Economy

Cutting edge inverter system technology offers high efficiency and economical operation.

is a high efficiency inverter system

uses frequency controlled inverter compressor(s) and fan motor(s), to enable capacity

control according to the indoor load. has a 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.
