how does an A.C. cools the air?

Answer 1

Outside the house you have a condenser unit with a compressor. The compressor compresses freon gas and that makes it hot. The condensor then removes the heat and turns the freon into liquid. That is why the outside unit blows out hot air. The liquid freon then goes to the evaporator inside the house. In the evaporator, there is a thing called the thermostatic expansion valve or some capillary tubes (very small). The liquid freon discharges through the TEV or capillary tubes and when it does, it expands in the presence of the suction from the compressor to form a gas. As it forms a gas it draws heat from its surroundings to do that. That is why the evaporator gets cold. The cold freon gas is then sucked through the coils in the evaporator where it draws heat from the air coming across them back into the compressor, where the compressor compresses the cold gas and it gets hot again, and the cycle repeats itself over and over as the unit runs!

Answer 2

The basic answer is freon is pushed thru a condensing unit and thru an air exchanging coil. As Air goes over the cold coils the warm air is cooled and then forced into your home (or refrig.)

Answer 3

By removing heat from it.
"Cold" is just the absence of heat. The air conditioner uses chemicals inside a sealed system that have unique properties -- they give off heat when they are compressed, and absorb heat when they are expanded. The AC system alternately compresses these chemicals inside it's system (which makes them give up their heat), where the heat energy is released outside your home/office. Then the coolant is de-compressed (allowed to expand), cooling it, and it's passed through a grid over which air that is to be cooled is blown by a fan. The expanded coolant absorbs heat from the air, then it's sent back outside and compressed to give up the heat it absorbed. It does this over and over again.

Answer 4

Someone told me that it sucks a lot of the hot air out of the room but it doesn't explain the cool air that pushes out, does it?

Answer 5

it works slightly similiar to refrigerator.it has thermostat which cools the air and circulate hot and cold air whe the desired temp.is reached it stops and then again starts when temp. drops. it is not like typical cooler it works without water.

Answer 6

air is passed through the codenser unit through the condenser coil which cools the air.

Answer 7

air runs through freezing coils and that cools down the temperature.

I agreed with Mr Welltravell
