Increase in Efficiency of Cooling of the Frozen Basis at the Expense of the Thermal Insulation Blind Area and Vertical Self-Cooling Devices (SCD)
Abstract At traditional decisions the bases of residential buildings of the soil constructed with preservation of a frozen state, basis temperatures in an average zone under the building are much lower, than in extreme zones.

| Summary: | Abstract At traditional decisions the bases of residential buildings of the soil constructed with preservation of a frozen state, basis temperatures in an average zone under the building are much lower, than in extreme zones. It reduces bearing capacity of piles on side axes. In this article, the constructive solutions allowing to cool more evenly the basis due to application additional of the cooling and preserving devices are considered. Regularities of formation of temperature condition of frozen soil were carried out by numerical methods by means of the TEMPA program. on the example of the residential building in permafrost zone. The constructive decision includes the pile bases and the high ventilated underground. The executed calculations showed an opportunity to lower temperature in the work area of extreme piles up to the temperature in a zone of average piles at the expense of the warmed blind area and vertical self-cooling devices (SCD). |
