Assessment of process heating and cooling demand for solar system installation at typical industries in Ethiopia

Abstract
Several measures that bring about structural change in the economy of Ethiopia have been taken to achieve the overall goal of the industrial development strategy. However, the substantial share of fossil fuels and electricity requirement has been increased the burden on the trade balance of the imported petroleum volume and the Ethiopian power system. With this, considerable attention is being given for the energy that can be met alternatively using solar radiation which might be quite effective and economically competitive to the conventional systems as most regions in the country experience a more or less good intensity and uniform solar radiation. The development of an economically feasible and energy-efficient solar system requires validation through studies. Hence, the assessment of heating and cooling potential to identify the load profile which is non- existent mostly is necessary. Looking into the majority of solar industrial processes operating worldwide and the industrial sector development in Ethiopia, a survey has been made of two target industries (leather and soft drinks). The load profile results for the case studies at Sheba Leather Industry P.L.C. and MOHA Soft Drinks S.C showed a considerable demand for hot water at temperatures approximately equal to 35-55 C-0 and 60-85 C-0 respectively. The corresponding energy needed to heat the amount of water per day is estimated to be 10 GJ and 54 GJ. There is also a significant cold water-glycol solution demand at a temperature approximately equal to 4 C-0 with a corresponding estimated daily cooling capacity of 21 GJ in MOHA. These relevant results and the identified daily, weekly, and annual load profile will have significant importance for cost-effective energy substitution and conservation measures.
