What state does the refrigerant enter after passing through the evaporator?

After passing through the evaporator, the refrigerant enters a gaseous state. This process occurs because the primary function of the evaporator is to absorb heat from the surrounding environment, which causes the refrigerant to evaporate. As the refrigerant absorbs heat, it changes from a liquid to a gas, effectively removing heat from the space being cooled. This heat absorption is crucial for the refrigeration cycle, as it allows for the cooling effect needed in refrigeration systems.

Understanding this process is fundamental in refrigeration, as it showcases the role of evaporators in converting low-temperature and low-pressure liquid refrigerant into low-temperature and low-pressure gas. In contrast, the other states listed—liquid, solid, and mist—do not accurately describe the state of refrigerant after it has completed its heat absorption function in the evaporator.
