Typically, these facilities run independently of each other even if they are a part of the energy system in the companies. There are only a handful of companies that need steam and in most cases hot water up to 80-100°C is sufficient. Institute for Energy Technology has done research on energy recovery in an industrial context, and especially within the food industry since 1995. This has resulted in a hybrid heat pump (compression / absorption heat pump) using a mixture of ammonia and water as working fluid. The hybrid heat pump has the capability to deliver hot water up to 100°C, recovering waste heat at approx 50°C. This paper presents operational experiences with a specific hybrid heat pumps installation at a Norwegian slaughterhouse. The hybrid heat pump recovers heat from the refrigeration system and produce hot water at 90°C.en620 Ingenieurwissenschaften und zugeordnete TätigkeitenAmmonia-water mixtureFood industryIndustrial heat pumpsWaste heat recoveryBook Part
