Abstract
An arrangement of insulating, thermal absorbing and/or dissipating elements controlling heat flow between a member and its environment. In certain permafrost environments, for example, one or more elements of the system can include a heat sink and/or a thermal bleed where the member is heated. The arrangement controls heat flow from a heated member at such a rate that the total heat transfer does not exceed the limits of the residual heat capacity of permafrost below the freezing point thereof during cyclic climatic influences. The arrangement takes advantage of the fact that artificial heat from the heated member can be controlled, while natural solar heat is balanced by the seasons. The elements also serve to maintain relatively stable temperature differentials between heated or cryogenic materials and their adjacent ground support, so there is a minimal effect of one on the other.
