What are the reasons for poor cooling performance of car air conditioners when there is no lack of refrigerant?
1 Answers
Car air conditioners may have poor cooling performance even when there is no lack of refrigerant due to the following reasons: the quality and purity of the refrigerant. Low-quality refrigerant can lead to inefficient operation of the air conditioning system. The condenser and radiator, if not cleaned for a long time, can become covered with dust and debris. The quality of the expansion valve, which is a crucial component in the refrigeration system typically installed between the liquid storage tank and the evaporator. A substandard expansion valve can prevent the refrigerant from functioning as intended. Below are additional details: Common factors affecting car air conditioner cooling performance: The quality and purity of the refrigerant play a vital role in the performance of the car air conditioning system. Typically, low-quality refrigerant results in reduced operational efficiency. The heat dissipation of the condenser and radiator also impacts the air conditioner's performance. Prolonged lack of cleaning can cause these components to become covered with dust and debris. Many car owners believe that more refrigerant is better for the air conditioner, but this is not the case. During the refrigerant charging process, the amount must be neither too much nor too little. Insufficient refrigerant leads to inadequate pressure in the air conditioning pipes, while excessive refrigerant causes excessive pressure. In both scenarios, the air conditioner will not function properly and will fail to cool effectively.
