Air conditioning maintenance tips temperature sensor temperature sensor air conditioner maintenance technique often on the Internet to see some friends on thermal head of post, here are a few tips, you can state you solve this problem in a temperature sensor circuit voltage is 2.5V (25 degrees), the lower the temperature, the higher voltage. 2 because the person's body temperature constant Xuzhou central air conditioning maintenance, so use hand thermal head of a sudden, it's in the circuit voltage is constant (approximately 2.17V) 3 remove temperature head, measuring the resistance of its nest in the road ends, the value obtained is the basic temperature sensor model value, type a value of 4 temperature sensor is its resistance at 25 degrees, usually 5K, 10K central air conditioning, 15K , 20K, 50K. generally negative temperature coefficient. Air conditioning and refrigeration operation panel of the indoor unit wind drops Analysis: If the air conditioner setting the cooling operation, while open wind deflector to swing up and down or run down the deflector angle-modulated long hair. When the ambient temperature is high or the air humidity, the air conditioner indoor air guide plates will produce heat outside cool down the formation of water droplets dripping. Proper use: air conditioning and refrigeration to adjust the angle of the wind deflector blowing horizontal position. After a period of indoor air conditioning and heating cold blow chance this is normal phenomenon for the outdoor unit defrost when defrosting the outdoor unit, indoor chance to stop working, the wind blowing heat temperature around 23 degrees, Xuzhou brand central air conditioning prices, since the original outlet temperature difference is bigger, so the body feels cool breeze blowing, this is normal, you can use it. When the air conditioning and heating outdoor unit outdoor unit does not defrost find air conditioning and heating outdoor unit frosting frosting how many there are major relationship with the outdoor air humidity, in addition to the boot time is longer, the higher the set temperature, the air conditioner reach temperature stop operation will be relatively thick frost (especially been turned on at night, lower night temperatures, higher humidity frost will more) dehumidifying the air conditioner drains undrained this issue should be set up on the problem machine, dehumidifying Air conditioning needs to be set up in 16 degrees, and then select the dehumidification mode, of course, you can also turn on the heating effect of dehumidification, the need to look at the local weather conditions. Air conditioning filter is dirty, how clean? In addition to filters, air conditioning inside the fins also need to be cleaned, but the two slightly different cleaning methods. First you have to prepare a bottle of air conditioning disinfectant, recommended home security, the use of simple, clean and works well. Then turn off the air conditioner, the filter removed, directly on the water wash clean, dry, and then open the home of Xuzhou used central air conditioning recovery, shake a few times, and then the high-pressure nozzle against the air conditioning inside the spray directly over the heat sink , filters and putting it back, start cooling for 15 minutes and air-conditioning on the cleaning is completed, you can go home and try to be cleaned once look good wash after the air conditioning blowing out wind and leaves a faint fragrance of shares. By the way, do not wash too often air conditioning, cleaning air conditioning disinfectant once a month is enough, as long as the water for several minutes each time to get.
