Question:

Air conditioning blows out hot air and cold air is how come?

Air conditioning blows out hot air and cold air is how come?

Answer:

Generally the indoor heating or cooling process after the wind circulation enter indoor, if it is fresh air of air conditioning, fresh air into the room, there will be department would, of course, also have a department to indoor and outdoor wind ruled out
Yes; Refrigeration, sheer, refrigerant cycle from air conditioning; Heating and part of the air conditioner with electric heating function. (compressor gas freon compression for high temperature and high pressure liquid freon, and then sent to the condenser (seg) become a room temperature high pressure liquid freon after cooling, so the blowing out hot air. Outdoor liquid freon via capillary, into the evaporator (indoor machine), space suddenly increases, pressure decreases, and the liquid freon will vaporize, become a gas at low temperature of freon, to absorb a lot of heat, the evaporator will become cold, indoor machine of the fan will indoor air blows from the evaporator, so the indoor machine blowing out cold air, and water vapor in the air is cooled after the evaporator can condenses into water droplets, along the conduit flow out, this is the reason why air conditioning will be out of the water. Then the gas freon to go back to the compressor compression, continue to cycle. Heating when there is a call of four-way valve parts, freon in when the direction of flow of condenser and evaporator refrigeration instead, so the heating time is the cold wind blowing, outdoor indoor machine blowing hot air. It is to use the liquefied learned in junior middle school physics (changed from gas to liquid) to emit heat and evaporation from liquid to a gas () to the principle of absorbing heat.)
Simply speaking, the outside air conditioning heat and cold is machine compressor work, make the inside of the pipe refrigerant cycle; Through the four-way valve switch; Make the machine evaporator heat and cold; Through the fan rotation, make the air through the evaporator, the heat and air conditioning to; Is such a blow out hot and cold wind;
Compressor refrigerants is high temperature and high pressure gas, by this time directly to the indoor machine, is the heating; To seg will heat dispersion, and then through the throttling device is lower than liquid at room temperature, through the indoor machine evaporate, refrigerant take indoor quantity of heat, is cooling. Heating can imagine into hot water, cooling can imagine into alcohol coating on the skin...
Home air conditioning is to use cold media in the heat exchanger makes its continuous evaporation, indoor air through the heat exchanger, the refrigeration effect. Heating principle is to use parts of a "four-way valve" to make the opposite direction of refrigerant flow, will be completed the hot suction indoor to outdoor heating function.
