Abstract
Examinations were carried out on a solar heating system with a heat storage unit consisting of a preheating tank to which solar energy is supplied, and a postheating tank where a postheating can take place. The postheating tank is an existing hot water tank. Heat transfer between the tanks can be effectuated by thermosiphoning, i.e. as thermal circulation of the domestic hot water, or by tapping hot water from the system. Some possible designs of the coupling between the preheating and the postheating tank were tested considering the realization of thermosiphoning between them. Designs of suitable standard tanks were studied. Two test stands were built, a model system and a full scale system, in order to carry out experimental measurements with the aim to optimize the design of the coupling. In order to explain how the thermosiphoning between the preheating and the postheating tank affects the annual thermal performance of the systems the simulation program EMGP3 was used. Finally, the economy of a DHW solar heating system with a preheating tank was estimated by comparing its cost/performance ratio with the cost/performance ratio of a traditional solar heating system with one-tank heat storage, and by considering the costs of the auxiliary
