Temperature Mode of the Frozen Base of a Low-Rise Residential Building on a Ventilated Thermal-Insulation Pad

Abstract

The article considers the temperature mode of the foundation of a building constructed on frozen soils according to the first principle without a ventilated underground using deep cooling with seasonal cooling devices (SCD) located in the centre of the building in a channel cooled by outside air. The results of numerical calculations were compared depending on the SCD arrangement methods: along the contour or in the centre of the building in a channel. It is shown that in the second case, the cooling efficiency and stability of the temperature mode of the base are significantly increased due to the stabilization of the annual temperature mode of the base upper layers. As a result, it becomes possible to use a foundation slab that transfers the load to frozen soils.
