GROUND OF RATIONAL HEAT SUPPLY SOURCE OF VNTU EDUCATIONAL CORPS

Abstract

Determining the design capacity of heating system of educational building VNTU conducted, multivariate analysis of sources of heat supply is conducted, the technical and economic comparison of the five options of heat supply sources based on renewable energy is made, the most economical source of heat is found. To reduce the cost of primary energy the options of a combined use of primary and renewable energy sources is considered. Evaluation of the payback period of the options allowed to choose rational combination heating system with a satisfactory technical and economic indicators. This system consists of the electric boilers with zone metering, accumulator tank and solar collectors.
