Xuzhou Sheng Erda Refrigeration Electrical Services Ltd compressor does not run Cause 1: Power Troubleshooting: with a multimeter, electric pen then check the troubleshooting items. Replace bad fuse fuse, wire break is rewiring Reason 2: Power supply voltage is too low voltage values ??measured with a multimeter to exclude, if necessary, by the power regulator device with three reasons: loose wire connection or disconnection of exclusion: Check the wire joints, loose off the connector should be re-inserted firmly seated, by professional maintenance Xuzhou Sheng Erda Refrigeration Electrical Services Limited ☆ auxiliary heating in the cold and warm air conditioner indoor unit increase in certain power electric heating pipe, when the air conditioner In the outdoor temperature is low conduct heat pump system running old air-conditioning, heating capacity is usually relatively low, and by electric heat pipe heat to make up for its lack of a certain old Xuzhou Gree, which can increase the overall heating capacity. ☆ bigger bridge caulking caulking Fin Fin technology bridge fin heat exchanger is to punch a convex shape of the bridge Xuzhou old central air conditioning, the fin and the flow of air in contact area is conducive wings sheet is heat-exchanged with air, compared, it is easier for heat exchange than the finned plate, greatly improve the efficiency of the heat exchanger. ☆ hydrophilic treatment hydrophilic treatment is in the traditional aluminum foil coated with a hydrophilic membrane processes. Fin evaporator surface is hydrophilic treatment, easy to make the condensate flow, reduce air flow resistance between the evaporator, making it easier for air to flow through, in order to improve the heat transfer efficiency. Evaporator without hydrophilic treatment, easy to plug the air, reduce the heat exchange efficiency, and increased noise. Xuzhou transfer old air-conditioning, refrigeration Sheng Erda (certified), old air-conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
