5. Half of the European systems are central chillers
RAC (36%)
71% Chiller in CAC
CAC (64%)
RAC < 12 kW = Room Air Conditioning
VRF = Variable Refrigerant Flow
Rooftops = Centralised unit for series of rooms
Packages = Combined unit of Air Conditioner and Central heater
Splits > 12 kW = Centralised units for buildings (Multi-Split)
Chillers = Central unit to generate chilled water for Air Condition
CAC = Central Air Conditioning

8. Economics- Solar Assisted Cooling will pay off.
Price indication
investment depends on project
semi-standardised solutions
higher investment costs will be balanced by lower energy cost

9. Our world is full of energy.
