Abstract

This paper presents the optimized solution of a solar system for providing domestic hot water through the results of a system work simulation done on an hourly basis for a motel with capacity of 35 persons located in climate areas of Zagreb and Split. The analyzed system consists of two tanks for domestic hot water, capacity 1600 liters each, and appropriate collector area (43,7 m² for Zagreb and 30,4 m² for Split). The basic criterion for optimization was the shortest investment payback period with a primary goal to cover the energy demands for domestic hot water in July and August. This paper presents monthly and yearly results of performed simulation for both climate areas and description of the calculation procedure for estimating solar radiation and energy gain.
