Comparative analysis of ukrainian and european code of heat capacity calculation

Purpose. Wile considering the general trend towards the harmonization of Ukrainian and European approaches in the field of heat supply is practically useful comparative analysis of certain domestic and European regulations and the rules of calculation of heat supply. Methodology. Proposed a comparative analysis of some Ukrainian and European normatives and rules for calculating the power of heating systems based on the studying the normative documents, reference and scientific and technical literature. The translation of the provisions of European standards made not literally, but in aim to convey the meaning of the requirements more accurately. Findings. It was found that even through the similarity of the general principle of Ukrainian and European rules for calculating power heating systems, differences in detail steps of calculation, the notation values, units of certain factors took their place. A greater detail of European settlements explained by predominance of energy efficiency requirements. Originality. There is a comparative analysis of the further development of existing standards on engineering systems of buildings with EU standards, taking into account local regulations, which came into force in the last 3-5 years. Practical value. The analysis results of EN 12831: 2003 can be used in the calculations before the Ukrainian standard, which is being developed with the degree of compliance with the European ?IDT? (identical). Comparative analysis promotes understanding of Ukrainian specialists in the field of heating with European colleagues.
