Description
According to the International Institute of Refrigeration, (1) 20% of the global warming potential of refrigerating and air-conditioning systems comes from leaks (direct emissions), while 80% results from their energy consumption (indirect emissions). Today's refrigeration systems consume around 15% of the world's available electrical energy. Reducing their energy demand would make an important contribution to reducing the threat of global warming. In this context, special importance is attributed to natural refrigerants such as ammonia, carbon dioxide and hydrocarbons, which offer high energy efficiency as well as being climate-neutral. Expert opinion recognizes ammonia as the most efficient refrigerant. But hydrocarbons such as propane, propene and isobutane also have outstanding thermodynamic properties; refrigerating and air-conditioning systems that run on these refrigerants are particularly energy-efficient. Companies such as Ben & Jerry's, Pepsi and Unilever use hydrocarbons for refrigeration in their chilling units and freezers. Various tests in the field have confirmed energy savings between 10% and 30% compared to HFC systems.
