Q: Under what circumstances air conditioning is beginning to defrost? A: general US Air defrost enter have these types: The first entry conditions: 1, when about 5 minutes into the heating mode or defrost mode, depending on the outside machine coil temperature and the maximum difference between the indoor temperature to identify, finds time of 3 minutes. 2, when the above inner coil temperature and indoor temperature difference between 5 degrees and smaller than 3 minutes, 3, ensure that the compressor accumulated operating time more than 45 minutes, 4, the indoor coil temperature is less than 48 degrees, while meeting the four then entered a flower cream. The second condition: compressor total running time over 45 minutes, and run more than 20 minutes of continuous coil temperature is lower than the indoor temperature is 16 degrees 5 minutes into the defrost state. Third various conditions: compressor cumulative operation more than three hours of continuous operation over 20 minutes coil temperature is less than the indoor temperature is 16 degrees 5 minutes into the defrost state. Fourth various conditions: Outside air enters into overload and outside the fan stops, the outer fan next start continuous operation longer than 10 minutes Xuzhou air conditioning repair quote, but also to ensure that the compressor total running time over 45 minutes or 20 minutes of continuous revolution indoor coil pipe temperature is less than 48 degrees is entered defrosting state. Fifth various conditions: outside the fan stops and two hours have not yet entered the defrost, the defrost forced entry. 1. Stop the air conditioner frequently open problem: too much fouling drain pan, drain clogging answer: Clear water tray, open the drain hole 2.

Unplug the power cord. Exceptionally important to note that must unplug the power plug. Second, remove the indoor and outdoor machine with three, open the outdoor unit Copper Pipe Fittings (plastic sheeting wrapped Xuzhou Hitachi central air conditioning sales, avoid into the soil), open outdoor electromechanical cable connector (particularly need to remember the line sequence) Fourth, The same is true when installed prior to the opening of the outdoor unit small brass, with a little bit of air blowing fluorine indoor unit (10 seconds), then turn off the big brass.
