Difficulty: Easy
Correct Answer: True (off-cycle defrost is a valid method)
Explanation:
Concept/Approach
When the compressor is stopped, coil temperature rises above the frost point, allowing accumulated frost to melt (off-cycle defrost), especially in medium/high evaporating temperature systems.
Notes
Other methods include electric heaters and hot-gas defrost for low-temperature (freezer) systems, but stopping the compressor is a standard defrost option in suitable applications.
Final Answer
True
