Inverter Multi-Split Systems
Rather than using a constant speed compressor, the inverter system uses a variable speed compressor, which means the Cooling or Heating capacity of the air conditioning system can be varied to suit indoor conditions in each room.
This makes the Inverter Multi Systems more economical and efficient to operate and produce less noise than standard counterparts on the market today.
How does Multi-Split Air Conditioning work?
A multi-split AC has one outdoor compressor, connected to four to five indoor air outlets via refrigerant lines rather than a complex duct system. Apart from the refrigerant tubing, the indoor air outlets are connected to the outdoor unit with condensate drain lines and power cables.
Although each indoor air outlets can be separately controlled, they are connected with the same outdoor heat pump unit to absorb or disperse heat. A heat pump works by removing the heat from the outdoor environment and transferring it indoors.
