What is the heat gained per pound of refrigerant in the evaporator called?

The term for the heat gained per pound of refrigerant in the evaporator is known as the refrigerating effect. This terminology refers specifically to the cooling capacity of the refrigerant, which is absorbed in the evaporator as it changes from a liquid state to a vapor state. During this phase change, the refrigerant absorbs heat from the surrounding environment, which is the fundamental process that enables refrigeration systems to create a cooling effect.

Understanding this concept is critical for those working with refrigeration systems, as it directly relates to efficiency and performance. The refrigerating effect is crucial for calculating the capacity of a refrigeration system and helps in determining how effectively a refrigerant can absorb heat. This knowledge is essential for selecting the right refrigerant and designing systems that meet specific cooling requirements.
