We are accustomed to comfortable conditions and now can not imagine my life without the various devices to facilitate it.In winter, we warm electric and gas heaters.Summer heat helps to survive the air conditioning.It happens that, in spite of the appearance of the work, its function of cooling air is a useful device does not perform.What if it happened?
Go to the shop?
So what if the air conditioner does not cool?You can answer this question in the same manner as that of a doctor, when to him for advice addressed party guests: "Address to the expert!" But it happens that the master is not needed, just follow some simple operation, and theneverything will be alright.In order to distinguish this situation from another, when to do without a visit to a service center or a specialized service station (if the car air conditioner does not cool the air) can not, you should at least familiarize yourself with the general principle of the right of the appliance.
The principle of cooling
All air conditioners operate on the same principle.Moreover, they are blood relatives even more prevalent in the home device, a refrigerator.And they function is quite simple.The reasons why the air conditioner does not cool, can be the same, which does not want to freeze the refrigerator.
all railway conductors known little secret, without allowing electrical appliances even in the hottest midday passengers wishing to provide cold drinks.Suffice it to a bottle or jar wrapped in a wet towel and put this combination of the window.Fast carrier car is in the air stream and vaporization of water occurs rapidly.This heat is removed from the glass or aluminum containers.The reverse process - condensation heat when it is consumed.This principle works all hladotehnika, from small bar refrigerators to large port facilities, bearing the same name.
What is air conditioning
to operate air conditioning, it must include five serviceable components: evaporator, condenser, compressor, fan and throttle.As is clear from the previous section, the evaporator is a selection of heat from the room air.But this is not enough, the energy must be removed, otherwise, according to the law to preserve it, it will remain in an insulated isolated space.The same refrigerator if its just open the door in a closed room, working, do not cool it down, but instead raise the temperature a little (due to heating of the motor).
heat release to the environment takes place in a condenser in which coolant (inert gas) pumps the compressor, compressing it and converting into a liquid, that is condensing.It accelerates the process of heat exchange ventilator.Choke (this is a valve) is the regulator of the cooling rate, it is often paired with an automated control circuit receiving the information from the sensor.It compares the set and actual temperature and produces a control action, expressed opening or closing the throttle.That's all.
most common failure
The most common reason why the air conditioner cools the bad (or even rides the warm air suddenly becoming conventional fan), is leaking refrigerant.It is expressed in a violation of the integrity of a closed loop, which circulates the inert gas in the condenser becoming liquid.Actually, the ideal in nature do not happen, and sooner or later it happens.In this situation, to cope with the task virtually impossible.For the filling of freon needed: special equipment, a gas cylinder, and the skills to fill them to the system.In addition, the likely need to locate the leak (somewhere evaporated as coolant), otherwise the procedure will be repeated soon.
Other causes of inefficient operation
very important in the climate system air filter.If it is clogged, it is not enough that the air conditioner does not cool, there is a danger of contracting some dangerous virus.Bacilli in the filter accumulates a lot, they are released into the air breathed by occupants of the room.Change the consumables can be yourself.
else happens hammer outputting system failure.This happens when you try to turn on the device at very low temperature (which in fact is meaningless).In this case, the compressor gets no gas, as expected, but the liquid did not had time to evaporate.If it really happened, you need to contact the service center.
In very hot weather, some motorists complain about the fact that the air conditioning in the car does not cool the air.In this case, the rush to the service station is not necessary and should follow simple rules.
Firstly, it is best to leave his "iron horse" in the shade or close the windshield foil curtain.If the air in the cabin is still too hot, do not need to immediately include air conditioning.It does not warm it may be because it simply takes time to come to a working state.A dozen kilometers "with the wind" cool the excessive zeal, he will appreciate the freshness back.
Secondly, the air conditioner does not need to immediately "cut in on all cylinders," better to start with the smallest position of the regulator to give the device gradually "break up."
Third, setting off climate properly when the engine is running, so as not to overload the vehicle power supply circuit transients.
And fourthly, if any doubt still see a specialist.
