1 December 1983 Heat Loss Mechanisms In Transparent Insulation With Honeycomb Structures
Author Affiliations +
The development of highly transparent insulation materials is an important step in raising the efficiency of flat plate collectors and for passive use of solar energy in buildings. The problem in combining selective absorbers and honeycomb structures is that the radiation losses due to thermal emission of the material of the structure may be larger than the losses due to convection which are present without the structure. Therefore a thorough analysis of the different loss mechanisms has been made. There are two possibilities for overcoming these difficulties. The first is the use of materials with low absorptance in the infrared or with selective surfaces for the honeycomb structure. The second possibility is the use of highly IR-absorbing materials. In the latter case a selective absorber is not needed. Results from both approaches will be presented.
