High temperatures, rainy summer's two most notable features of these run the car also has a great impact, the car has a lot of faults occurring in summer and climatic characteristics with no small contact. Special margin fan clutch for your car air conditioner to explain some details to note:

   Temperature is not too low

    Due to hot weather it was cool to be able to quickly, many owners prefer to tune the temperature is too low, the air volume to maximum, seem to feel cool and very comfortable. But this for our own health will have an impact, when people suddenly switch from heat to cool the ambient environment, the body's endocrine system can not immediately adjust to come, this will cause occupants sick. Under normal circumstances, the inside temperature and the outside temperature difference should be 5 ℃ to 6 ℃, now is not in advocating indoor 26 ℃ is the most comfortable and healthy temperature right, then it may be the car in the summer air conditioning set at this temperature, Select the appropriate air temperature, to ensure good health.

    Do not rush to open air

    Car outside the sun baked hotter inside the car will, I believe this is the first reaction when you want to quickly open air cooling. In fact, this cooling effect is not good, because the car and the air inside the air conditioning pipe bursts in the sun for a long time under the sun the temperature is high, if this open air from a vent blowing out hot air directly to you, make you more feel uncomfortable. The correct approach is to first before the car windows open to allow air through convection discharged inside the vehicle; simultaneously open air hair, let the hot air inside the air conditioning ducts and then blowing out, not long enough for 20-30s, This time off the windows and then open air conditioning and refrigeration, the effect will be much better.

    Open the appropriate amount of wind

    Some owners do not like air conditioning because the noise emitted into high gear when open, so rarely or never open to the winds of the air conditioner. Will be sucked into the air conditioning use a lot of dust, winds can periodically open the air-conditioning duct surface dust blown out, which is to maintain a clean, simple way to air-conditioning. Also note that when you open up the air-conditioning outlet, the outlet downwards open heating.

    For a long time to open the inner loop

    Circulating in the air circulation inside the closed space, the oxygen content of the vehicle will continue to decline, and if the cylinder gasoline incomplete combustion engine to make the unburned carbon monoxide may leak into the compartment, and therefore the car Air quality will continue to deteriorate, and even cause harm to humans. Therefore, while the inner loop should be opened, while the outer loop to open to let fresh air into the cabin.

    First turn off the air conditioning off again

    Some owners are often remembered after flameout close the air, which is harmful to the engine, because this next time you start the vehicle, the engine will start with the air-conditioning load, such a high load can damage the engine. So every time the destination is not far away when the first air conditioning systems shut down, but also in the vehicle should be started two or three minutes after the engine is lubricated, and then turn on the air. This will not only protect the vehicle and better, while avoiding the propagation of mold, thus avoiding the generation of air conditioner odors.

    Try not to smoke in open air

    For smoking friends, when the car air conditioning, it is best not to smoke in the car, the vehicle air pollution is very serious. If you're stubborn, then please air conditioning ventilation control transferred to the outer loop position. Also note that, to remember not suspended the air-conditioned car for a long time to rest or sleep. Because the vehicle suspended, driving inside a closed car air conditioning ventilation is poor, if this time open air rest or sleep, probably due to the leakage of harmful exhaust gases of the engine into the car cause poisoning and even life-threatening.

    Before we introduce some important points about the use of air conditioning, air conditioning in the course then what kind of problem it would appear, such as the interior temperature is high enough, but the lack of cool air conditioning, a long time there will be some wind blowing out odor so, here we come to you on how to care for and clean air.

    First special margin fan clutch , and we take a look at the car air conditioner is probably constructed. Automotive air conditioning compressor motor controlled mainly by the general clutch, condenser, evaporator, expansion valve, Drier, pipes, condenser fan, vacuum solenoid valve, idle and control systems and other components. Automotive air conditioning of high-voltage lines and low pressure pipeline. Including the output side of the high pressure side of the compressor, high pressure piping, condensers, liquid storage and liquid line drier; low side including evaporators, accumulation, a return line, the input side of the compressor and compressor oil pool.

