What does the coefficient of performance (COP) indicate?

The coefficient of performance (COP) is a key indicator of the efficiency of a refrigeration system. It is a measure of the ratio of useful heating or cooling provided to the work required to produce that heat or cooling. A higher COP value signifies a more efficient system, allowing it to generate a greater amount of cooling or heating per unit of energy consumed. This makes the COP a crucial parameter for evaluating how effectively a refrigeration system operates. Understanding and calculating the COP can help technicians assess equipment performance and utility costs over time, leading to better service and maintenance decisions.
