What is one important reason for using both synchronous motors and induction motors in a refrigeration plant?

Using both synchronous motors and induction motors in a refrigeration plant is essential for correcting the overall power factor. Synchronous motors can be designed to operate at leading power factors, which means they can counteract the lagging power factor typically associated with induction motors. By incorporating synchronous motors, a refrigeration plant can improve its overall power factor, which is crucial for reducing energy losses, avoiding potential penalties from utility companies, and enhancing the overall efficiency of the electrical system.

In many industrial settings, a poor power factor can lead to increased current draw from the electrical supply, resulting in higher energy costs. By implementing synchronous motors alongside induction motors, facilities can achieve a more balanced power factor, contributing to energy efficiency and operational cost savings. This capability to improve power factor correction is significant in applications like refrigeration plants, where large motors are frequently in operation.
