Assessment of a Possibility of Partial use the Cold Ventilated Spaces under Buildings in the Permafrost Zone

[摘要] Researches are executed on the example of the existing house in a Permafrost zone. The constructive decision includes the pile bases and the high ventilated spaces under buildings. In work is offered to estimate an opportunity to lower the room for a ladder directly on a planning surface without the ventilated gap. For reduction of thermal influence the insulation device under floor of this room is offered. The possibilities of additional cooling of the frozen basis by means of the cold pile bases with the built-in liquid thermosiphons of coaxial type are considered. Options with the device of cold pile bases and without them are considered. Regularities of formation of temperature condition of frozen soil were carried out by numerical methods by means of the TEMPA program.
