Car air conditioning refrigeration is poor, odor how to do?

In the hot summer, the era of car sauna opens, if the car air conditioning is not strong, then driving is completely a torture.

Next, Master Bang will explain to you why the car refrigeration effect is poor and there is an odor.

Why is the cooling effect of air conditioning poor

1

Insufficient refrigerant

Only when there is enough refrigerant in the car air conditioning system, can the heat be effectively taken away, so as to achieve the purpose of cooling, if the refrigerant content is insufficient, the air conditioning refrigeration effect will become worse.

2

Line clogging

There are many pipes connecting the condenser to the evaporator, and the refrigerant flows in these pipes. If the pipeline is blocked, the refrigerant can not flow smoothly, can not effectively transfer heat, and the cooling effect will become worse.

3

The cold air filter is blocked

The refrigeration effect of air conditioning is poor, and there is a more direct reason, because the air filter is blocked and the amount of air blown out of the outlet is too small.

4

The cooling effect of the condenser is not good

If the condenser fin is blocked by dirt, it will make the liquefaction effect of the condensing agent worse, and it will also lead to the refrigeration effect of the air conditioner

Why does the air conditioner smell

1

The air conditioner filter element is dirty

Car air conditioning filter is a "filter barrier" for the air outside the car to enter the car, if the car air conditioning filter is dirty and not replaced for a long time, it will not only affect the car cooling effect, but also pollute the air in the car and produce odor, so it must be replaced regularly.

2

The evaporation box is dirty

The evaporation box of the air conditioner is located inside the instrument panel. When the air conditioner is opened, the cold and heat exchange of the evaporation box is required to produce a large amount of condensed water on its surface. At the same time, the entry of outdoor air may carry a variety of dust mites, bacteria, impurities, etc., which are adhered to the surface of the evaporation box with condensed water. Over time, these dirty things, along with dust and condensation of water droplets in the evaporation tank, will develop mold, resulting in odor.

3

The air duct of the air conditioner is dirty

Air conditioning duct is the air duct, air conditioning duct is easy to accumulate dust, but it is often ignored by people, if after cleaning the air conditioning filter and evaporation box, the odor is still not eliminated, then the probability is that the air conditioning duct is dirty, bacteria concentration caused by the odor.

Master Bang tips: summer is the time for bacterial proliferation, for air conditioning maintenance must be timely.
