POTENTIAL APPLICATION OF SOLAR PROCESS HEAT IN THE MEAT SECTOR CONSIDERING HEAT RECOVERY AND INDUSTRIAL HEAT PUMPS AS COMPETING TECHNOLOGIES

摘要

Food industry, specifically the slaughter and meat processing industry, is a promising field for solar processrnheat. Several processes, such as scalding or hot water generation for washing and cleaning, offer feasiblernintegration points due to the low temperature level and conventional heating equipment. For the German meatrnsector, a technical potential of one million square meters of collector area was estimated. However, heatrnrecovery systems can reduce this potential significantly, especially if they are installed in combination withrnindustrial heat pumps. Thus, the questions arise how heat recovery systems can be operated most economicallyrnwith respect to the condensation temperature of compression chillers and which influences have to be expectedrnfor the integration of solar heat and industrial heat pumps.
