What are the consequences of internal blockage in a car air conditioning condenser?

[Zelda]

Internal blockage in a car air conditioning condenser can significantly reduce the cooling effect. When a layer of dirt adheres to the condenser, the condensation efficiency deteriorates. Here is relevant information: 1. Blockage at the outlet: If the refrigerant outlet of the condenser is blocked, the air conditioning compressor may operate intermittently, but the suction pressure will be very low, and the exhaust pressure will remain almost unchanged. This frequently triggers low-pressure protection or compressor overheating protection shutdown. 2. Working principle: Gas passes through a long tube (usually coiled into a solenoid), allowing heat to dissipate into the surrounding air. Metals like copper, with strong thermal conductivity, are commonly used to transport vapor. To improve the condenser's efficiency, heat-conducting fins with excellent thermal performance are often attached to the pipes to increase the heat dissipation area, accelerate heat dissipation, and enhance air convection through a fan to carry away the heat.
