Heat exchange in cylindrical foil solar collectors. Part II


, : Heat exchange in cylindrical foil solar collectors. Part II. Roczniki Nauk Rolniczych, C Technika Rolnicza 77(3): 133-139

Results of tests on cylindrical foil collectors are compared with results of theoretical calculations performed by the method described in part I (A. Chochowski, Wymiana Ciepta w Walcowych Powietrznych Kolektorach Sonecznych, Cz I (Heat exchange in cylindrical foil collectors), Roczniki Nauk Rolniczych, 1986, 77 (3), 110-123) by which the effect of constructional and operational parameters on final temp. increase efficiency and useful power values can be determined.
