Optimalizace provozu chladícího okruhu na Teplárně Karviná

Abstract

This thesis deals with design solutions for optimizing the operation cooling circuit on real block Teplárna Karviná. It contains a theoretical analysis of the cooling circuit of the parts that affect the efficiency of actual heat circuit. The thesis includes a the methodology of the identification of important parameters for evaluating the effectiveness of cooling circuit components, such as the calculation of the actual vapor pressure in the condenser or wet bulb temperature. After knowledge of these factors can make a detailed diagnosis of the cooling circuit and its effect on the thermal efficiency of a real cycle. By defining the shortcomings of the current operation can propose ways of their elimination. The solution is then the choice of frequency converters and pumps to control the flow of cooling water. Finally, speed control is compared with the throttle control valve and calculated return on investment.
