The use of results of indirect measurements in accounting problems of general house needs of hot water consumption

Abstract

With the introduction of the new rules for calculating the general house needs in 2017. The transition to full payment of all energy resources consumed by residents of apartment buildings using general household metering devices raised many questions related to the accuracy of the calculation. It is well known that in the absence of automated systems for apartment-based metering in residential buildings and incomplete equipping of apartments with individual appliances, situations often arise when the total house volume of utilities significantly exceeds the total consumption of apartments in the house. The reasons for this excess imbalance may be different. The most likely of them are leaks in pipelines, illegal connections to networks, inconsistency of the standard values with actual consumption. Based on practical material, this article considers another one of the most significant factors affecting the general house needs. This is indirect measurement method when taking into account the general house needs of hot water. The article proposes a method for improving the accuracy of indirect measurements used for commercial accounting of hot water consumption. The method is based on the determination of the amendment to the results of measuring the difference in flows, allowing to evaluate the effect of errors of flowmeters and take this factor into account when further calibrating flowmeters. Consideration is conducted on the example of accounting for the consumption of hot water in a particular residential house.
