How The Air Conditioner Works

Jul 25, 2021

Air conditioners are divided into single-cold air conditioners and dual-purpose air conditioners. The working principle is the same. The refrigerant used in most air conditioners before is Freon. The characteristic of Freon is that when it changes from a gaseous state to a liquid state, it releases a large amount of heat. When it changes from liquid to gas, it will absorb a lot of heat. (That is, the air conditioner is designed according to this principle.

The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a normal temperature and high-pressure liquid refrigerant, so the outdoor unit blows out hot air.

Then it goes to the capillary tube and enters the evaporator (indoor unit). After the refrigerant reaches the evaporator from the capillary tube, the space suddenly increases and the pressure decreases. The liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thereby absorbing a large amount of Heat, the evaporator will become cold, the fan of the indoor unit blows the indoor air through the evaporator, so the indoor unit blows out cold wind; the water vapor in the air will condense into water droplets when it meets the cold evaporator , Flow out along the water pipe, which is why the air conditioner will emit water.

When heating, there is a component called a four-way valve, which makes the refrigerant flow in the condenser and evaporator opposite to that of cooling. Therefore, when heating, the outdoor unit blows cold air, and the indoor unit blows hot air.

In fact, it is the principle of discharging heat during liquefaction (changing from gas to liquid) and absorbing heat during vaporization (changing from liquid to gas) that was learned in junior high school physics.

Working principle of environmentally friendly air conditioner:

The water in the water tank is continuously pumped out with a circulating water pump, and sprayed evenly on the evaporation filter layer through the water distribution system. The outdoor hot air enters the evaporation cooling medium, and the evaporation cooling medium CELdek (the honeycomb filter layer of special material, To make the cooling effect more ideal, the Swedish high-tech patented product) fully exchanges heat with the water. The cool and clean air cooled by the water evaporation and heat absorption is pressurized into the room by a low-noise fan, so that the hot air in the room is exhausted. Go outside, so as to achieve the purpose of indoor cooling.
