Experimental Monitoring of Hot Water Supply Systems

conference paper

English

The paper presents the partial research results from experimental monitoring of existing central domestic hot water production and distribution systems within residential buildings in the Czech Republic. The goal of mentioned investigation is to determine real thermal and hydraulic behaviour of these systems, evaluate the results and take appropriate conclusions for practical design. The paper is primarily aimed at the monitoring: (a) maximum flow (peak flow) of hot water delivered to the plumbing fixtures, (b) division of hot water consumption during the day. Experimental measurements in the duration of one to three weeks were realized in three residential buildings with the number of 32 to 60 flats. In spite of the wide spectrum of obtained results it is possible to state that the hourly consumption peaks are usually concentrated to evening or to morning hours but the peak flow also appears except these periods. Furthermore there was found out that the time variations of water consumption, which are expressed in the variation coefficients, are within the monitored residential buildings in practice similar and without substantial dependency on the season. Generalization to detailed conclusions is determinated by long-term measurements.
