The purpose of a defrost cycle in a refrigeration system is to?

The purpose of a defrost cycle in a refrigeration system primarily focuses on removing ice build-up on the evaporator coil. During normal operation, moisture in the air can condense on the cold evaporator coil and freeze, especially in low-temperature applications such as commercial refrigeration. This ice accumulation can hinder heat exchange efficiency, leading to reduced cooling performance and possibly damaging the system.

The defrost cycle temporarily halts the cooling process and applies heat either through the use of electric heaters or by reversing the refrigeration cycle, which helps to melt the ice and restore efficient operation. By regularly removing this ice, the system can maintain optimal airflow and functionality, ensuring that it runs effectively without extra strain on the components. This process is vital for the longevity and efficiency of the refrigeration unit.
