What is the primary function of an evaporator in a refrigeration system?

• A. To compress refrigerant gas
• B. To absorb heat from the environment
• C. To condense refrigerant
• D. To relieve pressure

Answer: (B)

The primary function of an evaporator in a refrigeration system is to absorb heat from the environment. In the operation of a refrigeration cycle, the evaporator facilitates the phase change of refrigerant from a liquid to a gas. As the refrigerant flows through the evaporator coils, it absorbs heat from the surrounding air or liquid, which causes the refrigerant to evaporate. This heat absorption is critical because it cools the surrounding environment, thus providing the desired refrigeration effect. By removing heat, the evaporator plays a vital role in maintaining the overall efficiency and effectiveness of the refrigeration system.
