Simulation of the solar domestic hot water system operation

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 analysed system is consisting of two tanks for domestic hot water, capacity 1600 litres each, and appropriate collector area (43, 7 m&sup2 ; ; for Zagreb and 30, 4 m&sup2 ; ; for Split). The basic criteria 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 presentes both monthly and yearly results of performed simulation for both climate areas and description of the calculation procedure for estimating solar radiation and energy gain.
