How would the world look like without artificial cold ?

The cold : an evident application on food …

The food cold chain … from the first ages to the 1800’ths

One can estimate that approx 60% of the food we eat in developed countries needs cold application :

530 kG/hab. year of solid foods, incl.308 kg of refrigerated food42 kg of frozen food.

Over the 4 500 Mt of the food produced worldwide, 1 500 Mt could be refrigerated to good effect … but only 350 MT are actually refrigerated.

25% up to 30% of the world food production is lost; the application of cold could save a large amount of this food.

3 million death per year are caused by unhealthy diet; the application of cold could drastically reduce this deplorable score.

An evidence : The cold is largely used in the food industry domain …

The cold production is mainly based on vapour compression cycles with liquid/vapour phase change (Cf R. Aguilo)

CFC, HCFC, HFCand other refrigerants

Mission of the IIR

To promote expansion of knowledge and to disseminate information

• on all refrigeration technologies and • all applications • for the benefit of humanity

To promote knowledge of refrigeration technologies and all applications in order to address today’s major issues

• Food safety• Protection of the environment

– Reduction of global warming– Prevention of ozone depletion

• Development of the least developed countries– Food – Health
