Which component is responsible for converting the refrigerant from a gas to a liquid?

The condenser coil is responsible for converting the refrigerant from a gas to a liquid. When refrigerant vapor enters the condenser coil, it is subjected to a cooling process, typically through the air or water flowing around the coil. As the refrigerant releases heat to the surroundings, it undergoes a phase change due to a drop in temperature and pressure, transitioning from a gaseous state back to a liquid. This process is essential in the refrigeration cycle because it allows the refrigerant to be reused effectively in continuous cycles of heat absorption and release.

In contrast, other components play different roles in the refrigeration cycle. The evaporator coil is where the refrigerant absorbs heat and evaporates into a gas. The expansion valve regulates the flow of refrigerant into the evaporator coil, allowing it to expand and lower its pressure before it evaporates. The compressor, on the other hand, compresses the refrigerant gas, raising its pressure and temperature before it enters the condenser. Each component has a distinct and crucial function, but it is the condenser coil that specifically facilitates the conversion of refrigerant from gas to liquid.
