Special Working Groups

Refrigeration Special Working Group - 2008


The Refrigeration SWG clearly demonstrated that refrigeration offers important opportunities for saving energy and identified areas that require further work.


  • Examine energy efficiency in industrial refrigeration, covering installations using process-chilled heat transfer fuids and installations generating chilled water to supply cooling coils for space air-conditioning

Members: 15 companies

Activities: Surveys were carried out on the refrigeration system of each member company.


  • Surveys identified savings of around 16 GWh of electrical energy, equal to €2.047 million in energy savings and a reduction of 8,744 tonnes in CO2
  • Report and technical summary of the findings, detailing typical bad practices and energy-saving opportunities
  • Fact sheets

Opportunities identified

  • Potential to reduce refrigeration energy usage on site by 24% (on average) even though these energy-aware companies had previously implemented many energy-saving measures
