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.

Summary of the key issues of the servo motor drive

According to the current of the motor, use a driver that is greater than or equal to this current. If low vibration or high precision is required, a subdivision drive can be used. For high-torque motors, use high-voltage drivers as much as possible to obtain good high-speed performance.
