The key components involved in commissioning a refrigeration system include the refrigeration equipment itself, such as compressors, condensers, and evaporators, as well as the associated control systems, sensors, and valves. Additionally, the commissioning process involves verifying the correct installation, testing, and operation of these components, as well as ensuring that they are properly integrated and coordinated to achieve optimal system performance. This may also involve reviewing and verifying the system’s design and layout, as well as the specifications and performance of individual components.
