Multi-split air conditioning uses two different compressors

14 August, 2005

The use of different-size compressors in the outdoor units of LG’s Multi-M multi-split system achieves energy savings of up to 35%

The outdoor units of LG’s Multi M multi-split air-conditioning system uses two compressors operating at 40 and 60%, rather than conventional ones working at 100%. This approach allows for energy savings of up to 35%. The load conditions for one or both compressors achieve the desired temperature setting so that it changes to suit demand. Only one compressor is needed for low demand, and both for high. Up to four indoor units can be run off one outdoor unit. Outdoor units are cooling only and cooling/heating. Outputs range from 4.2 to 8.7 kW for cooling and 4.2 to 9.6 kW for heating. All Multi M indoor units have a hand-held infra-red remote controller for temperature settings, mode selection, air circulation and fan operation. Other control options include a hard-wired central unit that can control all the indoor units.
