What Causes Insufficient Cooling in Truck Air Conditioning?

[SanAvery]

Truck air conditioning may not cool properly due to reasons such as insufficient refrigerant or damaged air conditioning flaps. Below are the key factors affecting truck AC cooling performance: 1. Poor refrigerant quality and purity: The quality and purity of refrigerant play a crucial role in vehicle air conditioning systems. Typically, inferior refrigerant leads to inefficient AC operation. 2. Dirty condenser and radiator: The heat dissipation condition of the condenser and radiator significantly impacts AC performance. Long-term accumulation of dust and debris can cover these components. 3. Incorrect refrigerant charge amount: Many truck owners mistakenly believe more refrigerant is better. In reality, the refrigerant charge must be precisely measured - insufficient pressure prevents proper cooling, while excessive pressure also hinders system operation. Both conditions will result in failed refrigeration function.
