• The operation diagram is as following.

Deice Control

• Deicing operation is controlled by timer and sensing the indoor pipe temperature.
• Temperature difference ,1 T1 of the indoor pipe temperature and the indoor intake air temperature are checked after 25 minutes passed starting of heating operation.(,1 T1)
• Temperature difference ,1 T2 of the indoor pipe temperature and the indoor intake air temperature are checked after 60 minutes passed starting of heating operation.(,1 T2)
• Deicing time is controlled by difference ,1 Td of ,1 T1 and ,1 T2.
• The deicing time and the operation diagram are as following.
