7 Determination
defrost
1. When press the fuzzy button, predictable cooling of freezer
and fridge room is started.
2. How to predict freezer and fridge room temperature.
1) Checking accumulated door open time every 2 hours.
2) Decision of open door frequency is as follow
•
Above 30 sec. : Door is opened frequently. (1)
•
Below 30 sec. : Door is not opened frequently. (0)
3) Decision of data is for 8 days.
•
If the accumulated open door time of 30 sec. is more
than 6 times for 8 days, then data decision will be high.
•
If RT-sensor<14˚C, it is operated mid instead of high.
4) Example
1. Necessary condition of determination defrost
1) COMP. operation accumulation time (6, 9, 12, 15 hours)
2) COMP. operation ratio (COMP. accumulation time is divided
by 3 hours)
3) Door open accumulation time.
4) Total time (COMP. on time+COMP. off time) is 60 hours.
5) Outside temperature is above 35˚C.
6) Various error
•
D-sensor error
•
F-sensor error
