Savchenko I. Perfection of methods of maintenance of the normalized parameters of radiant irradiation on the workplaces of machine-building enterprises.

The thesis is devoted to the vital activity increase in the conditions of The thesis is devoted to the vital activity increase in the conditions of industrial premises by means of determining the influence of systems with gas infra-red emitters (GIE) on the microclimate parameters and the degree of man - operator radiation exposure. The mathematical model of heat balance of industrial premises having GIE has been improved regarding the radiant-convectional heat exchange between the surfaces of non-load-bearing constructions, the GIE radiative surfaces and a man-operator as well as geometrical parameters of industrial premises. The necessity of taking into consideration in the mathematical model of determining the required heat capacity of IR emitters the influence of heat radiation absorption, an altitude of their suspension, global planning decisions, an optimal multiple of air exchange, an air dust and humidity has been grounded resulting in more exact calculation of the microclimate parameters of industrial premises. The new conception of physical peculiarities of the process of infra-red irradiation influence on the human organism has been obtained which allows to improve its existing model with a normative parameter which makes an impact on the microclimate state and presents a value of the flow density considering a wave length of generative irradiation that supplements its integral characteristic with a spectral one and represents the stated process in full. The algorithm of modeling and the computer programme which has a dialogue scheme, analyses the input data, sets values of the required coefficients, deduces all possible variants of decisions and on the basis of the building and planning specific character determines the angle coefficients of irradiation and graphic displays of the built diagrams of density of the total irradiation have been worked out.
