10. FFH OPERATING PROCESS
1) Operating Condition
FFH is operated according to the ambient temperature and coolant tempreature.
(1) Initial Operating Conditions of FFH
▶ Initial Operating Conditions of FFH
- Ambient temperature: below 5°C
-
Coolant temperature: below 75°C
▶ Repeated Operating Conditions of FFH
-
Coolant temperature: below 75°C
- When the difference between the ambient temperature at initial operation and current
ambient temperature is over 3°C (to reduce the hysteresis with the temperature
difference when operating FFH), FFH is operated again.
For example, if the initial operating temperature was 4°C, the ambient temperature at
repeat operation should be below 1°C and the coolant temperature should be below
75°C.
(2) FFH Operations According To the Changes of Coolant Temperature
Above graph shows the FFH control process while the FFH is operating.
The control element is coolant temperature as shown in the graph.
The FFH is operated in HI mode (high output: approx. 5,000 W) until the coolant temperature
reaches at 80°C and starts to be operated in LO mode (low output: approx. 2,300 W) from
81°C.
When the coolant temperature reaches at approx. 85°C, FFH stops its operation until the
operating conditions will be met again.
