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 opera-
tion and current ambient temperature is over 3°C (to reduce the hyster-
esis with the temperature difference when operating FFH), FFH is oper-
ated 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.
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.
