What does 'Cv' stand for in refrigeration terminology?

In refrigeration terminology, 'Cv' stands for the Coefficient of flow. This term is significant as it quantifies the flow capacity of a valve or fitting in a refrigeration system. The Cv value indicates how much fluid can pass through a valve at a specified pressure drop, which is crucial for system design and efficiency. A higher Cv means the valve allows a larger flow rate, which can affect the overall performance of the refrigeration system.

Understanding the Cv is essential for operators when selecting valves, as it influences the sizing and the energy efficiency of the refrigeration system. Other terminologies mentioned, such as coefficient of variation, coefficient of volume, and coefficient of velocity, do not accurately describe this specific context within refrigeration. The focus is on flow capacity, making the Coefficient of flow the correct interpretation of 'Cv' in this field.
