THE ENERGY CONSUMPTION OF REFRIGERATION INSTALLATIONS AND HEAT PUMP POTENTIAL IN 40 DUTCH INDUSTRIAL SECTORS

KWA Business Consultants has carried out a study into the annual energy consumption of refrigeration installations in the Netherlands. The study shows the energy consumption of detailed sectors that use refrigeration. A large number of industrial sectors (such as chemical industry, dairy, beer, cold stores) has been distinguished and also various non industrial sectors (such as buildings air conditioning, supermarkets, agricultural sectors). With knowledge of these figures innovate companies may put focus on energy savings by improvement of refrigeration components, systems and controls in particular sectors. Refrigeration installations deliver residual heat. This heat amount can be supplied to heat processes and buildings at moderate temperatures. By use of heat pumps this residual heat can be raised in temperature and reused more effectively. The use of fossil fuels for heating purposes is reduced significantly. The food and drug industry sectors have an electrical energy consumption of 23 PJ in total. Refrigeration consumes 6 PJ, which is a share of 26%. The non-industrial sectors have an electrical energy consumption of 42 PJ in total. Refrigeration consumes 10 PJ, which is a share of 24%.
