How does air conditioning evaporator works?
Air conditioning evaporator works by absorb heat from the area (medium) that need to be cooled. It does that by maintaining the evaporator coil at low temperature and pressure than the surrounding air. Since, the AC evaporator coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be lower than the air. The expansion device provides a pressure reduces between the high side and the low side of the system, the saturation temperature of the refrigerant entering the air conditioning evaporator is lower than the medium to be cooled. One of the characteristic of a refrigerant is that as the pressure is reduced the boiling point is also reduced. Therefore, as the pressure is reduced through the expansion device so is the point at which it will boil and become a vapor. As the warm air from the space passes over the evaporator coil, it gives up its heat to the lower temperature liquid/vapor mixture passing through the evaporator. As the liquid ref
