Decreased defrosting operation time and extended heating operation time by control depending
on amount of frost
The amount of frost can be estimated from the length of last defrosting. If the amount of frost is less than the last time,
then heating operation until next defrosting operation is extended automatically. As a result, unnecessary defrosting
operation is avoided, increasing availability of continuous heating operation.
