What rejects the heat absorbed by the evaporator and compressor?

Explanation:
In a refrigeration cycle, the component that must get rid of the heat taken in by the evaporator (and the extra heat from the compressor) is the condenser. The evaporator is where heat is absorbed from the cooled space, and the expansion device only lowers pressure to enable evaporation. The condenser then rejects that heat to the surroundings, allowing the refrigerant to condense back into a liquid and continue the cycle. The king valve is simply a control valve and does not reject heat.
