The reasons for the Wuling Hongguang miniev's air conditioning not being cold are as follows: 1. Insufficient refrigerant: The main cause of insufficient refrigerant is usually a leak in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease, leading to a reduction in the heat absorbed during evaporation in the evaporator, thereby decreasing the cooling capacity. 2. Contaminants: Excessive impurities in the refrigerant and compressor oil can cause minor blockages, resulting in insufficient cooling capacity. If there are too many contaminants in the refrigerant and compressor oil throughout the air conditioning system, the filter screen of the filter will inevitably become clogged, reducing the flow capacity of the refrigerant, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, thus leading to insufficient cooling capacity. 3. Air conditioning compressor: A loose drive belt on the air conditioning compressor can cause slippage during operation, reducing transmission efficiency, lowering the compressor's speed, and decreasing the delivery of compressed refrigerant, which directly reduces the cooling capacity of the air conditioning system.
