The first point to understand about refrigeration theory is that heat is energy, and it can be made to move. If enough heat is removed from a glass of water, the water will freeze to ice. When that heat is allowed to move back into the ice, the ice will melt.

Make way for the new class of refrigerants that await its entry in the global commercial markets. These are not the generic class of compounds that have been haunting the dreams and discussions of active environmental activists and forums respectively. When the world is out on the hunt for fresh additions to the list of already known refrigerants in the market, their approach is fixated to a singular point of product development — aim at coolants with low-global warming potential (GWP). 

The global refrigerants market was valued at $9.5 billion in 2015, and is projected to reach $18.5 billion by 2022, registering a compound annual growth rate (CAGR) of 9.9 percent from 2016 to 2022, according to a new report published by Allied Market Research.

The 2016 editions of ASHRAE’s major refrigerants-related standards have been published as a package with 30 new refrigerants and refrigerant blends added.

Danfoss has launched a mobile training unit equipped with carbon dioxide (CO₂) solutions and interactive learning modules to help boost CO₂ refrigeration system competency among system builders, refrigeration contractors, service technicians, installers, and technical departments of food retailers.
