What to Do When the Car Air Conditioner Is Not Cooling?
1 Answers
Insufficient refrigerant due to low refrigerant levels. The primary cause is often minor leaks in the system. If there is insufficient refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will correspondingly decrease, leading to reduced heat absorption during evaporation in the evaporator and consequently diminished cooling capacity. Below is information regarding why a car air conditioner may not cool properly: 1. Air in the system can also cause insufficient cooling. Once air enters the air conditioning system, it can result in excessively high pressure in the refrigerant lines or poor refrigerant circulation, both of which can lead to inadequate cooling. This is mainly due to compromised system sealing or incomplete vacuuming during maintenance. 2. Excessive refrigerant can also cause insufficient cooling. Overcharging the refrigerant, typically occurring during maintenance, can lead to this issue. The proportion of refrigerant in the air conditioning system must meet specific requirements; if it exceeds the optimal level, it can negatively affect heat dissipation, where more heat dissipation means greater cooling capacity. 3. If the compressor is damaged and cannot engage, the air conditioner will not cool. If the refrigerant is sufficient but the air conditioner still fails to cool at all, the compressor may have stopped working, necessitating repair or replacement.