    Note periodic inspection

    Air conditioning cleaning cycle is usually every six months, before and after prolonged use of air conditioning maintenance can be carried out once. Some experts suggested that even in winter the best able to open one or two air-conditioning, activate various components so that they remain in good working condition. If there have been odor, check the mold problem. General filter mildew can be resolved by simply washing with water, activated carbon filter material if it is to find the best professional treatment or to replace the new filter. If the air conditioner does not cool the situation needs to pay attention to the quality and purity fluoride, fluorine quality and purity has played a crucial role in vehicle air conditioning, usually inferior fluoride can lead to poor air conditioning operation efficiency.

    Clean air to replace the air filter

    Automotive air conditioning cleaning has two methods: one method is to wash washable, washable method is very troublesome, it is recommended not to individual operations. Another method is to use a dedicated automotive air conditioning cleaning agent directly to clean, wash cars abroad is currently the most commonly used method for air-conditioning. Materials needed for air conditioning filter, auto air conditioning, cleaning agents and sterilizing deodorant.

    Air filter variety, generally divided into three categories: activated carbon grain type, active carbon and non-carbon-based type, usually in the major electricity supplier site can buy, a reasonable choice based on condition of the vehicles.

    Automotive air conditioning is not cooling or inadequate air-conditioner failure is a common, more common in the cooling system sealing problems, because the refrigerant R134a used in modern cars permeability sake. Summed up in three main areas: air-conditioning system of mechanical failure, the air conditioning system electrical circuit fault, refrigerant and refrigerant oil failure.

  First, the air conditioning system of mechanical failure

    Mechanical failure include air-conditioning system compressor failure, condenser and fan failure, blower failure, reservoir dryer, expansion valve and evaporator fault fault. Determine whether the compressor drive belt failure depends on whether the aging, cracked, loose or too tight, the impact of power transmission. Internal parts damaged or worn, the impact of the compression performance, the performance of the internal compressor abnormal noise. Channeling gas compressor cylinder head gasket, intake and exhaust valve damage, the impact of the compression performance.

    Condensers and heat sink fan failure mainly to see whether it is covered by oil, dust, impact of heat. Fan is running well. Blower failure depends functioning properly, may lead to insufficient air flow. Reservoir containing the filter drier is to see and desiccant. Filter is clogged, it may affect the refrigerant flow; desiccant whether the failure, affecting water absorption capacity, may cause ice block. Normal desiccant is blue, the desiccant is saturated with water red. Look through the expansion valve failure of the expansion valve port to control the opening and closing of the refrigerant entering the evaporator the liquid flow, regulate the cooling capacity. If the valve is too large mouth always open, the refrigerant flows to the evaporator surface due to cold frost, causing the cooling time to stop; If the valve is always open mouth is too small, the refrigerant flows into a small volume, resulting in insufficient cooling. Evaporator fins depends on whether it is oil, dust cover, the impact of heat exchange; whether deformation.

    Second, the air-conditioning system electrical circuit malfunction

    Pressure sensors, temperature sensors, thermostat, compressor electromagnetic clutch, high and low pressure protection switch, expansion valve bulb and so on.

    Third, the refrigerant and refrigerant oil caused by the failure

    Failures caused by refrigerant and refrigerant oil, for many reasons, including lack of refrigerant caused by excessive cooling, refrigerant shortage caused by too little refrigerant, the refrigerant and refrigerant oil contains too many impurities, caused by lack of micro-blocking cooling capacity, air conditioning and refrigeration the system has insufficient cooling water caused by infiltration, the system has resulted in insufficient cooling air and low-grade oil caused by lack of refrigeration and refrigeration.

    According to Yu-fan clutch special note, if too much refrigerant, heat dissipation slow. If added too much maintenance refrigeration oil, the refrigeration system will also decrease the amount of heat. Repair methods: observation from above a dry tank sight glass. If the air conditioning in the car running from the sight glass can not see a little bubble, no bubble after a compressor stall, it is certainly too much refrigerant. If excessive amount of oil added to the refrigeration, air-conditioning system during normal operation, from the sight glass opacities seen more bubbles. If indeed excessive cooling agent can be repaired at the mouth of the low pressure side of the air conditioning system and slowly release some can be.

    Most of the causes is due to the shortage of refrigerant in the refrigerant system micro leaks. Inspection method: to be shortage of refrigerant liquid mirror as viewed from the top of the tank to the drying, when the air conditioner normal operation, if the sight glass with slow continuous bubble generation, the refrigerant shortage. If the apparent air bubbles appear flip, then a serious shortage of refrigerant
