Where does refrigerant absorb heat in a household refrigerator?

It absorbs heat in the evaporator.

  1. Condenser
  2. Compressor
  3. Evaporator ✔

Why: Low-pressure refrigerant vaporizes in the evaporator while absorbing heat from the cold space. The compressor then raises its pressure before the condenser rejects heat outside.

Huh, didn't know that: An expansion device lowers refrigerant pressure before it returns to the evaporator.

The dad joke
The evaporator absorbed the room because it was going through a phase.

    The coolant extracts heat from the refrigerator at the evaporator, causing coolant to vaporize.
