GEA Refrigeration Netherlands N.V. won the Dutch Refrigeration Prize last month for technology that combines a refrigerating plant and a heat pump. The Dutch Association of Companies in the Field of Refrigeration Technology and Air Treatment (NVKL) has awarded this prize since 1989 to recognize innovations in the area of refrigeration and HVAC.
The Energy Enhancer, the name given by GEA to this refrigeration-heat solution, convinced the contest jury of its energy-savings potential. The solution uses an ammonia heat pump to raise the temperature of the heat exhausted from refrigeration compressors (originally emitted at about 35°C [95°F]) to a level of 80°C (176°F), which can be effectively used as a heat source for processes throughout the plant. This enables efficient use of heat in, for example, milk pasteurization, French fries production (blanching) and meat processing (cleaning machines). The heat can also be used anywhere else it’s needed, such as in heating the plant’s environment.
