Abstract
The most important problem in agro-industrial complex is the problem of energy saving. Increasing the energy efficiency of optical electro-technologies, which use optical radiation as a specific energy factor, seems to be a very science-intensive task. The Finite Ratio Method (FRM) was developed by Professor V.N. Karpov as a set of operations based on the analysis of energy consumption in static and dynamic processes. The method is an important tool for the analysis and optimisation of energy-technological processes, as well as for the development of energy-saving systems according to a single indicator of energy efficiency – the energy intensity of the process. The aim of the research is to adapt FRM for its use in irradiation plants with gas-discharge lamps. The methodology of FRM application for revealing the energy saving reserves provides 'marking' of the scheme, which consists in allocation of energy blocks corresponding to the stages of energy conversion. In the paper, two blocks are allocated for the circuit with a discharge lamp: ballast (conversion of total energy into active energy) and discharge lamp (conversion of active energy into light flux energy). Expressions for calculating the energy intensity of these blocks are presented. In the first series of experiments, the operation of the LB 40 type lamp with active, inductive and capacitive ballasts was investigated. In the second series of experiments the operation of the same lamp with inductive ballasts of ABI and UBI brands was investigated. Instantaneous values of current, voltage and luminous flux were determined using oscilloscope C1-82. The total power consumption of the circuit with the investigated ballast brands is 0.022 and 0.017 VA.Lm-1 respectively. The efficiency of replacing ABI ballast with UBI as an energy saving measure, according to FRM, is 26%. Thus, the possibility of using FRM to analyse electrical circuits with discharge lamps fed from ballasts of different brands is shown.
