The Comparison of Two Different Solar Collectors Systems
Abstract
The major purpose of this work is to investigate the efficiency of two working solar collectors systems using for domestic hot water in Lithuania (Kaunas city) and to compare their technical – economical indicators either. First system contains flat plate solar collectors, the second one – vacuum tube. The conditions for exploiting the systems mentioned above are basically the same: in both houses live two hot water users. In this research at the first step both systems efficiency and other technical indicators have been calculated using software. Moreover, the amount of heat energy (produced by these systems) is being measured using remote data acquisition system. Considering the technical and economical peculiarities of these systems in Lithuania (the exploitation, system life period, payback time), system with flat plate collectors has more obvious advantages than the other one that has been chosen for comparison in this investigation.
