Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, and in particular to an electrical control box for a variable frequency air suspension centrifuge unit. Background Technology

[0002] Due to its advantages such as high efficiency, energy saving and low noise, air-suspension variable frequency centrifugal chiller units have gradually become the mainstream choice in the market. As the main control unit of the unit, the electrical control box plays a crucial role. By integrating multiple functions such as electrical control, power management and signal processing, it provides an efficient and reliable control solution for electromechanical equipment. Therefore, an electrical control box for variable frequency air-suspension centrifugal chiller units is used.

[0003] Traditional unit electrical control boxes generally only contain the main control unit. Air-suspended variable frequency centrifugal chiller units also include a driver and a cooling fan to ensure the normal operation of the driver. Usually, a separate drive box is required, which shows certain limitations in terms of integration, intelligence level, maintenance and upgrades. In use, it is inconvenient to splice and does not save assembly time effectively, resulting in low applicability. Utility Model Content
