14.9.2. That everything worked


In order that 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 effectively work, when in the car all windows, and also the hatch are closed. Quicker to cool salon in very hot day, it is necessary for a minute – another to open all doors and when the car will blow – everything to close and turn on the conditioner (at the working engine).

Draining influence of the conditioner reduces a zapotevaniye wind and lateral glasses of salon therefore sometimes the conditioner is useful for including at the same time with an oven. However, some climatic systems do not provide simultaneous operation of the conditioner and an oven.

In central air there is an oil which circulates together with a coolant. If the system long stays idle, its some details, in particular, neoprene laying, dries up and collapses, leaking. Therefore it is desirable to turn on once a week the conditioner not less, than for ten minutes, including in the winter that oil 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 complete pumping and downloading new is required the professional equipment and to provide full tightness, special high-sensitivity devices for identification of leaks are necessary.

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

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

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

Receives damage the condenser more often. It is located before an automobile radiator and protected by only a radiatorny lattice.

The second problem is failure of the needle gate (it is hammered by dirt). Cleaning the gate, it is necessary to remove from it 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 a condition of a driving belt. The compressor is given in some cars by a separate belt. It is successful option. However modern cars are often equipped with 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 after all there was a leakage of a coolant through rubber hoses, their replacement is quite problematic, as it is difficult reliable загерметизировать new hoses on an old aluminum fitting.

Keep in mind that the conditioner can not turn on, if the surrounding temperature is lower set or if pressure in system is much lower (leakage of a coolant) or above the optimum.

To violations in operation of the conditioner bring also excess of oil, a coolant, hit into 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 proskalzyvany couplings of the compressor.
