Detailed Product Description: | Today, then repair a tea shop Galanz air conditioner does not turn on the machine hangs up. Door with a multimeter test have 220V power supply voltage, open the machine housing the test into the motherboard has 220V, pull the plug on again, the motherboard buzzer does not ring, remove the external drive-line, remove the motherboard, view the fuse is good, when the check to board transformer When the wires have been found to have a bite of rat traces, remove the transformer wires are carefully examined mouse really is snapped. To prevent poor contact of the disconnected part connected to the soldering iron and then the electricity is good, wrapped in insulating tape, installed transformer and the motherboard. Electric drip on the machine soon, with the remote boot, outside the machine is working properly. Shell hook installed, commissioning three minutes Xuzhou hand air conditioning repair parts, heating, air conditioning repair used in Xuzhou good customer satisfaction. Maintenance Summary: Most hotels, restaurants, bakeries and other food and beverage industry in Xuzhou used central air conditioning recovery, rodent more hair, more service please note the wires connecting the electronic parts is good. Power does not turn on the air conditioning machines common in the following situations: First, the power supply problem, no power or voltage is not normal. Second, the board or motherboard bad transformer cable disconnected. Third, the remote control or a bad motherboard. To check the specific situation step by step. Three central air conditioning system facing hazard 1, harms - fouling fouling effect on the cooling effect can refer to Table 1. Table 1 shows the average thermal conductivity of the scale does not exceed 0.5-0.6 kcal / (m · h · ℃), only 0.15% copper, both of which were very different. Scale will affect heat transfer, which will bring two problems: First, reduce the cooling effect. Film coefficient of heat transfer inside and outside on both sides of refrigerator condenser tubes are large hand air conditioning, so the impact of fouling resistance due to the scale of the overall heat transfer coefficient is particularly significant, the heat transfer performance. Figure 1 is a scale layer thickness (mm) and decrease the amount of energy consumption (%) relationship, Figure 2 is a dirt layer thickness (mm) and the total increase or decrease in unit cooling capacity (%) relationship. The figure shows, each 0.1 mm thick scale cooling capacity will be reduced by about 14%; secondly, condenser pressure will rise, leading to increased load, but consume more energy. 1 mm scale will consume energy 20-30%, high pressure will cause central air conditioner serious accident shut down the scale. Xuzhou brand used air conditioning prices, Sheng Erda refrigeration (certified), second-hand air conditioning provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
