Here is Tony, the sales manager from Zhongshan Amitime Electric Co.,Ltd. writting to you. The visit we paid to Krister this time is only a business visit so we didnot bring any engineers here. When we backed to China or when our chief engineer Joe comes Sweden sometime, we will try to answer some questions. Sorry....''
Regarding the defrosting issue, I should say that it is really hard to let the unit know when it should defrost and when it should stop defrost, as the unit can only clarify this through some simple datas, like the Temp. And, we have to ensure the unit will defrost all ice away even in the hardest condition (when the air Temp is a little bit higher than 0, not the lowest air Temp). This is why sometimes the unit defrost more time than necessary.
Now the unit starts and stops the defrosting mainly according to the Temp of the condensor pipe. Do you have any good suggestion about defrosting? If yes, hope you are willing to share with us, so we can apply this better solution to our future products. Thank you!
