What occurs in an evaporator of a refrigeration system?

• A. Absorbs latent heat
• B. Condenses
• C. Compresses
• D. Releases sensible heat

Answer: (A)

In the evaporator, the refrigerant is at low pressure and begins to absorb heat from the space being cooled. This heat absorption causes the refrigerant to change from liquid to vapor, which is a transition that requires latent heat. As a result, heat is drawn from the surroundings, cooling the space. The evaporator’s job is not to condense, compress, or release heat—that happens in the condenser, compressor, and related processes, respectively.
