Implementation of eco-safe mobile sources

Abstract

Purpose. Introduction of alternative energy supply in urban private homes based on the use of environmentally safe mobile sources during emergencies of a natural, man-made and military nature Methodology. The research methodology included: analysis of the features of heat losses of buildings through their enclosing structures in emergency situations; determination of the heat loss capacity of a typical building and the expected heat conservation after its thermal modernization; calculation of the capacity of alternative environmentally safe mobile energy sources required for economical provision of private homes with heat and hot water in emergency situations. Findings. The peculiarities of heat consumption by residential buildings in economic conditions of emergency situations were revealed. Heat losses of a typical house of the urban private sector were determined. It has been shown that its heat conservation levels are significantly lower than modern standards, therefore there is a need for preventive thermal modernization in view of its alternative energy supply in emergency situations. It has been established that after the recommended insulation of the house, the expected heat loss will decrease to 3.42 kW, and the total thermal resistance of its enclosing structures will increase to 1.512 m2×K/W, which allows the use of a pair of environmentally friendly heat pumps: "air-to-air" and "air-to-water" for heating the house Scientific novelty. It was found that the heat loss of a typical private house is expected to be high, which is due to the total thermal resistance of its enclosing structures being almost 7 times lower than the current norm. Moreover, the facade walls and roof let in up to 70.8% of the heat. Therefore, the authors propose energy-saving energy supply of the building in emergency situations based on environmentally safe mobile sources after the preventive thermal modernization recommended by the authors. Practical significance. The results of the study of the levels of heat conservation of one-story houses in the urban private sector allow for economical alternative heat supply through the use of portable environmentally friendly heat pumps: "air-to-air" and "air-to-water", powered during emergencies by a gasoline generator that will operate in nominal mode with minimal emissions of environmentally unsafe substances into the atmosphere.
