The International Institute of Refrigeration (IIR) and US body ASHRAE have spent the last year working to establish common definitions of five commonly used refrigeration words and terms.

After much discussion, both organisations came to an agreement on definitions for cooling, refrigeration, chilling, freezing and the cold chain.

To avoid confusion, the official definitions are:

:Cooling
Removal of heat, usually resulting in a lower temperature and/or phase change
Lowering temperature

:Refrigeration
Cooling of a space, substance or system to lower and/or maintain its temperature below the ambient one (removed heat is rejected at a higher temperature)
.Artificial cooling

:Chilling
Cooling of a substance without freezing it

:Freezing
Solidification phase change of a liquid or the liquid content of a substance, usually due to cooling

:Cold Chain
Series of actions and equipment applied to maintain a product within a specified low-temperature range from harvest/production to consumption

The Science and Technology Council of the IIR officially endorsed the new definitions on February 8, and has called on all national and regional organisations and associations to adopt and disseminate them.
