Modelling of thermal behaviour of walls for low temperature applications: sandwich panel type.

Summary

A model using two ordinary differential equations including the thermal capacity of the external metal layers as well as considering the insulation resistance was more accurate than an algebraic model considering only insulation resistance, but the benefits of increasing the level of complexity were not large. Both models were significantly less accurate as insulation resistance rose. It is probable that insulation thermal capacity must be included if better accuracy is to be achieved.
