Why does the car air conditioner not cool at idle but cools when accelerating?

[FrankDella]

If the car air conditioner does not cool at idle but cools when accelerating, the possible reasons are belt slippage or damage to the air conditioning compressor. Here is an introduction to car air conditioning knowledge: 1. Definition: The car air conditioning system, referred to as car air conditioning, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. It provides a comfortable riding environment for passengers, reducing travel fatigue; it creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device. 2. Types of air conditioning: According to the driving method, it is divided into: independent type (a dedicated engine drives the compressor, with large cooling capacity and stable operation, but high cost, large volume and weight, mostly used in large and medium-sized buses) and non-independent type (the air conditioning compressor is driven by the car engine, and the cooling performance is greatly affected by the engine operation, with poor stability, mostly used in small buses and cars).
