What does excess cost per hour for running poorly refer to?

The term "excess cost per hour for running poorly" specifically refers to the increased operational cost that results from inefficiencies in the refrigeration system. When a system is not operating at optimal levels, it may consume more energy, require additional maintenance, or incur higher labor costs to compensate for its poor performance. These inefficiencies contribute to higher overall operating expenses, meaning that the cost of running the system exceeds what it should be under normal, efficient operating conditions.

Understanding this concept is vital for industrial refrigeration operators, as it highlights the importance of maintaining systems properly, optimizing performance, and addressing issues promptly to minimize costs associated with inefficiency. This knowledge can lead to better decision-making in operations and maintenance practices, ultimately enhancing the system's overall performance and reducing unnecessary expenditures.
