Why do cars drip when heated?

This situation may be affected by the leakage of antifreeze. After this happens, you should check the cooling system of the car. The car is heated by the heat of the engine. When the air conditioner is turned on, the high-temperature antifreeze in the engine will flow through the heater box. At this time, the wind from the blower may also pass through the warm air tank, so that the air conditioning outlet of the car can blow out warm air. Automobile air conditioner is an important comfortable equipment in automobile, which can be used for cooling or heating. When cooling, the compressor clutch will be engaged, and the engine will drive the compressor to run. When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporation box. The refrigerant continuously expands and absorbs heat in the evaporation box, so that the refrigerant cools the evaporation box. The cooling evaporation box can cool the wind from the blower, so that the air outlet of the automobile air conditioner can blow out cold air. The refrigerant used in automobile air conditioning is r 134a, which needs to be added regularly. If refrigerant is not added for a long time, it will affect the refrigeration effect of automobile air conditioner and slow down the refrigeration speed. Naturally, friends are encouraged to add refrigerant regularly when using the car. When using the car at ordinary times, the air conditioning system of the car must also be cleaned regularly. Long-term use of automobile air conditioning system will breed a lot of bacteria inside, and if it is not cleaned for a long time, it will affect the health of passengers in the car.
