Detailed Product Description: | On refrigeration engineering of refrigeration oil: 1, compressor lubricants in refrigeration engineering usually called frozen oil, which plays an important role in the operation of the refrigeration compressor. Under normal circumstances, oil change air-conditioning unit is factory run a cooling season (or heating season) to replace the oil once and then replaced periodically depending on the operating conditions. Because the unit during the assembly process, in order to prevent further leakage, use of welding methods, welding nitrogen welding process, but the filling of the nitrogen pressure is not big, big welding tainted point, that in the presence of air The case of welding, there are a lot of scale exist in the system, such as the scale of the refrigerant in the system operation, can hinder the transportation of oil from the minute the compressor rotor wear, and may block the oil supply capillary causing the unloading system failure, resulting in the unit normal operation can not be stable; 2, refrigeration compressor with lubricating oil during operation, lower compressor temperature, compressor seal the gap between acting parts and provide add, subtract load function, Therefore, the kinematic viscosity refrigeration oil, small amounts of moisture, copper corrosion, acid number and insoluble material must meet the standards. Through years of detection test Xuzhou brand used air conditioning prices, summarized need to be replaced once a year to run, short run time in the north, can be changed every two years; air-conditioning filter is dirty, how clean? In addition to filters, air conditioning inside the fins also need to be cleaned, but the two slightly different cleaning methods. First you have to prepare a bottle of air conditioning disinfectant, recommended home security, the use of simple, clean and works well. Then turn off the air conditioner, the filter removed, directly on the water wash clean, dry, and then open the home security, shake a few second-hand wedding dresses in Xuzhou, air conditioning and high-pressure nozzle toward the inside of the heat sink sprayed directly again , filters and putting it back, start cooling for 15 minutes and air-conditioning on the cleaning is completed, you can go home and try to be cleaned once look good wash after the air conditioning blowing out wind and leaves a faint fragrance of shares. By the way, do not wash too often air conditioning, cleaning air conditioning disinfectant once a month is enough, as long as the water for several minutes each time to get. Air conditioning maintenance tips temperature sensor temperature sensor air conditioner maintenance technique often on the Internet to see some friends on thermal head of post, here are a few tips, you can state you solve this problem in a temperature sensor circuit voltage is 2.5V (25 degrees), the lower the temperature, the higher voltage. 2 because the person's body temperature constant, the temperature sensor with the holding of a sudden, it's in the circuit voltage is constant (approximately 2.17V) 3 to remove the thermal head hand air conditioning, measured at both ends of the transposon road resistance Xuzhou used central air conditioning recovery, the value of the resulting model is the basic sense of the value of the head temperature, type a value of 4 temperature sensor is its resistance at 25 degrees, usually 5K, 10K, 15K, 20K, 50K. generally negative temperature coefficient. Xuzhou used central air conditioning recovery, Sheng Erda refrigeration, air conditioning used by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou used central air conditioning recovery, Sheng Erda refrigeration, air-conditioning is used Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Liu Wanhai. |
