The principle of central air conditioning refrigeration

The principle of central air conditioning refrigeration The liquid Freon enters the evaporator through the capillary. The space suddenly increases and the pressure decreases. The liquid Freon will vaporize and absorb a lot of heat. The evaporator will become cold. The indoor unit fan will remove the indoor air from the evaporator. Blow through, so the cold air blows out from the indoor unit. Let's take a look at the cooling principle of the central air conditioner with the editor for your reference<img src="{{media url=&quot;magefan_blog/The_principle_of_central_air_conditioning_refrigeration.jpg&quot;}}" alt="" />
