(Total Cost of Ownership): assessing the life cycle of a solution • Energy efficiency • Simple and quick maintenance • Limited downtime costs

  31. Increased sustainability • Efficiency • Monitoring refrigerant leaks • Low impact on global warming • Sustainable materials

  32. Efficiency is sustainability Efficiency means consuming less An efficient unit respects the environment by minimising CO2 emissions when producing energy 3,5 3,4 3,3 EER 3,2 3,1 3 42,1 49,4 56,9 66,7 74,7 84,7 95 kW

  33. Monitoring refrigerant leaks • Electronic expansion valve • Monitoring the operating parameters of the unit • Management of leaks • Intervention before the whole load is released into the environment

  34. Global warming • Total Equivalent Warming Impact • Refrigerant emmissions during the life cycle of the unit • Indirect emmissions due to CO2 released in electricity generation

  35. Environmentally friendly design • Sustainable materials • Use of recyclable materials • Reduced use of limited raw materials • “Slim” refrigerant circuit for reduced use of resources such as copper and aluminium
