Optimization of heat transfer processes in enclosing structures of architectural monuments located outside urban agglomeration

Numerous architectural monuments throughout Ukraine were once proud and were the center of historical events. With a glorious and rich history, but forgotten by people because they are located outside the city limits and are not included in well-known tourist routes. Historic buildings are examples of neoclassicism, baroque, neo-gothic and many other styles. During Soviet times, they were turned into barracks, chemical storage facilities, food and weapon warehouses, and now they are empty and collapsing. A correct and calculated approach to reconstruction, restoration and monitoring of their further condition will make it possible to turn such objects into the cultural and historical center of a rural agglomeration. This will help maintain historical memory, preserve culture and heritage, and also give economic impetus to the development of the area where they are located. Leakage of worn-out enclosing structures is the biggest problem of abandoned architectural monuments. This causes uneven wetting of the structures. And then the task is posed of how to properly dry such enclosing structures and not damage them. All these old building envelopes are colloidal capillary porous bodies (CCPB). Drying of such massive structures occurs due to heating. The problem of the optimal heating rate of a massive colloidal capillary-porous body is considered. The restrictions that are imposed on the internal thermal stresses in the specified body are taken into account, especially at the first low-temperature stage when heating the colloidal capillary porous bodies. Due to the temperature distribution over the mass (over the cross-section) of the colloidal capillary porous bodies, compressive and tensile stresses arise inside the body. Colloidal capillary porous bodies can be destroyed by these stresses, leading to the appearance of various microdefects.
