What is the correct procedure to start a centrifugal chiller?

The correct procedure to start a centrifugal chiller involves a systematic approach to ensure efficiency and safety, which is reflected in the selected choice. Starting with the chilled water pump ensures that the system has the necessary flow of coolant before engaging the compressor. This helps to prevent potential issues such as compressor overheating or damage due to lack of sufficient cooling fluid.

Following this, starting the condenser water pump is crucial because it circulates the water that helps to remove heat from the chiller system, promoting optimal operation. Checking the oil is also an important step as it ensures that the compressor is adequately lubricated, reducing wear and tear. Starting the cooling tower last is appropriate because it supports the overall thermal management of the system by facilitating heat exchange.

This sequence is designed to establish a reliable flow of water and proper lubrication before the chiller begins to operate under load, ensuring reliable functionality and protecting the integrity of the equipment throughout its operational life.
