past (hindi na bagay), if I were you I'd just pick a suitable tint that would make me feel comfortable while inside the van.

3m or solarguard (not sunguard!) tint na lang...

superblack all around and medium or light black sa front is nice. ayoko kasi ng masyado maliwanag sa loob, masakit sa mata. my experience, walang binatbat yung araw at init.

To answer your question, for cars with thermostat controls only for cooling (w/o heater): The low thermostat+high fan speed setting (mid setting would usually be sufficient) would save fuel vs high thermostat+ low fan speed setting.

But for some cars with thermostat knobs, which controls both cooling and heating settings (which mixes cool and hot air at low thermostat settings), not sure but would expect no more fuel savings at low thermostat settings.

For a few minutes or hours lang of travel titipirin pa natin? My take on this are: kung nabilad? few minutes at no. 2 fan then return it to no. 1 na with thermostat set to desired coolness (1/2 to ¾ max) and kung galing sa garahe, night time or walang araw naman no. 1 fan lang.

Kasi the lower the fan speed the lesser it sucks air (dust and dirt) that passes thru our evaporator so tipid rin sa cleaning

my maximum setting during summer is that the termostat is in 1/2, blowr is at 3, pag may sakay. pag ako lang mag-isa, lower is at #2 initially, tapos binababaan ko to #1.

pag cold months, my thermo is at 10 o'clock, fan is #1. minsan pag sobrang lamig, pinapatay ko na.

i find these settings most efficient for me. of course, depende yan sa condition ng aircon mo.

* mr. aga.... i dont know if u find what ur suggesting for ur van is cool...

but my perception is they ...L...A...M...E i think vehicles that has pics/posters on windows are... trucks... company vans... PUJ so i suggest no no for this...

about the black sticker with holes would be best low budget but is good...

curtains??? hhhmmm maybe if u drive a hiace van from subic or delica some actually have em' but if ur driving a decent van tint would be the best.... 3M -sakto lang sa budget- yung solar guard and v-guard are very expensive >.<

thanks co nix

[woohoo]

Huwag nga mag-curtains. Lalo na kung station wagon pa ang lalagyan ng curtains! :hysterical:

Baka isipin ng mga tao, ito ang passenger mo:

to all. thanks sa lahat ng posts niyo. helped me realize a thing or two. A/C is there for comfort, so if i want a comfortable ride, kelangan ko i-compromise fuel ko. so far, nag aadjust ako ng A/C setting depende sa situation, ex: morning, noon, galing sa bilad, sa parking, evening, etc. havent tried full thermostat nor full fan speed. after your posts, am between 1/4 ~ 1/2 ng thermostat, and between 1~2 na fan speed. sa experience ko big help din na OK tint mo, right now 3M light black ako sa front then 3M medium black sa sides/rear.

* sir aga. go for the tint, either 3M or Solargard, i think any of the two works best sa present needs mo.

ur welcome tots & thanks wohoo


co nixz kapit bahay lang kita tuktukan ako hahahaha lapit sa munisipyosan makikita pics up mo?

agree..

for cars with "climate control" that only mix hot and cold air to adjust cabin temp, its better to set your thermostat to the coldest.. just manually turn off your A/C when you feel cold and turn on as necessary.. this is the best way rather than setting it to 3/4 or whatever setting near the hot zone..

btw, modern engines are more efficient and the A/C load doesn't much affect fuel consumption.. there is already a study conducted regarding A/C turn on and off and the fuel consumption is just the same.. also make sure your A/C is functioning properly to avoid the engine and the compressor working for nothing...

what really affects your fuel consumption is your TIRE PRESSURE and UNNECESSARY WEIGHT you carry at your trunk or too much accessories, wheel alignment and brake problems.

i adjust the thermostat and fan speed to the setting which i will be comfortable. dati akala ko rin you can save fuel by scrimping on airconditioning. yun pala yung car namin hindi ganun. it only mixes the hot and cold air.
