Car air conditioning is not cooling on that do you understand it？

The climate gradually heat up, but also to the peak of the use of automotive air conditioning, in order to cool car faithful will open air conditioning. But there are problems so that many owners are very confused, that is, car air conditioning is not cooling, blowing the wind is not cool. What about it? Once this situation is presented, it is necessary to use useful measures to deal with. Car air conditioning inside some of the components is very important, showing problems will affect its cooling effect, had only two simple steps, slightly moving hands can handle.

The first step is to clean the condenser and filter.

Air conditioning inside the condenser is too dirty, the demand for timely clean, many people usually too lazy to clean the condenser, the dust above the accumulation of thicker and thicker, resulting in poor heat, seriously affecting the cooling effect. Cleaning the condenser is not difficult, at home when the car wash, first prepared a bucket of water, scrub with a rag carefully scrub again, mainly to the above dust stains removed clean like.

There is the air conditioning filter is blocked, resulting in air conditioning is not cooling the situation, then we have to clean the air conditioning filter, if the damage to the network may be serious, the direct change to a new.

The second step, increase the refrigerant

After the above steps are completed, and then try the cooling effect of air conditioning, if still not cooling, it is likely that the air conditioning system, lack of refrigerant. Since the refrigerant injected from the expansion valve into the evaporator is reduced, the heat absorbed by the refrigerant is small, so that the cooling effect is poor. At this time should increase the refrigerant, but there must be a little attention, the refrigerant bottle can not be taken backwards.

If you want the role of air conditioning and refrigeration more ambitious, in addition to the above two steps, the general maintenance of automotive air conditioning can not carelessly.
