I was not the first time confronted with the fact that people are quite sure that a conventional air conditioner takes to the streets of fresh air and ventilate the room. And when I tell people that this is not so, they are very surprised and asked, why, then, to go out of the pipe?
In fact, the coolant circulates through the copper pipe - freon. When it passes from liquid to gaseous state, it is cooled.
In the outdoor unit should the compressor that compresses the refrigerant and turns it into a liquid. By thin copper tube it flows into the indoor unit, there evaporates (the radiator cooling occurs) and in gaseous form by a thick tube goes back into the compressor of the external unit. chases room air fan through the radiator and cooled by the cold. In this case, it's the same air of the room and not the fresh air.
There are a few expensive models of air conditioners that have sucked the air from outside through a separate pipe by means of a separate fan. I, as the owner of such an air conditioner, with full responsibility saying that it is absolutely pointless garbage marketing: the fan hums loudly, thin tube, so the air is supplied ridiculously small. In reality this function does not seem to enjoy one.
Another myth: "When the end freon, air conditioner stops working, so it needs to be refilled." In fact, if the air conditioner is properly installed and all connections are completely sealed, Freon is not going anywhere - it circulates in a closed circuit.
More Myth: "When the air conditioner it is necessary to tightly close the windows, and then it will break." Not necessary! Conversely better to open the window or open up a window to the room of incoming fresh air. Yes, the air conditioning will consume more electricity, but the air in the room will be fresh.
More Myth: "To air conditioner rapidly cools, you need to put a minimum temperature." The cooling rate of all non-inverter air conditioners does not depend on the set temperature. Thermostat simply switches off the compressor when the temperature reaches a predetermined value.
"From the air conditioner all catch cold." This is not a myth but a delusion caused by improper use of the air conditioner. That the room was not comfortable should be placed 18, when the street +30. Put 3-4 degrees lower than on the street. Do not be afraid to put on the face of large numbers, such as +27. Believe me, when the street +31, +27 in the room is just right, and no one will catch a cold.
