One of the most common applications of ammonia refrigeration systems is to produce and maintain space temperatures by circulating air through a refrigerated coil. If the temperature of the ammonia in the coil is below 32ºF (0ºC), water in the air freezes and accumulates on the coil. The ice blocks airflow and acts as an insulator, penalizing coil performance. For efficient performance, the coil must be defrosted periodically. The defrost cycle is a necessary and important part of the design of the refrigeration system.
