This book was released on 1976 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements to flat plate solar collectors for heating and cooling of buildings have been evaluated through three parallel studies. The first study has demonstrated suppression of free convection by a honeycomb at all angles of inclination. Reductions by a factor of 5 in the free convective heat loss are reported, and equations and charts permitting the rational design of honeycombs for convection suppression in solar collectors are presented. The second study has resulted in a precise, easily programmable set of equations for the free convective heat loss through the air gaps in flat plate solar collectors, for any angle of tilt. The third study has theoretically and experimentally demonstrated that the solar transmittance of a flat transparent cover for a solar collector can be very substantially increased by V-corrugating. Since V-corrugating should also decrease the free convective and radiant losses, substantial improvements in collector efficiency are predicted.

Download or read book Studies on Methods of Reducing Heat Losses from Flat Plate Solar Collectors Progress Report for Period August 1 1974 to July 31 1975 written by Hollands, K. G. T and published by University of Waterloo Research Institute. This book was released on 1975 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements to flat plate solar collectors for heating and cooling of buildings are being evaluated by three parallel studies. The first study has demonstrated that suppression of convective heat transfer by honeycomb panels is possible even when the panel is inclined from the horizontal. The second study has resulted in a precise, simple equation for the free convective heat transfer through an inclined air layer. The third study has theoretically demonstrated that if an inner cover is V-corrugated, its solar transmittance may be enhanced.

This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements to flat plate solar collectors for heating and cooling of buildings are being investigated through two parallel studies. The first study, which deals with the free convective heat loss from V-corrugated absorber plate to a plane glass cover, has shown that, for the same average spacing, the free convective heat loss is greater for a V-corrugated absorber plate than for a plane absorber plate. However, provided the average spacing is large enough, the amount of increase is slight. The second study, which deals with the free convective heat loss in a honeycomb solar collector in which the honeycomb consists of a set of horizontal partitions, or slits, has shown that provided the solar collector is tilted to near vertical, such a honeycomb gives better free convective loss suppression than does a square-celled honeycomb having the same amount of material.
