Mathematical Modeling of the Annual Consumption of Gas-Air Mixture on the Basis of Technical Butane for Household Needs of Individual Residential Buildings

Increasing share of private house building in the suburban zone of large cities, neighborhoods with townhouses, and suburban settlements with permanent residence of people requires intensive construction of engineering systems, including gas supply systems. The speed of providing built-up areas with pipeline network gas does not always keep up with the pace of housing construction, it is not economically feasible and may not be possible due to the relief features of the terrain. In this case, one of the possible sources of gas supply is autonomous gas supply systems based on gas-air mixtures. The most economically attractive one is the mixture of butane and air. At the same time, the recommendations for the determination of gas consumption regimes based on gas-air mixtures are very limited in the literature. Development of reasonable recommendations for determination of gas and air mixture consumption will ensure correct selection of gas supply elements, which causes reduction of cost of autonomous gas supply systems in general and will increase their attractiveness to the consumer.

A mathematical model for determination of annual consumption of gas-air mixture on the basis of technical butane for municipal and household needs is proposed, taking into account climatic features of the terrain, the aspect ratio of the object under study, the degree of glazing of the building facades, and the height of the floor. On the basis of the correlation analysis of mathematical modeling results, the dependences for determination of consumption of gas-air mixture for municipal and household needs of the building are proposed.
