Outdoor Coil Deicing Protection
This protection is for Heat Pump Only
This protection is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor
heat exchanger temperature must be more than its setting values when finishing the deicing
protection.
In the deicing protection, IFAN is forced OFF.
11.8.5.1 Deicing Starting Conditions
The starting conditions must be made with the outdoor air temperature (OAT) and outdoor coil
temperature (OCT). Under the conditions that the system is in heating operation, after the time for
defrosting is judged to be satisfied, if the temperature for deicing is satisfied after detections for
continuous 3minutes, the deicing operation will start.
Deicing interval time is changed as a function of deicing time. If deicing time is shorter than former
deicing time, the deicing interval time will be increased. If deicing time is longer than former deicing
time, the deicing interval time will be decreased.
11.8.5.2 Deicing Protection Procedure
11.8.5.3 Exiting Deicing
The deicing operation can exit when any of the conditions below is satisfied:
1. OCT>=10
℃
2. OCT>=6
℃
lasts for more than 80s
3. The continuous running time of deicing reaches to 10min.
