Evaporator terminology — common names used in refrigeration Which of the following alternative names correctly refer to the evaporator component in a vapor-compression refrigeration system?

Introduction / Context:
The evaporator is the low-pressure heat absorber where liquid refrigerant boils and removes heat from the conditioned medium. In practice, different industries use varied names for the same component based on application temperature.

Given Data / Assumptions:

• The component is the evaporator in a vapor-compression system.
• Applications range from comfort cooling to freezing.

Concept / Approach:
When the evaporator is used for comfort or process cooling above 0°C, it is commonly called a cooling coil or chilling coil. In low-temperature applications (freezers, cold rooms), the same heat-absorbing coil is often termed a freezing coil. All refer to the evaporator function: absorbing heat as refrigerant evaporates.

Step-by-Step Solution:

Verification / Alternative check:
Manufacturer catalogs and site terminology label fin-and-tube or plate heat exchangers as cooling/chilling/freezing coils depending on duty, all connected to the suction line.

Why Other Options Are Wrong:
“Superheating coil only” is not a standard component name; superheat is a condition often achieved in the evaporator outlet region, not a separate coil in typical systems.

Common Pitfalls:
Assuming different names imply different thermodynamic components. They describe the same evaporator used at different temperature levels.

Final Answer:

all of these
