What occurs within a refrigeration system when refrigerant undergoes a phase change in the evaporator?

💡 Explanation

When refrigerant changes phase from liquid to gas in the evaporator it absorbs thermal energy as latent heat because energy is needed to overcome intermolecular forces rather than raising temperature, thus cooling the surrounding the space. Therefore latent heat absorption cools the space, rather than overheating, icing, or pressure increases under regular functioning.
