摘要：Daily statistics on the volume of gas consumption and the average daily outdoor air temperature for a six-year period were adopted as an information basis for scientific research with the matter of studying the functioning and developing of the regional gas supply system. For the regional gas supply system, the type of structural fields “daily gas consumption – average daily outdoor air temperature” was determined and their constancy over time was proved. For structural fields, 4 temperature ranges are allocated and a system of characterizing indicators was proposed. The regularities of the formation of daily gas consumption from the average daily outdoor air temperature for the proposed temperature ranges were established, the sensitivity coefficient of the relative change in the daily gas consumption with a relative daily change in the outdoor air temperature was determined. Daily models of the gas consumption dependence on the outdoor air temperature was developed, smoothed by a moving average over 30 days for two temperature regions: 1 - the area of the connected state of the heating system, 2 - the area of the disconnected state of the heating system. The seasonal coefficient of gas consumption was assessed.
