The selection of a methodology for calculating the heat load of hot water supply systems for facilities with significant uneven consumption

Abstract

When determining the amount of thermal energy required for the functioning of the hot water supply system for any building, the question of choosing a heating method arises. It is especially relevant to accurately predict the capacity of the hot water supply system for facilities with pronounced uneven hot water consumption. In this research, a comparative analysis of methods for determining the maximum design flow rate of hot water was performed, which plays an important role in the selection of equipment for heating water in the flow mode. On the example of the main building of KNUCA, the problem of determining the total design hot water flow rate for buildings characterized by an uneven mode of water consumption is revealed. Monitoring of the actual mode of water consumption of the main building of KNUCA was carried out, as a result of which the real total hot water flow rate during the working day of the university was determined.
