Investigation of edge taping method applied to vacuum insulation panels

'Edge taping method' is investigated as a means to reduce the edge conduction, where insulation stripes are attached along the edges of the envelope. Numerical analyses and experiments are performed to verify this method and an analytical solution is proposed. The results show excellent agreements among themselves and prove that the edge conduction can be substantially reduced by the edge taping. Also, dimensional analysis is performed and the 'easy-to-use' analytical solution is expressed in a dimensionless form. Use of the proposed relation helps one determine a quantitative sizing of physical parameters in the edge taping method.
