DOI:https://doi.org/10.2172/6789860· OSTI ID:6789860
The test procedures used and the results obtained during the evaluation test program of the Lennox/Honeywell double covered liquid solar collector are presented. The tests were performed under simulated conditions, following long-term exposure to natural weathering conditions. The Lennox/Honeywell collector is a flat-plate solar collector. The absorber plate is steel with copper tubes bonded on the upper surface, and is coated with black chrome with an absorptivity factor of .95 and emissivity factor of .12. It has a double glass cover of 1/8-inch tempered glass and weighs about 153 pounds. The overall dimensions of the collector are 3' x 6' x 6-1/2''.
