Big river - river newspaper reported on May 25 As temperatures rise, more and more car owners have begun to use air conditioning. While enjoying the cool at the same time, many owners, especially each time more than half an hour's drive car owners will feel sense of discomfort, and even feel dizziness, vertigo, nausea and loss of appetite, or will feel discomfort, chest tightness, and muscle weakness of the lungs. Some owners considered himself for car air conditioning is not to. Actually this kind of phenomenon in medicine known as the "auto air-condition disease". How are they? Summarize the following error, remind everybody pay more attention!
The working principle of the air conditioning refrigeration
Is our most people believe that air conditioning refrigeration equipment, a typical structure including the air conditioning compressor, condenser, cooling fans, expansion valve, evaporator and condenser blower and related air conditioning pipe. Filling the refrigerant inside the closed system, circulation flow under the action of refrigerant in the compressor, condenser in nacelle by gas liquid to liquid, gives off heat. And in the car by the liquid evaporated into gas, absorption of heat, thus reducing the car's temperature.
Clean is very important
Some owners are always wait until air conditioning performance is bad, think of cleaning air conditioning, this is not correct. Air-conditioning filter to change regularly, because of the large spring dust, catkin scud, these will touch on the filter, easy to breed bacteria, mildew, so it's best to change after a spring air conditioner filter.
Clean with cleaner is also a necessary step, before disinfection, should remove the car's food, paper towels, avoid adsorption odor. Find car external air import, if there is need to open the hood; Start the engine, open the window; Puts the AC gear of the air conditioning OFF, to gear to the circulation loop, fan open to maximum; The strongest position to guide outside the car port suction injection air conditioning cleaning agent; Detergent will flow in the direction of the evaporator, cleaning the mold on adsorption in the evaporator, dust; All after injection, to rotate the fan continues to 10 to 15 minutes; After 10 minutes, fluids by drain out of the car, clean air air-conditioning outlet is sent out.
Here to remind you the owner, general traffic in the city, three thousand km or so we need to replace the air filter, such not only can let the air intake system cleaner, also can avoid because the air conditioning filter clogging caused refrigeration capacity decline.
Ventilation, and then choose the way to air condition
Habit of a lot of owners into the car is open air conditioning circulation, think that can let the car temperature drop faster. Actually this is wrong! Because the temperature of the inside than the outside temperature is high, air conditioning cold wind blow to the body, it is easy to catch a cold diarrhea. Just into the car, should open a window ventilated, and open loop, all the heat out. Such as car temperature drop, and then to the inner loop.
Do not to blow air conditioning
Some owners do not pay attention to adjust the outlet direction, at that time, met The Times great blow a cold wind over straight, but also easy to blow out of arthritis. And is not conducive to air conditioning refrigeration effect, according to the principle of cold air sinks, hot air rises, the correct approach is, the outlet up, turn on the air conditioner down when the steam outlet.
In addition, air conditioning temperature also shoulds not be too low. General advice about the car air conditioning temperature control at 26 ℃ for good, and get off at the general situation in the temperature and the external environment temperature differs 6-7 ℃ is better.
Air conditioning don't open too long
After many owners into the car, has been open air conditioning, in low temperature environment can stimulate vascular contraction, blood circulation, guide hands and feet numbness, cold, waist and back stiffness influence driving safety. And long time use of air conditioning can make the condenser pressure is too large, will cause loss to the refrigeration system. So open air conditioning time shoulds not be too long, the temperature inside the car to reach a comfortable temperature, the air conditioning can be turned off, to open every once in a while.
If there is hot day, when driving, internal and external circulation system should be often switch, to ensure that the car has enough "fresh air".
Note that the car "PM2.5"
Nose sensitive owners, more should pay special attention to the concept of "PM2.5" inside the car. In general, the car's air purification equipment such as pollen can get fine dust, but the car air conditioning alone ordinary filter is difficult to completely filter out particles PM2.5 levels. At the same time, long time to open the air conditioning in summer, the car is a relatively dense space, are more likely to cause respiratory disease, for nasal sensitive owners, but also a big threat to health. Owners can choose according to bear ability using PM2.5 air conditioner filter.
After the rain's going to be a warm wind, clear mildew flavour allergy free
After the rain, the car tends to have a little musty, encounter this kind of situation can dispatch warm wind to maximum, 20 minutes or so, keep the moisture quickly evaporate. Or in the sun to open doors and trunk, thoroughly ventilated platoon is wet, avoid the skin sensitive lady get on allergy. It is best not to use perfume to cover up like mold, because some funky is caused by the perfume, such as acidic lemon flavour perfume, easier to produce mildew smell after sending out.
