Teach you how to diagnose air conditioning is not the lack of fluoride air conditioning freon refrigeration and heat are needed to help, so once the lack of freon air conditioning, air conditioning will be a series of reactions, such as the cooling effect decreased significantly. Serious or even air conditioning compressor does not start automatically protected. So the lack of fluoride for an air conditioner is a very serious problem, here are a few ways to judge conditioning lack of fluoride. 1. The low-pressure pipe (crude pipe) dry, touch, and feel there is no ice. This is because of the lack of freon, the evaporator which reduces the boiling point of the refrigerant, the refrigerant temperature of the low-pressure pipe in the valve increases. 2. The high-pressure pipe frosting. The reason is that the pressure drop within the tube, a lower boiling point, the high pressure pipe temperature is below freezing, the air in the water turns into ice. 3. Turn on the machine panel, remove the filter, naturally you can see above the evaporator frost. If frosting is less area is small, indicating lack of refrigerant resulting in reduced cooling capacity. The outdoor unit without thermal exhaust. The reason is lack of the refrigerant, resulting in condensing pressure and temperature decrease. 5. The machine drains, water less or not at all, no water. This is because the lack of fluoride leads to decreased cooling capacity, the condenser can not condensate. 6. From the outdoor unit charge fluoride mouth measured pressure is lower than 0.45MPa. The reason is that the refrigerant shortage, leading to the evaporation pressure drops. If only the low-pressure gas pipe valve frost, proved to be only a trace amount of lack of fluoride, the ambient temperature is too low; two valves are frost, indicating the system has secondary throttle phenomenon. Air conditioning unit bracket "extended" professional, said five or six years to replace a "Huaiyin area until after Ash Street Road around the old air conditioning unit residential decorative fence severe corrosion, partly broken off, there are security risks . "Recently, the public Liu told this newspaper reflect their own air conditioning residential fence security risk. For these fence, reporters learned that the relevant departments are working gradually dismantled. However, there are still a lot of old residential air conditioner bracket security risk, it also requires the people themselves to check and replace. "I lived in Ash Street, here's residential construction are quite a long time, most of them are old tenants, decorative fence here, the air conditioning unit is installed when the Games, most of all there rust phenomenon, generally only concerned with air conditioning can not be used, who will focus on the outside of the rack ah! "Liu told reporters that he usually does not pay attention to the day when he was watering the flowers, accidentally ran into the railing, and fell a big Block rust, startling him. At this time, Mr. Liu realized that there are security risks. According to reporter observed, these rusty iron railings in residential building facades Xuzhou central air conditioning repair, the whole building without cover Xuzhou air conditioning repair, air conditioning unit in case of fall, will fall directly upstairs to the road, it is likely hit passers. Reporters visited found that in addition to Ash Street in neighboring Lee reflected by the Road along Alexander Road, near Lake Road and Zi Qian road, there are many old district exist "rusty" situation. The provincial capital of air conditioning brackets are used for what material? "Lifetime" How long? Reporter consulted Xuzhou Mr. Fu Sheng Erda air conditioning repair company, according to Mr. Fu introduction, the provincial capital of air conditioning bracket mostly triangle-based, general bearing in about 40 kg, in 2056 to be replaced once the bracket. Central air conditioning repair: How to clean up promptly for air conditioning in the season, eventually becoming a bath cleaning hazards: the evaporator and condenser air conditioner outdoor unit indoor dust mask is full of Xuzhou conditioning maintenance calls, it will affect the air conditioning and heat distribution, resulting in air conditioning cooling or heating effect weakened, when electricity costs; when the air conditioning is turned on, the bacteria inside the air-conditioning will be blown directly into the indoor air, causing direct harm to the human body. Many families in the summer after the last stop using air conditioning, clean air-conditioning will be ignored, so the air conditioning vacuum adsorption of a large number of online dust, mites, pollen, and mold began wantonly lice multiply. Second year again when the air-conditioning, these germs, viruses, fungi and dust was blowing out air conditioning, often triggered massive respiratory infections and atopic dermatitis. Cleaning methods: Therefore, the use of air conditioning is generally before the summer or autumn after use in need of a cleaning and maintenance. To thoroughly to kill bacteria in the air conditioning, the best professional mechanic cleaned once a special cleaning fluid with air conditioning. Central air conditioning maintenance tips: cleaning of air conditioning directly affect the health of their families, the so-called air-conditioning disease also causes related to Xuzhou cleaning and air conditioning air conditioning maintenance Phone | Air Conditioning | Cooling by Xuzhou Sheng Erda 圣尔达 Refrigeration Electrical Services.
