TECHNICAL AND ECONOMIC ANALYSIS OF THE SYSTEM LONG-WAVE INFRARED HEATING IN DIFFERENT TYPES OF BUILDINGS

Abstract

The paper presents the calculation of energy costs for heating buildings with three different heating systems, in order to determine the feasibility of using long-wave radiant heaters. The current rules of energy certification of buildings and related state standards of Ukraine were used as the calculation method. A technical and economic analysis was carried out, thanks to which savings from the transition to a radiant heating system in residential, public and industrial buildings located in the same weather environment were determined. The feasibility of radiant heating systems beyond the usual scope of use, namely in residential buildings, which make up the majority of all heating structures in Ukraine, and small architectural forms, such as, for example, modular buildings of retail establishments, public catering, etc., has been studied and provided. Bilux electric infrared long-wave heaters were chosen as the main research system. Competing systems are a water two-pipe system with free-flowing radiators and electric wall convectors. The key difference between traditional water heating systems, from the point of view of calculating energy consumption, is determined, which is the absence of losses in pipelines. It is justified that radiant heating systems are more appropriate in buildings with a floor height of more than 4 meters. It has been proven that in buildings of smaller volume, the cost reduction is also quite significant.
