INVESTIGATION OF HEAT TRANSFER VIA GROUND IN BUILDING WITH UNHEATED BASEMENT

Abstract

With using non-steady calculation of temperature fields in ground have made parametric analysis of heat transfer from building through first floor slab over unheated basement. Heat balance defined as equality of heat transfer through first floor slab and through basement walls and floor. It is investigated influence of insulations (first floor slab, floor and walls of basement, blind area), geometric parameters (depth and width of the basement and width of the blind area) and of groundwater (depth and mobility). As the aim parameter used heat transfer resistance to outside air in steady state (calculation period about several decennaries). Simulations was made on example of Moscow region.
