Does an Air Conditioner works better in Humid Climates than the Dry Climates?

Question

Which would cool faster using an Air Condtioner.
A Room in dry climate at 100 deg F or same Room in humid climate at 100 deg F.
Also, in which case the AC will have to work more.

Answer 1

Depends on what you mean by work better. If you mean will it cool to a lower temperature, no it takes substantial energy to condense water from vapor. If you mean will it make you feel more comfortable, yes , by removing high humidity, you will feel more comfortable.

Answer 2

Better in dry Climates.
AC Unit cooled by outside temperature 100F , the same performance no matter Humid/Dry Climates - because the outdoor fins is dry/no evaporative cooling on fins.
The problem is when indoor unit works in Humid Climates, they work more hours (less idle condition) to remove humidity (Latent Heat).

Answer 3

In dry climates they use evaporative cooling. Air is drawn through a dampened foam or shredded aspen wood pad. As the water evaporates, the air is cooled and forced into the building.

In humid climes, referigerated air works best as the relative humidity prevents the evaporative coolers from working.

Reefed air also uses the phenomenon of evaporation, but in a closed circuit using freon, or high pressure alcohol.

In coiled pipes, the freon is cooled into a liquid state by air which is forced over the tubes. This process occurs in a unti mounted outside the building and the air used is discharged outside. The cold freon liquid is then allowed to expand and is heated by forcing air across another set of coiled tubes usually inside the building. This air is forced through ducts in the building as air conditioning. The loop starts all over again. This is over simplified, but I only have a few minutes.

Reefed air will work in humid or dry climates, but evaporative coolers are much cheaper to operate and buy in dry climates that reefers are rarely installed in homes, but are commonly used in larger applications: stores, hospitals, etc.

Answer 4

Yes, the primary function of an air conditioner is to remove the humidity from the air.

Answer 5

Puropose of airconditioners is to give a feeling of comfort which is achieved by maintaining temp. /RH of conditioned space at 22 deg C/ 60% RH . .
In case air is more humid , moisture from air is to be removed by cooling to its saturation temperature by air conditioner and extract latent heat of water .
. If air is more dry, moisture is to be added by spraying water into it which spontaneously cools air as well helping conditioner .
So, dry air is more conveniently conditioned by conditioner of same capacity than wet air ..

Answer 6

of course, AC works same but effect ( room cooling ) is better in case of 100F and dry condition. Ac has certain capacity to remove heat load. there are two types of heat load...sensible and latent. In dry condition only sensible load prevails,in humid condition sensible as well as laten load prevails. hence AC has to remove both in humid condition hence final cool temp is less.
AC works better in dry condition . Don't see qty of water condense from AC.

Answer 7

I believe it does, because dehumidifying is what they do well, and for overall comfort, dryer means a lot.
