What are the reasons for the Magotan's air conditioning not cooling?

[DeMiranda]

There may be the following reasons for the Magotan's air conditioning not cooling: 1. Refrigerant issues: The car's air conditioning system consists of multiple metal pipes with small gaps between them, leading to minor refrigerant leaks in the system. Additionally, the dryer in the car's air conditioning system absorbs moisture and retains some refrigerant, so when the refrigerant level decreases to a certain extent, the cooling capacity of the car's air conditioning will be reduced. In some models with dual-zone air conditioning, insufficient cooling may result in hot air blowing from the vents. 2. Excessive dirt in the compressor oil: This can clog the filter screen of the filter, leading to poor cooling performance, increased resistance, and reduced refrigerant flow to the expansion valve, causing the car's air conditioning to stop cooling. Sometimes, if air enters the car's air conditioning system, it can cause excessive pressure in the refrigerant pipes, leading to poor refrigerant circulation and insufficient cooling. 3. Problems with the dryer: Its main function is to absorb moisture from the refrigerant and prevent excessive moisture from reducing the cooling capacity. When the desiccant in the dryer becomes saturated, it can no longer filter out moisture. When the refrigerant passes through the expansion valve's throttle orifice, due to the drop in pressure and temperature, the water in the refrigerant can freeze in the small orifice, causing poor refrigerant flow, increased resistance, or complete blockage.
