Rgb (255,255,255); "> air conditioning repair service, we have excellent technology, high sense of responsibility and reasonable prices in the industry come to the fore, Xuzhou City, air conditioning maintenance services industry has set a pioneering example of quality air conditioning and heating in winter, the outdoor unit heat exchanger temperature is very low, it will have after the frost phenomenon encounter with ambient air, frosting is too thick, it will affect the efficiency of air conditioning, So air conditioning will automatically defrost treatment. defrost switch is actually a four-way valve to change the direction of flow of freon (air conditioning cooling state but in the indoor unit fan is not working, otherwise blowing cold air), so that the outdoor unit heat exchanger will bear frost to melt away Xuzhou central air conditioning repair, time is about 2-3 minutes winter air does not defrost reasons: 1, ambient temperature is too low not defrost: Winter ambient temperature is too low, resulting in air conditioning, then defrost difficulties, due to Outdoor temperatures below 0 degrees Xuzhou air conditioning maintenance and fluoride, affecting the air conditioning and heating effect, the lower the outdoor temperature, the worse the effect of air conditioning and heating, which is actually not enough heating capacity 2, air conditioning and heat enough not defrost: air conditioning heating is normal, but for an area smaller than the use of air conditioning and heating, air-conditioned room area, such as the machine with 50 (2), and using 35 machines (1.5) at room temperature, of course do not, that is not enough Rated heating capacity There are also auxiliary heating may not be open, at least part of the heating capacity of 3, the air conditioning filter is clogged: air conditioning and heating normal, but for a long time due to indoor air conditioner filter does not remove dust, resulting in clogged with dust filters, resulting in reducing the amount of circulating air. causing heat blowing enough, can not defrost. 4, the system leads to lack of fluoride defrost heat is not enough, and thus can not defrost. 5, the control board failure, air conditioning did not defrost. 6, defrost temperature sensor failure, resulting in air conditioning no frost. Clean air conditioning heat sink away from the respiratory apricot weather, many people have begun to use from the air conditioning, but respiratory outpatient reporter recently learned from the major hospitals, because patients with respiratory tract infections caused by air conditioning began to increase. [public Wu Miss (voice) uncomfortable for some time after one week they began to hurt] data show that Xuzhou air conditioning repair parts, air conditioning, heat sink significantly higher bacterial and fungal contamination of the filter, so people must develop regularly cleaned and disinfected air conditioning habits, must be cleaned and disinfected before the season turned conditioning heat sink. [air conditioning maintenance personnel in the use of air conditioning and process should be done once every two months disinfection] In addition, the heat sink cleaned, filters also help save energy and prolong conditioning life.
