During the defrost cycle of a refrigeration system, what is primarily being removed?

The primary focus during the defrost cycle of a refrigeration system is to eliminate ice buildup on the evaporator coil. When the temperature of the evaporator coil drops below freezing, moisture in the air can condense and freeze on the coil, creating ice that obstructs airflow and reduces the efficiency of the system.

The defrost cycle activates heating elements or reroutes refrigerant to warm the coils, causing the ice to melt and drain away. This process is essential to restore airflow and maintain efficient operation of the refrigeration system.

While factors such as heat from the refrigerant and excess moisture in the air do play a role in the overall function of the refrigeration system, the primary goal during the defrost cycle is specifically targeted at addressing the ice accumulation on the evaporator coil.
