Just wondering.

unfortunately no....however, they do make electric turbochargers that will work just perfectly for that application. :lol: :smash:

Does this mean that it's getting a bit warm in sunny Florida?

How about a second compressor? You could have his and hers A/C settings. :jester

That wouldn't help anyway... It is a matched system. Evaporator, condenser compressor... Evaporator pressure is what creates the cooling along with the condensers ability to transfer the heat away. The compressor needs to be efficient though, but just bigger will gain nothing.

Have you ever tried it, or are you quoting a school book?
My AC guy says the compressor can be increased 1/2 ton for my house keeping the same air handler.
I would expect efficiency to drop, but i don't see why it won't work.(i'm not an expert on this, so i am open to actual experiences)

her? you have got to be kidding?? I would let her work on her tan.

I'd be worried about accomidating the boys, with that extra A/C :rant:

I've been told the long compressor on the older C3's is big enough to cool a 3 bedroom house as it is. The car system is limited by the size of the part in the system over which the air passes. Can't remember the correct term for it. Is it the evaporator?

No...but my Air Conditioning mechanic says he can install a Japanese Compressor on my 1981 using specifc fittings....He says they are more efficient than American Compressor made back in the 60/70/80's years.... :confused:
Anybody want to jump in on this.....have you seen this done before? :flag :seeya Cappy

A household A/C's are the bare the minimum so a larger compressor may reduce the running time of a compressor. Evaporator pressure/temperature has a definate relationship. Refrigerant won't get colder with a different compressor. More refrigerant circulating faster won't help if the evaporator and or condenser are too small to take advantage of the larger compressor..

LAvetteman

Correct, each air conditioning component is rated for a certain amount of BTU's. If either of the heat exchangers (condenser or evaporator)is not equal to or slightly more than the compressor, than the system will only handle the BTU's of the exchangers or possibly less. Increasing the bore of a compressor increases its BTU output, but if the exchangers can't handle it, its no good.

I have heard that a automotive system can be used to cool a house with some very creative "rigging". They say its been done by some financially challenged citizens. :)

The only way the outdoor unit can be increased 1/2 ton "effectively" is if the indoor "evaporator" is 1/2 ton larger allready. Which in many cases is, it is very common for a new indoor system to be intentionally 1/2 a ton larger than its outdoor, its a cheap and effective way to increase efficiency.

I strongly do not recommend sizing a compressor 1/2 ton larger than what the indoor is rated for, for many reasons.

I am no engineer, I speak with 2 years of training and 10 years in the field, thats right, I am a rookie. ;)

:confused: well i am all ears!
what terrible thing happens if the outside unit is increased 1/2 ton to now match the inside unit that was 1/2 ton oversize?
