Pay attention to these details. The air energy heat pump can be used for more than 10 years.

In a few months, the northern heating season will officially begin. In addition to central heating, this year's "coal-to-electricity conversion" has also received much attention.

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.

The role of refrigerant in the air-cooled chiller

The refrigerant itself circulates continuously in the refrigeration system, and then realizes refrigeration through its own state changes. The refrigerant absorbs the heat of the cooling medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense.
