Development of air flow control device for industrial and social buildings of JSC Russian Railways

Introduction. The authors considered ways of reducing costs of building maintenance as a solution of one of the target tasks of the JSC Russian Railways. The air flow standards may be achieved with lower heat and electricity consumption through the use of energy efficient ventilation systems. Automated systems for controlling the flow of air supply and exhaust ventilation were observed. Analysis of the principle of operation of these systems allowed to develop a prototype of an innovative device and test it on various facilities of JSC Russian Railways, thereby achieving reduction of energy consumption.Materials and methods. Methods of field tests of ventilation system on a stand for filters to purify air entering passenger car space and field comparative tests at sanatorium of JSC Russian Railways were applied.Results. The feasibility of using air flow control devices of ventilation systems, comparative tests of which performed on production and social facilities of JSC Russian Railways, were scientifically proven, demonstrated reliable operation and stable savings in energy consumption, compared to the standard operating modes of ventilation.Discussion and conclusion. The results of the work enable to affirm that application of the developed prototype of the air flow control device in ventilation systems of production and social buildings of JSC Russian Railways would ensure reduction of energy consumption while maintaining normalised parameters of the air volumes passing through the air ducts.
