What is the concept behind air conditioning? Where does it get all that cold air from?

Answer 1

It doesn't get the cold air from anywhere. Instead, an air conditioner removes the hot air from your house...leaving the cold air inside to re-circulate with the blower or fan. The concept is related to thermodynamics. Essentially, the refrigerant (freon, typically) is stored under pressure in the exterior portion of your unit. When the pressure in the vessel containing the refrigerant increases...the refrigerant absorbs heat from the inside portion of your unit...and vents this heat to the outside. Essentially, this removes hot air from the room...leaving only the cool air to re-circulate on the inside.

Answer 2

An air conditioner is essentially a heat pump|

It pumps heat from the inside of the house to the outside, so the result is cold on the inside|

If you go to the outside part of the air-conditioner, you will always notice that it is blowing hot air while it is working|That is simply the heat that it is moving from inside the house to leave only the cold as the cold is simply the heat that has been removed| Cold is not a thing in itself, but is simply the absence of heat|

Answer 3

I,ll try to explain the simple way. The ac is a sealed sytem consisting of a evapraotor core, a condensor and a compressor.This system contains a refrigirant .There is different ones.In vehicle it,s called R 134.This refrigrant runs underlow pressure when it enters the evap core inside the car and absobs the heat in the air from the core the sends it out to be cooled down..thru the condensor .I believe they call this process Laten heat evporation .It,s the Refrigirant that cause the cold .It works like a refigarator

Answer 4

Basically it is a HEAT - EXCHANGER
Freon (liquid that boils at low temperatures) is circulated through the system by a compressor. The compressor changes a low pressure vapor into a high pressure vapor. The vapor goes into condenser (radiator in very front of car) where the high pressure vapor is condensed into a high pressure liquid. The liquid moves toward the cabin (inside of car) where it has to squirt through a very small hole called an orifice. This is where the high pressure liquid turns into a low pressure vapor. The vapor acts like a sponge and removes the hot air flowing across the evaporator core (baby radiator inside car). Heat moves easier to a cooler surface and the result you feel is the cool air coming into the car.

Answer 5

Air conditioning work by moving heat. It moves the heat from inside the car or house and place it outside. The lack of heat is coolness.

Answer 6

Its just like ur refrigerator ur car's Air conditioner has freon which is a gas that reduces the temperature of air then a fan pushes the air through ur airvents thus making you stop sweating on hot days :-)

Answer 7

AC dosent actually make cold air.. what it really does is remove heat from air and pump that heat outside through evaporator and condensor coils and referigerant...

Answer 8

By pressurizing and de-pressurizing refrigerant we can make it absorb unwanted heat. By running a fan across the system we can displace the heat to a place outside of our car, room, house, etc.
