Petrenko A. Providing of optimum terms of microclimate taking into account the design of the thermal mode of apartment

The object of the research is microclimate in premises of buildings. The aim of the research is improving personal and social safety of a person through improving microclimate conditions in consideration of modeling thermal conditions in the premises. Methods of the research: analysis of theoretical and experimental works with scientific generalization; mathematical modeling; experimental exploration of radial heat exchange of a human body with indoor environment of the premise and its influence on the microclimate characteristics; processing experiment results with the methods of mathematical statistics on the computer. Theoretical and practical results: this is the first case when as a result of held research of the process of heat exchange between the surfaces in the premises and a human body there were established the regularities of distribution of radial heat exchange on a human body; on the basis of theoretical and experimental research there was offered the criterion of estimation of the amount of radial heat flow which comes into or out of a human body, that makes possible to estimate microclimate in existing premises and on the stage of their projecting; there was firstly developed the mathematical model where dependence of radiation between flat surfaces (walls) and the elliptic cylinder (human body) was received, that makes possible to estimate heat exchange between a human body and surrounding surfaces more correctly; there was firstly developed and built the analogue model which makes possible to held the exploration of radial heat exchange and its direction vector between the objects and a person in any spot of the premises area; there was improved the technology of all-year-round support of necessary microclimate characteristics of the premises on the base of absorbing heat converter with usage of renewed energy; optimization of work characteristics of the absorbing heat converter was held on the mathematical model; theoretical regulations which enable to estimate microclimate in existing premises and on the project stage were offered. Implementation level: the system of surface-developed heating of the premises implemented in the administrative building of the utility enterprise "Tramvai" (Dnieprodzerzhynsk) and office premises of the limited liability corporation "Atlas-Energo" (Dniepropetrovsk) in consideration of modeling radial heat exchange of a person with indoor environment of the premises as a part of microclimate optimization. Application sphere: building.
