Select the cooling capacity of the principles are: air conditioner cooling capacity should be slightly larger than the cooling load of the room, the heat load of the room should be taken into a room facing the walls and roof insulation, air conditioning repair the situation, as well as an indoor heat source, including the number of personnel. Example: a 16 m2 bedroom or living room, with a much needed cooling capacity of the air conditioner? Common room cooling load recommended value 115-145W / m2, taking the middle value 130 W / m2 basis for calculation, the cooling load = 130 × 16 = 2080W. Since the actual air conditioner refrigerant than the nominal value of the lower 8%, so the name of the selected air conditioner cooling capacity must be greater than 2080 ÷ 0.92 = 2260W. Selection of nominal cooling capacity of the air conditioner should be about 2300 W. For air-conditioning effect demanding room cooling load should take 160-180 W / m2. Here mention about watts (W) in the past with a cooling capacity of the unit kcal / hour relationship (kcal / h) between: 1W = 0.86kcal / h; 1kcal = 1.16W. Japanese power conditioning repair is commonly used compressors (horsepower) to represent the value of cooling capacity, it is the habit of the past, is not exact, because the coefficient of performance of the plant and the product of each period is different, but generally horsepower and cooling capacity the following relationship: 0.5 unit cooling capacity 1600-2000W 0.75 匹 unit cooling capacity 1800-2400W 1 匹 unit cooling capacity 2200-2800W 1.5 匹 unit cooling capacity 3200-4000W 2 匹 unit cooling capacity 4000-5000W Still need air conditioning when windows? Due to the frequent use of air conditioning in summer, the air conditioning disease occurrence rate has gradually increased, so the air conditioning when windows is it beneficial? Today, Sheng Erda conditioning repair on this phenomenon to answer your questions: the temperature began to rise, many families will be open air for a long time to cool, in fact, air pollution also, but the child's injury is very big too! Many parents covet cool, long open air, but air conditioning may ignore the harm to the child's health. This summer is the "Air conditioning disease" high incidence of children, especially infants and young children due to poor stability of the immune system, weak resistance, long stay in air-conditioned rooms, more susceptible to "Air conditioning disease." Children conditioning disease is not just due to the simple indoor and outdoor temperature difference caused by household air conditioner fins secondary pollution caused by air conditioning repair parts Xuzhou, direct stimulation of the respiratory system, central air Xuzhou high-profile child maintenance, but also induce children "Air conditioning disease" important reasons. During the summer, children usually have a longer period of time compared to being in such a closed indoor air secondary pollution, resulting in children summer "Children conditioning disease" increased significantly. Many families tend to clean air filter, but can not reach a thorough disinfection purposes. Hidden behind the filter as hot and cold air conditioning heat sink exchange must pass through, the air of dust, dirt accumulate, plus air conditioning condensation caused by wet conditions and suitable temperature Xuzhou air conditioning maintenance and installation, easily lead to bacteria blooms in the heat sink, causing air conditioning pollution. The survey found that the total number of bacteria on home air conditioning heat sink up to 160,000 per centimeter squared! Compared with the filter, heat sink more filth. Air conditioning pollution hand may cause dermatitis, eczema, fungal infections and other skin diseases, on the other hand may also lead to asthma, rhinitis and other respiratory diseases. Therefore, to prevent contamination have the right to clean air conditioning awareness, clean the filter, the more you want to buy with the "Ministry of Health disinfection product license number" for dedicated air disinfectant corresponding models for air conditioning heat sink for regular cleaning and disinfection . Remind you that in the use of air conditioning, do not forget to always open the window for ventilation, which is to improve the indoor air quality of the most simple and effective way.
