In the evaporator, the refrigerant plays a crucial role in the refrigeration cycle by absorbing heat from the surrounding environment. As the refrigerant enters the evaporator in a low-pressure liquid state, it absorbs heat from the air or water that it is cooling. This heat absorption causes the refrigerant to change state from liquid to gas, effectively evaporating. This process allows the refrigerant to carry away heat, thus cooling the environment it is in contact with.

This principle is fundamental to how refrigeration systems work, as the ability of the refrigerant to absorb heat and evaporate directly impacts the efficiency and effectiveness of the cooling process. The phase change from liquid to gas is accompanied by a significant absorption of energy, which is why this part of the cycle is essential for achieving the desired cooling effect.
