Modeling of cold room driven by an absorption refrigerator in the south of Tunisia: A detailed energy and thermodynamic analysis

摘要: Abstract This paper deals with the performance modeling of a cold room used for food storage in south Tunisia. The cooling process is properly carried out purpose to insure high quality and safety products. An overview system presented. A theoretical model developed discerning thermal load date's refrigeration. heat supplied generator provided by solar collector. error about 1.5% noticed between experimental results. It could be well-thought-out as good agreement. To make program universal usage, an interface application predict required any considered operating conditions. Furthermore, main optimal parameters achieved improving wall insulation or controlling working conditions (working hours, number workers). refrigeration capacity generated evaporator ammonia/water absorption system. computer code based on thermodynamic properties ammonia-water mixture performed optimize cycle performances. For coefficient (COP) 0.74 8 kW, flux 11 kW.
