How the Multi System in Melbourne Works

The unit operates in this way:

  • The Multi system consists of a compressor and an efficient condenser coil enclosed in a solid cabinet installed outdoors.
  • It can connect up to five separate indoor units, each set to the required temperatures for optimal levels of comfort.
  • The compressor supplies an adequate amount of refrigerant to every coil, ensuring that each unit receives optimal cooling.
  • Once the desired temperature levels in the rooms is reached, it automatically reduces the refrigerant flow and then maintains the optimum temperature.
  • The system's heart is an inverter-type compressor that automatically adjusts the system's workload to meet the needs of each individual unit.
  • It also considers the selected room temperature with a lesser energy demand, which reduces overall energy consumption after the system achieves & maintains the desired temperature.
