Keen on hearing about the everyday performance of this U-Crown .
Here below a test (made by Gree) for 18 BTU applied in Europe (see: QXAT-B121 compressor instead of B20 for US/CAN):

=> indicating bad on/off cycling- behaviour at relatively low output capacity (around 1000W)
Note: only capillary control after "intercooler/flash vaporizer)
U-Crown 12UB (under brand C&H) tested also in Scandinavia 6/2016 vs. Daikin+Panasonic R32-versions.Some appetizers attached .
Note:
The testing upto -15degC controlled by inverters (against burden 2000/3500W) and further upto -30degC at full speed
In all data defrost included !!!!!!!!!!!!!
Result:
U-Crown 12UB has a "lousy heating performance" (COP) at mild ambient conditions due to frequent on/off- cycling tendency
