Here are the reasons why a car's air conditioning cannot cool: 1. The compressor is not working: for example, the compressor capacitor is damaged or not working properly; 2. The car's air conditioning belt is too loose; 3. Refrigerant leakage in the air conditioning system; 4. Problems with the condenser: After long-term driving, the condenser accumulates a lot of dust. When there is too much dust on the condenser, the heat dissipation effect is poor, and the air conditioning naturally does not cool. The solutions for a car's air conditioning not cooling are as follows: 1. Repair or replace the compressor; 2. Adjust the belt tension; 3. Add refrigerant to the air conditioning system; 4. Clean the condenser. It is recommended to promptly visit a 4S store or a professional auto repair shop.

While driving, I noticed the air conditioning wasn't cooling. The most common issue is refrigerant leakage. Last time my car had this problem, it became unbearably hot inside. After repairs, I learned there was a leak in the pipeline, and replacing the refrigerant fixed it. Compressor failure can also be a cause – the compressor might make squeaking noises or fail to start. Blocked fans or condensers can reduce cooling efficiency. A heavily clogged air filter restricts airflow, leading to poor cooling. Regular maintenance can prevent these issues, like checking the AC system at the start of each season to ensure all components are working properly, making for a more worry-free drive.

When the air conditioning is not cooling, my experience is often due to insufficient refrigerant or a leak. Check if the compressor is running normally; if there are no unusual noises, it might just need a refrigerant top-up. Fan issues can also hinder cooling performance, such as stuck blades or a faulty motor. Dirty filters need to be cleaned, otherwise, airflow will be obstructed. Electrical problems in the system, like sensor failure, can also cause malfunctions. Pay attention to temperature changes while driving, and if any issues are detected, promptly visit a repair shop for diagnosis to avoid minor problems turning into major repairs.

My car's AC had similar issues before, mostly due to insufficient refrigerant or system blockage. Check if the compressor can start and whether the fan is running. Clogged filters have a big impact—it'll improve after cleaning. Simple repairs like recharging refrigerant can fix it, but make sure to repair any leaks. Address it promptly while driving to avoid suffering in hot weather.

What to Do If the Car Water Pump Is Leaking?

Solutions for car water pump leakage: 1. If the leakage is at the pipe connection, it is less likely to occur with a newly installed pump. It is recommended to disassemble and reinstall. 2. If the pump leaks while pumping water, it is usually due to a leaking water seal. It is advised to disassemble the pump and replace the water seal. 3. Long-term leakage may be caused by the absence of a check valve on the outlet side of the pump. It is recommended to install a check valve. Working principle of the car water pump: The engine drives the pump bearing and impeller through the pulley. The coolant in the pump is rotated by the impeller and, under centrifugal force, is thrown to the edge of the pump housing, generating pressure before flowing out through the outlet or pipe. The center of the impeller experiences reduced pressure as the coolant is thrown outward, causing coolant from the radiator to be drawn into the impeller through the pipe due to the pressure difference between the pump inlet and the impeller center, achieving a reciprocating cycle of the coolant.

What is the cooling principle of car air conditioning?

Car air conditioning cooling principle refers to the operational mechanism of air conditioning refrigeration. After the air conditioner is powered on, the low-pressure refrigerant vapor in the refrigeration system is sucked in and compressed into high-pressure vapor by the compressor, then discharged to the condenser. The indoor air continuously circulates, achieving the purpose of lowering the temperature. The outdoor air drawn in by the axial fan flows through the condenser, carrying away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into high-pressure liquid. The high-pressure liquid passes through the filter and throttle mechanism before being sprayed into the evaporator, where it evaporates under the corresponding low pressure, absorbing heat from the surroundings. Simultaneously, the cross-flow fan causes air to continuously enter the spaces between the evaporator fins for heat exchange, and the cooled air after releasing heat is directed into the cabin.
