Domestic hot water and space heating. Solar systems. Collector efficiency test

摘要

The scope of the solar collector tests related to solar space and water heating was outdoor laboratory measurements of different types of non-concentrating collectors using liquid heat transfer fluid. The solar collectors or collector arrays have to be designed in such a way that they have only one inlet and one outlet. The main purpose of the testing was to construct a thermal efficiency curve. The presented results were used as input data in a computerized simulation programme for determining the thermal performance of solar systems. They can be used as a basis for recommendations for further improvement of the collectors, for validation of computer models and as a tool for finding defects in design. (AB)
