What are the reasons for poor air conditioning cooling effect in Audi Q5?

[DiJames]

It could be due to insufficient cooling capacity of the air conditioning system, poor heat dissipation leading to inadequate cooling, or poor sealing inside the vehicle. Below is relevant information: 1. Fault diagnosis and troubleshooting: Hot air entering through gaps in air ducts, repair sealing strips. Poor operation of control dampers in the heating assembly, improper adjustment of control cables, repair linkage rods or replace the heating assembly. 2. Working principle: The automotive air conditioning refrigeration system consists of compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a sealed system. During operation, the refrigerant circulates through this sealed system in different states, with each cycle consisting of four basic processes.
