Abstract

Objective. The main purpose of the study is to analyze and classify the existing types of non-traditional renewable energy sources that can be used in the form of an air pre-treatment unit for passive saving of energy consumption by ventilation systems of residential buildings. Such sources include soil heat exchangers, which either transform the scattered thermal energy of the soil into relatively high-potential heat with subsequent use for the needs of the ventilation system, or use it directly for passive preheating in winter and/or precooling in summer of the supply air of the ventilation system, which enables reduce energy costs for maintaining acceptable sanitary, hygienic and meteorological parameters of the premises. Methods. The results presented in the article were obtained using methods: generalization of the results of previous studies, complex analysis, logical-structural analysis, scientific-analytical analysis, etc. Scientific novelty. The research makes it possible to single out and systematize the existing types of non-traditional renewable energy sources, namely soil heat exchangers, which can be used as an air pre-treatment unit (heating and/or cooling) in the ventilation systems of residential buildings. Practical significance. The analysis of existing types of non-traditional renewable energy sources, namely soil heat exchangers, which can be used for the needs of ventilation systems of residential buildings, and their classification by structural features will help specialists in the design or reconstruction of ventilation systems of residential buildings to reduce energy consumption by the ventilation system for pretreatment ( heating and/or cooling) of supply air. The results. The types of soil heat exchangers, which have gained the most distribution as a unit of air pretreatment of the ventilation system, are given, and their classification by structural features is developed. The article will be useful to designers, engineers, builders and everyone who is interested in the implementation of non-traditional renewable energy sources for the purpose of passively saving energy consumption by ventilation systems of residential buildings
