Why is conditioned air smell: air-conditioning system began sending wind smell, because: (1) the system is not running for a long time, between the heat exchanger fins have choked. (2) some of the air terminal non-efficient filter systems, such as computer rooms, hotel rooms, etc., although the interior is good, fresh air, filtered air supply are processed, but near the surface and some indoor windowsill outlet can still be found in dust on the surface but also inside the adhesion layer of dust. (3) air-conditioning system starts, the indoor concentration of bacteria and odor actually increased, this is due to the heat exchange coils, fins and the peripheral portion of the condensed water slowly evaporate stranded coil formed around the high humidity (and high temperature, because it has shut down) the conditions become suitable environment for microbial growth, a lot of gas is generated as a result of the breeding system driven by the sudden release of Xuzhou hand air conditioning recovery, become the source of the stench. Is said to bring a new style and a lot of dust accumulated in these areas not only carry the microbes, but also for microbial growth and provide an essential nutrient conditions. The root cause of these problems Xuzhou several telephone central air conditioning maintenance, new air filter is not properly handled. Generally new air conditioning system or fresh air filtering machine filter only coarse filter, if the so-called tertiary filtration purification system: in effect coarse fresh air, return air, air supply and efficient model, will improve indoor air quality. Do you want to install and use the air conditioner to ignore the power of a question from a friend to buy a window air-conditioning unit, the use of too much noise. Began to think that the problem is to install, but also reinforcement is damping, the results do not work. Measured with a multimeter power supply voltage is 210 volts when not turned on, and then turn it measured less than 185 volts, then the compressor partial short circuit is suspected, the camera moved back to the store to try air-conditioning, but also normal. Check the power and found the knife on the power line fixed by long-term use of the screw has been ablated, the pressure is not tight line, causing the ignition is turned on air conditioning. So that the contact resistance increases, power pressure drop, the compressor does not run smoothly, the noise increases. Problem solved after replacing a screw. Coincidentally, the next door neighbor bought a name brand air conditioning, running sound monstrous boot, a neighbor asked me to help look, I used a multimeter amount of the supply voltage is only 172 volts, lower than normal voltage 2182%, determined as a result of The power cord is, smaller diameter caused by the failure of previous years to install. To replace the power cord, all the normal air conditioner power. These two examples illustrate: properly configured for normal use of the power of the air conditioner is very important. In real life, whether rural or urban lines of some of the old house, already thin diameter, and long years of disrepair Xuzhou aging air conditioning maintenance of telephone, electric meter and not enough capacity, simply can not afford such a task; some new houses, due to poor construction quality , line problems and more, there are many hidden aspects of the circuit. Therefore, we should remind you that in determining the fault of the air conditioner, check the power supply. Little things often do more with less. Air conditioning and heating automatically shut down when the air conditioning and heating usually start at the opening mechanism stopped or parked heat just blowing hot air, the red light flashes. Brand machine, air-conditioning more common. US air-conditioning repair air conditioning and heating for the automatic shutdown also lists some of the overhaul of focus: 1, the machine outside the machine heat exchangers and heat sink dirty overload caused by air conditioning; 2, press start capacitance loss, as early as press run overheat protection after a period of time; 3, system problems, such a situation, there are two: ① high and low collusion, only the four-way valve at the micro block ② system, there is a one-way valve and the main sides of the capillary filter Department; 4, press the problem; 5, the temperature sensor.
