OPTIMIZATION OF HEAT-SHIELDING CHARACTERISTICS OF THE EXTERIOR WALLS OF COUNTRY COTTAGES, INSULATED WITH MONOLITHIC FOAM CONCRETE
The heat-shielding properties of three-layer external walls insulated with monolithic foam concrete are considered in the article. The temperature is given in rooms operated in intermitt ent heating conditions. An optimal exterior wall design is proposed using monolithic foam concrete for the construction of country cott ages. For this design, the results of heat engineering calculations are presented using the analytical dependence of determining the heat transfer resistance, which ensures the minimum warm-up time of the wall. The results of the calculation are presented in tabular form for a given heating time and density of foam concrete. Also a relationship is described to determine the maximum allowable resistance to heat transfer of the outer wall at diff erent densities of monolithic foam concrete.
