The heat absorbed after the refrigerant has vaporized becomes _____?

The heat absorbed after the refrigerant has vaporized becomes superheated. In the refrigeration cycle, when a refrigerant is vaporized, it initially exists as a saturated vapor, having absorbed heat at its boiling point. However, once additional heat is added beyond this point, the temperature of the vapor increases further, resulting in a state known as superheated vapor.

Superheating is important because it ensures that the refrigerant remains in a completely vapor state as it moves towards the compressor. If the refrigerant enters the compressor as a mixture of liquid and vapor, it can cause damage to the compressor. Therefore, the process of absorbing heat after vaporization raises the refrigerant's temperature above its saturation point, which characterizes it as superheated. This plays a crucial role in maintaining efficiency and preventing mechanical issues in the HVAC system.
