Refrigerators, I believe that every household has its figure, which guarantees the freshness of the food and brings a hint of coolness on the hot summer day. The core component of the refrigerator is the compressor. How does the refrigerator compressor work? Today, let's take a look at the relevant introduction of refrigerator compressor!

The core component of the refrigerator is the compressor. How does the refrigerator compressor work? Today, let's take a look at the relevant introduction of refrigerator compressor! Working principle of impedance split-phase starting refrigerator compressor
The stator winding of the compressor motor is an inductive coil. Since the wire diameter and the number of turns of the running winding and the starting winding are different, the impedance is also different. When the two windings are connected to the AC circuit, the current in the running winding lags the voltage by 90° to produce two different inductance values, although the same phase 50Hz alternating current is reached on the two windings, and on the two windings The current and voltage values that produce different phase differences play the role of resistance phase separation and generate starting torque. When the motor speed reaches 70%~80% of the rated speed, the start winding is disconnected from the start winding circuit under the control of the start relay, and only the running winding drives the motor to run. Refrigerator compressor brand
. Embraco Compressor: Embraco is the world's largest compressor manufacturer, from Brazil, with a 25% market share of global compressors. At present, most domestic refrigerators use compressors manufactured by Beijing Embraco Snowflake Compressor Co., Ltd., a joint venture in China, and a few high-end models use imported Embraco compressors. 2. Panasonic Compressor: Panasonic also has a strong strength in compressors. At present, the most common domestic refrigerator compressors produced by Wuxi Panasonic or Singapore Panasonic are generally not indicated as original imported compressors. They are all Wuxi Panasonic products. Some refrigerator products from manufacturers like Siemens will also use Panasonic compressors. 3.Zanussi Compressor: Zanusi Company originally belonged to Electrolux Group, the world's largest white goods enterprise, and sold it to ACC of Italy when Electrolux adjusted in 2003. At present, the compressor products are mainly produced by its joint venture company in Tianjin, which is used for domestic refrigerators. Refrigerator compressor repair 1. After the power is turned on, use a wooden hammer or rubber hammer to lightly knock on the casing of the compressor, and continuously change the knocking position. This method can eliminate the slight jamming and holding faults. 2. For inverter compressors, you can use a voltage regulator to increase the power supply voltage properly, or connect a non-polar electrolytic capacitor in series in the compressor's starting circuit as the starting capacitor to increase the starting current of the compressor to eliminate minor cards. Cylinder, hold the fault. 3. For serious seizures and stuck cylinders, a new compressor should be replaced.
I have introduced this to the refrigerator compressor. I hope it will be helpful to you. For more information on refrigeration information, please visit okmarts.com, so stay tuned
