There are 1.4 billion domestic cooling appliances worldwide
Domestic refrigeration appliances consume
5-7% of all electricity
Average appliance efficiency is only 10%
All of them use gas compressors.
61% of the 200 million units sold annually
world-wide still use high-GWP gases (HFCs)

DOMESTIC REFRIGERATOR FUNCTIONAL VIEW
A domestic refrigerator (both gas compressor based and magnetically
cooled) can be modeled as composed by:
 One “energy conversion device” (i.e. the cooling engine, the heat
exchangers and the temperature control system)
Control system
Cold exchanger
Magnetic cooling
engine
Pump
Hot exchanger
 One “passive system” (i.e. the insulated cold-box)

HOW LCA ANALYSIS HELPED TO NUDGE THE ENGINEERING CHOICE:
EXAMPLE OF FERRITE VS N DF EB PERMANENT MAGNET (1/2)
At thermag VI in September 2014 was announced that Ferrite for permanent magnet
assemblies was an option to be studied due to low cost of Ferrite.

SUCCESS
Technical challenges
- e.g. compactness
Compartmentalized thinking / Inertial behaviour
- Big organization Innovation Governance should be able to catch the value of new opportunities
Systemic complexity
- It takes time to deploy a new technology
- Legislation plays a fundamental role
- Scale matters
Head-on competition
- cost, environmental impact, efficiency of the complete system
Attractiveness for the investors
- Clear Business model and Market introduction
- Change of paradigm (eg. From “market growth” to “market shift”)
Customers want it?
- Awareness, status
