The role of coils in the refrigeration cycle
Coils are known as the most important component in air conditioning and refrigeration systems. One of the most important heating and cooling cycles is the refrigeration cycle. Condenser coils, usually located in the outdoor unit of the system, help to dissipate the heat that has been absorbed from the indoor space. These coils operate at high pressure and temperatures and help to convert the refrigerant from gas to liquid. On the other hand, the evaporator coils, which are located inside the space, absorb the heat load from this space and cause the refrigerant to evaporate which makes the desired space to cool. The design and materials of coils are varied, and options such as copper and aluminum are common due to their excellent thermal conductivity. Fin tube coils are common and used in both types of condenser and evaporator coils due to their efficiency and excellent design. The choice of coil type depends on the system requirements (project area, climate, functional purpose, etc.), financial constraints, and desired performance characteristics.
