Modelling of process of warming up of concrete in thermal installation at various heat carriers

Purpose. Multi-layered wall reinforced-concrete panels are produced by a stand method. For the decline of value of their production it is necessary to conduct modernisation of the thermal setting. For the improvement of the thermal setting it is necessary to investigate the process of heat exchange of the stratified construction at her warming up. At research it is necessary to take into account influence of different terms. Methodology. For research of process of thermal treatment of construction, the model of the thermal setting was worked out. Thermal treatment of production of collapsible reinforce-concrete double-layer wall panels a stand method is designed. Design basis is made by the system of equalization's of heat-mass change realized by the methods of CAD/CAE. The processes of heat conductivity, convective and radiative heat exchange are designed. At the design of thermal work of stand middle initial conditions were accepted corresponding to warm and cold periods. Findings. The design of process of thermal treatment of double-layer element is executed. A model imitated the fragment of a wall panel. The calculations of warming up of layers of element of construction are conducted. At calculations changed: modes of operations of the thermal setting: type of coolant-moderator; parameters of construction (thickness of layers and their correlation); initial temperatures of coolant-moderator; ambient temperature. The analysis of the data obtained at a design is executed. Basic data is certain for planning of the thermal setting, providing the production of constructions such The calculations of the different modes of operations of stand are conducted for some types of double-layer constructions. Basic data is certain for projecting of the thermal setting providing a stand method production of the combined teams reinforce-concrete double-layer constructions of such type. Originality. The model of the thermal setting realizing the stand method of production was created. Within the framework of model a double-layer construction is investigated from the concrete and heat isolation. The border terms of thermal treatment of double-layer construction changed at research. Practical value. The calculations of the different modes of operations of stand are conducted for some types of double-layer constructions. Basic data are certain for planning of the thermal setting providing a stand method production of collapsible reinforce-concrete double-layer constructions of such type.
