LIFE+ Project K-12: Enhanced Insulation Technology for the Refrigerator of the Future offering Energy Savings and Carbon Footprint Reduction

The K-12 Project Background

• The domestic household sector is one of the largest consumers of electrical energy in

the EU, consuming around 30% of the total electrical energy supply, distributed over 140 million households

• The development of new technologies and the adoption of the Energy label have

helped to reduce the energy consumption of individual electrical devices but the increase number and time they are in use resulted in increased energy consumption

 2 K-12 CONFIDENTIAL

increase number and time they are in use resulted in increased energy consumption

• Cold appliances - refrigerators and freezers - accounted for 14.5% of household

energy consumption in 2010. Currently, most households still use old, energy- inefficient cold appliances

The K-12 Project Objectives

• The LIFE+ K-12 project aims to demonstrate the feasibility and effectiveness of an

innovative Polyurethane (PU) technology offering significantly improved thermal insulation and, thus, energy efficiency of households cold appliances, contributing to the European Community’s goals of creating an energy efficient economy while mitigating the threat of global warming

• Manufacturing adaptations will include the design of a new injection equipment and

 3 K-12 CONFIDENTIAL

• Manufacturing adaptations will include the design of a new injection equipment and

innovative refrigerators designs

• Product Life Cycle Assessment (LCA) will be used to quantify the environmental

impact of a potential market introduction of the innovative technology in terms of reduced energy consumption and carbon footprint

The K12 Project Expected Results

• A new refrigerator manufacturing process demonstrated at pilot scale with optimized

foaming parameters and new injection equipment

• A 25-30% improvement in foam thermal conductivity performance of the new PU

foam, compared to the current best in class solutions available today

 4 K-12 CONFIDENTIAL

• A 15-20% reduction in the energy consumption of cold appliances, with respect to

the current best in class labelled A+/A++/A+++

• Demonstrated feasibility of applying the novel insulation material with a zero ODP

(Ozone Depletion Potential) and minimum GWP (Global Warming Potential)

Concentrations of carbon dioxide in the atmosphere have now touched 400 part-per-million and greenhouse gas pollution, but there is no question that the world continues to inexorably climb toward higher levels of greenhouse gases concentrations: at present pace, the world could reach 450 ppm in a few short decades.

What will global annual emissions of GHG be in 2030?

The European Union, United States and China collectively produced 45% of global annual emissions of GHG in 2010

Energy Efficiency has a key role in Abating and Managing Climate Change

• Stabilizing GHGs concentrations in the atmosphere at sustainable levels is key
• Strong reductions in global GHG emissions are needed
• Energy-efficiency is the key response strategy for industry, the key in next decades

 13 K-12 CONFIDENTIAL

• Potential for energy efficiency improvement in there
• Continuous innovation is key for further bridging the gap between old, non-efficient

Energy-using-Products and new generations

• Strategic energy management is essential to recognize and realize the promise of

energy efficiency

The Household Refrigerator stucture

Rigid polyurethane foam is a closed-cell thermoset plastic polymer having the best insulation properties

 14 K-12 CONFIDENTIAL

In addition to the low thermal conductivity, rigid polyurethane foam is stable and durable. Thermal insulation with closed cells rigid polyurethane foam conserves resources, saves energy and has no significant emission to the environment.

How a refrigerator is injected with PU foam?

How far can the PU foam Thermal Conductivity be reduced?

• Smaller cell size
• Lower foam density
• Low thermal conductivity (k) of the gas chosen as blowing agent
• Cell gas mixture with high % low k gas vs. CO2 and Air

however,

 18 K-12 CONFIDENTIAL

however, combination of all these options must be considered, for example

• Reduced density will decrease the solid conduction contribution, but will also

increase the radiation contribution due to thinner cell walls K-12 Project is active in all these aspects and works on reducing all heat transfer and thermal contributions to maximize energy saving
