Compressor common failure is not running and no major calls, there is no running sounds, noise, small displacement (1) Xuzhou conditioning maintenance, no running and no buzzing sounds cause of the failure is caused by internal motor windings open, by measuring with a multimeter power block housing between terminals overcast value to determine if the resistance is infinite or too large, indicating winding open (2), not running but buzzing bass sounds that caused the failure of reason The main motor winding short circuit or mechanical system in the card cylinder, not only buzzing sounds when the axle failure, winding short-circuit, and the shell temperature of the compressor is high in a short time, not to overload will cause the action, For this fault, with a multimeter power block resistance measured between terminals, if resistance is lower than the resistance of the resistance and CR CS ends at both ends of the normal or less than the resistance across RS, indicating that the compressor motor windings Xuzhou shorted Oaks air conditioning sales, and measuring the compressor currents greater than normal, while the mechanical system in the card cylinder, when axle failure, the motor winding resistance is normal. LG air-conditioning, some compressors built-in thermal protection, when the compressor overheating, over-temperature protection device is turned off, then if the measure resistance between the compressor is infinite, so when you want to measure the motor winding resistance Then the temperature dropped to sub-ambient temperature after the same, otherwise beginners may misjudge the compressor motor windings open. Methods and techniques of suspected card when the compressor cylinder, direct tapping with a hammer after the shutdown of the compressor housing, electricity and air conditioners for the United States, if the compressor is able to operate normally, indicating that the card cylinder troubleshooting, adding some frozen lubricants can continue to use, if percussion invalid, the first compressor lubricant filling some frozen, and then test to see whether the operation, if the operation, indicating a fault caused due to lack of refrigeration lubricants, air conditioning repair, if still can not run, you need to replace the compressor. Central air-conditioning energy saving control air conditioning unit is a smart way to building the most energy-consuming devices running their different ways, the following aspects should be considered energy-saving air-conditioning units: 1. annual operating system condition automatically converted according to outdoor weather conditions and air conditioning systems the different requirements of different structures and processes of the conversion conditions were small, generally baked value judgments as the conversion conditions by adjusting the air conditioning operating parameters to achieve. 2. Select a reasonable choice of PID controller parameters parameters of each loop, so that it has a good response performance, or choose from a variety of advanced control algorithms, the control system to improve performance. Avoid total control loop is constantly adjusted or adverse effects, such as slow response process Xuzhou air conditioning repair and installation, a waste of energy but also affect the life of the actuator. 3. Multi-level effective control of some systems with a central air conditioning unit outside the room with a reheat coil (especially the air conditioning process) to achieve individually adjustable. In this case, a reasonable choice of control method and with the relationship between supply air temperature control, to prevent the central air supply temperature is too low, resulting in a waste of energy reheating room phenomenon. 4. Use high-quality indoor air temperature sensor is adjusted every 1 ℃ difference consumes a lot of energy, high-precision sensor selection, energy efficiency is much greater than the price of the sensor. 5. should automatically adjust the temperature setting with the outdoor temperature for comfort air conditioning systems, can be increased in the summer with the outdoor temperature, an appropriate increase in the setpoint temperature, reducing indoor and outdoor temperature difference, both guarantors of comfort requirements, but also to achieve energy savings. Winter is also suitable for similar control.
