What Causes Poor Cooling in Car Air Conditioning During Summer?
1 Answers
The reasons for poor cooling in car air conditioning during summer include inferior quality of refrigerant, among others. Below is an introduction to the causes of poor cooling in car air conditioning during summer: 1. Quality and Purity of Refrigerant: The quality and purity of refrigerant play a crucial role in car air conditioning. Inferior refrigerant often leads to low operational efficiency of the air conditioning system. 2. Condenser and Radiator: The heat dissipation condition of the condenser and radiator affects the performance of the air conditioning. Long-term accumulation of dust and debris can cover the condenser and radiator if not cleaned regularly. 3. Refrigerant Usage: More refrigerant in the air conditioning system is not necessarily better. During the refrigerant charging process, the amount must be neither too much nor too little. Insufficient refrigerant results in inadequate pressure in the air conditioning pipes, while excessive refrigerant causes excessive pressure. In both scenarios, the air conditioning system cannot operate normally to provide cooling. 4. Quality of the Expansion Valve: The expansion valve is a critical component in the refrigeration system, typically installed between the liquid storage tank and the evaporator. An inferior expansion valve can prevent the refrigerant from functioning as intended.
