A small minimum of the total annual cost was found in Figure 1, 5 and 6 with the reference costs for the three weather conditions. When increasing the auxiliary fuel cost in Figure 2 the minimum is more marked at around 20,000m2 collector area for a storage volume of 20,000m3 this means a solar fraction […]

The analysis is mainly done by taking out one reference case after a series of single point evaluations. As there was a striving towards a high solar fraction the reference case with the actual auxiliary fuel cost is not the minimum average annual cost which is depicted in Figure 7. The reference case is: • […]

Input data values are those recommended by the appropriate IEA task experts, except where specific to the Swedish Case Study. The weather data used is Boston, Madison and Copenhagen which does not fit very well with the local climate in Uppsala. Therefore the reference case in the simulations has a collector area of 20,000 m^. […]

The solar collectors are centrally located on a field about 500m away from the storage. The collectors are single glazed with one 4 mm thick toughened glass cover and two transparent teflon films underneath. Each collector is 12m^ and the absorber consists of an aluminum plate with a selective layer. The fluid (water/glycol) flows in […]

In general the MINSUN program did perform well. The results seem to be reliable and the program is fast enough to be used for optimization purposes. In the third section above, some remarks are made concerning some features which are recommended to be included in future versions of the program. The *manual* optimization method as […]

The purpose of the performance analysis is two-fold: • to establish and optimize the performance of the solar heating system, • to test the MINSUN program in its present form, for as far as the system simulation and optimization are concerned. The performance analysis carried out has been as follows: First, via best guess and […]
