There are really many kinds of air-conditioning compressor patterns revealed

Air-conditioning compressors have always been dubbed the "heart" of air-conditioning by industry insiders, but many small partners do not understand the important object of air-conditioning, and they are also very curious. What does the air-conditioning compressor look like? How are they different? Today, I will briefly explain to the friends the different classifications of air-conditioning compressors

Water-Cooled Chiller vs Air-Cooled Chiller: Which One is Better?

When it comes to cooling systems for large commercial buildings or industrial facilities, two of the most common options are water-cooled chillers and air-cooled chillers. Both types of chillers are designed to remove heat from a building or industrial process, but they operate in different ways and have their own unique advantages and disadvantages.

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.
