1 Working principle for press on and off
When inner temperature reaches set temperature, induct the temperature by sensor and change into
electrical signal which is sent to control chip of computer board. By pre-set procedure, the chip then sends
out stop order to compressor to shut it down. When the inner temperature is returned 1
℃
higher than set
temperature, the chip sends out stop order via the same procedure to shut the compressor down. (If
temperature return in the refrigerator is too fast, less than 5 minutes, then take it as 5 minutes.)
2 Working principle for fan on and off
The fan is in synchronous operation with the compressor. Please refer to 6-1 press working principle for
fan working principle.
