Commissioning refrigeration systems ensures safety by verifying that the system is designed and installed in accordance with applicable regulations, codes, and standards. This includes ensuring that the system is properly sized, installed, and configured to prevent hazards such as refrigerant leaks, electrical shock, and mechanical failure. Commissioning also verifies that safety devices, such as pressure relief valves and emergency stops, are functioning correctly. By ensuring that the system is safe to operate, commissioning helps to protect people, property, and the environment.
