It can easily be related to as the "Rolls Royce" of Air Conditioning Systems. It’s a very sophisticated technological air conditioning system, based on several principles:

  1. Refrigerant only – where refrigerant is the only coolant material in the system (in contrary to the chilled water systems, where refrigerant is used for cooling/heating the water that is circulated throughout the whole system).

  2. Inverter compressors that allow lowering power consumption with partial cooling/heating loads.

  3. Several air handlers (indoor units) on the same refrigerant loop / circuit.

  4. Ability of modular expansion (especially applicable for large projects, that can grow in stages).
