Based on the basement temperature set according to exploitation conditions, and deciding again the equation relative to Ky and K2 coefficients, you can determine what thermal conductivity the walls enclosing the basement and overlap should have. For the conditions of our average climate, the thermal conductivity coefficient KX for the basements immersed in the ground turns out to be close to 0.3. The vegetable stores built with this coefficient do not really give a decrease in temperature below zero.
Encouragements of certain meanings. Such basements, no matter how we reduce the thermal conductivity of walls and floors, will always have a temperature below zero, and therefore in order to have at least a minimum positive temperature in the basement, it is necessary to heat it.
If we consider the same case, but provided that the basement is under the heated building (404A), the temperature of which is above the basement overlap about – J – 20 °, an equation that expresses the equality between the arrival and caring of heat in the basement, is written like this: this is written:
The worsening of the walls of the basements is easiest to make with their overlapping with heat with heat slabs (from a warm loaf, reeds, fibrilite, etc. D.). Recks are installed on the walls, firmly related to masonry, to which slabs are attached, followed. To the floor, if it remains earthen, it is good to put a layer of slag with a thickness of 5 cm.
When the basement landowner is intended for housing, it is necessary to take measures so that they have a normal residential temperature (not lower than 18 ° C), they are dry and received from the outside in a sufficient amount of light and air.
In this case, in addition to isolation and wovers of the gene and floor, it is necessary to take care of wrapping and ventilation of the basements.
If central heating operates in the entire building, it must be arranged in the semi -basement rooms so that these rooms have an influx of fresh, dry, heated air.
Rely on natural ventilation through windows in the lane conditions cannot. Extra ventilation should be installed with a motive for stretching spoiled air and replacing it fresh from the chamber when heating. If there is no central heating or it is not able to warm the low -located semi -basement rooms, it is best to arrange ordinary Dutch heating with wood or coal, as it heats and dries the room and ventilates it.
