Design of a solar driven cooling unit based on the diffusion absorption principle

Obiettivo



To cover the increasing cooling demand, worldwide research efforts are being ma de for developing environmentally friendly energy saving alternatives to common ly used electrically powered compression cooling units. Thermal driven absorpti on cooling aggregates using ozon friendly working fluids are recognized as an a lternative to the compression cooling technology using Chloro-fluoro-carbon (CF C) containing refrigerants. Absorption cooling units driven by a thermal solar system can substitute environmental hazardous substances (CFCs; Ozon Layer) as well as save energy (CO2; Greenhouse Effect). Up to now, no cooling units are a vailable for the small and medium cooling performance range (2-50 kW) that can be solar thermally powered without technical or economical restrictions. Dir ectly gas powered NH3/H2O diffusion absorption cooling units are known from the refrigerator field (0,1-0,2 kW) to be inexpensive, long lasting and free of ma intenance aggregates. It's the objective of the project to further develop a di ffusion absorption cooling unit to an indirectly heated, solar driven cooling u nit with 2,5 kW cooling performance. Furthermore, the appropriate system techno logy such as solar-, cold distribution- and controlling system will be designed . The envisaged developments require outstanding know-how of the participating small and medium sized enterprisis (SME) and research and technical development (RTD) performers. The technical risks are high, but well considered. The solar powered diffusion absorption units can be used for residential, industrial and for food cooling applications and will improve living- and working conditions, food quality and supply, especially in less developed countries. Besides as a solar driven cooling unit, the aggregate can also be used as an environmentally friendly heat pump. The development of a solar driven cooling unit based on the diffusion absorption principle will have favourable economical effects for the SMEs of the core group and other European SMEs in the cooling- and solar t echnology sector. A product will be developed for an increasing market, especia lly in southern Europe and other areas, where high solar radiation meets high c ooling demand. It will enable the European solar- and cooling industry to be ah ead of Asian and US competitors referring to know-how and marketable products i n the field of solar cooling technology. Through joint research and developm ent the SME-core group will establish a basis for further cooperation on the Eu ropean level. After a six months demonstration phase and development to a seria l product, the core group plans to market the unit and a solar cooling set in l arge scale. A return on investment of one year is expected following implementa tion of commercial exploitation.
