With the summer coming, the weather becomes more and more hot. You may need a combination of watermelon and air conditioner, especially when drive a car in hot summer. However, drivers often have such problem that the air conditioner is working, but it’s still hot inside the car. What cause such problem?
Before analyze the reasons, let’s see the working method of air conditioner is cars. The parts of air conditioner are separate in the cars. Thus it need an air conditioner hose to connect these parts together. Then it makes the whole air conditioner system work regularly.
First, the air compressor deliver the refrigerant to the condenser. Then the high pressure refrigerant liquefy and release heat, which will be took by the air outside. Second, high pressure liquid refrigerant reduce pressure in the expansion valve. Then the low pressure refrigerant absorb heat in the evaporator. Then the cooling air blow to the car. Last, compressor take out the air refrigerant and pump it to the evaporator. Therefore, the refrigerant can circle inside the car and make the temperature low down.
Knowing the working method, we can analyze the reasons why it’s still hot when the air conditioner working.
Block of air conditioner hose
As I mentioned above, the parts of air condition system are separate in the car and they connect with each other with air conditioner hoses. While the refrigerant flows inside these hoses. Thus if some of the hoses block, the refrigerant will not able to deliver to the car. The heat can not to take out the are as well. What’s more, the impurity inside the air conditioner hose may cause germ. Therefore, you should clean the air conditioner hose regularly.
