Dynamic Pinch Analysis

Abstract

Needs for heating and cooling in Serbia is growing up. Existing systems in buildings and industrial processes are increasingly using renewable energy. To improve the competitiveness of the domestic economy, a great character given to improving energy efficiency. The paper analyzes the possibility of integrating technological processes with heating and cooling systems at the plant for production of mineral water. The aim is to improve the energy efficiency of the system both considered by mutual integration into a single system with the use of locally available renewable energy. Integrating is analyzed using a "pinch" analysis (methods of minimum temperature difference). The aim of this work is to improve the model by means of the acquisition of physical parameters and influence the process of exchanging heat of warm and cold currents were optimal energy-saving energy. The first part represents the composite and the cumulative curve in the case of an industrial process, and determines the state of the necessary energy in the summer and winter period and of the technological HVAC systems. The second part shows the variable pinch point in the summer and winter periods on the basis of changes in ambient temperature and technological process. Possibility of year-long use of geothermal heat pumps and geothermal energy.
