Book Description
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.

Book Description
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.
