inverter system
compressor(s) and fan motor(s), to enable capacity

COP of 3.9 in cooling, and 4.1 in heating.
Precise inverter control ensures quick cooling and
heating, with minimum temperature deviation
When the outside temperature is relatively stable, the compressor
frequency is reduced, (it is not stopped) to ensure comfortable room
temperatures. The desired temperature it obtained quickly by increasing
the compressor frequency as the indoor unit load requires it to do so.
