Repair and car operation

14.9.2. That all worked

THE GENERAL DATA

That the central air well worked, it is necessary to be able to address with it. For example, many do not know that the conditioner only then will work effectively when in the car all windows, and also the hatch are closed. Faster to cool salon in very hot day, it is necessary to open all doors and when the car will blow for a minute-other – all to close and include the conditioner (at the working engine).

Draining influence of the conditioner reduces запотевание wind and lateral glasses of salon, therefore sometimes the conditioner is useful for including simultaneously with an oven. However, some climatic systems do not provide simultaneous work of the conditioner and an oven.

In a central air there is an oil which circulates together with a coolant. If the system long stays idle, its some details, in particular, неопреновые linings, dry up and collapse, springing a leak. Therefore it is desirable to include once a week the conditioner not less, than for ten minutes, including in the winter that oil has greased all knots of system.

What it is possible to repair?

Conditioners are not subject to "house", amateur repair. The coolant – substance whimsical, for its full откачки and закачки new is required the professional equipment and to provide full tightness, special high-sensitivity devices for revealing of leaks are necessary.

If the conditioner has broken, means, at least, it is necessary to replace any details, including special tubes and фитинги, but there is a set of their standard sizes. And special blooming adaptations are applied to fastening of tubes to фитингам.

So, if you had problems with the conditioner, rely only on experts. Address in firms which make difficult repair, and not just закачивают the disappeared coolant. If the coolant "has left" system in the beginning it is necessary to find the reason, differently the new coolant will disappear in the same way!

Similarly, if at you has jammed the compressor simply to replace it insufficiently: in some months it again will jam. It is necessary to remove in the beginning from system a shaving and other dust, and then to wash out its special solution or nitrogen. It is necessary to replace also a receiver-dehumidifier (in it there was a shaving) and закачать a fresh coolant.

More often receives damage the condenser. It is located before an automobile radiator and protected only радиаторной by a lattice.

The second problem is refusal of the needle gate (it is hammered by a dirt). Cleaning the gate, it is necessary to remove from it a dirt, instead of to push it inside!

There are also other problems – for example, the compressor rustles. Usually, it speaks about its close end.

It is easy to check up a condition drive a belt. In some cars the compressor is resulted by a separate belt. It is a successful variant. However modern cars are often equipped by a long "multipurpose" belt which actuates at once some devices, often, including, and the water pump. So, if the bearing of a leading pulley of the compressor of the conditioner suddenly will jam, you will not leave anywhere, yet will not find a belt of the smaller size to "bypass" the compressor!

Other aspects

If all the same there was a coolant leak through rubber hoses their replacement is problematic enough as it is difficultly reliable загерметизировать new hoses on old aluminium фитингах.

Keep in mind that the conditioner can not join, if the surrounding temperature below set or if pressure in system much more low (coolant leak) or above the optimum.

In infringements in conditioner work result also surplus of oil, a coolant, hit in air or moisture system, strong pollution of edges of the condenser or the evaporator, malfunction of system of cooling of the car (overheat), and also проскальзывание муфты the compressor.
