“…In the case of internal insulation of the enclosing structure (before the structural layer), it is intuitively clear that the amount of accumulated heat by the most heat-intensive structural layer cannot equal the value obtained with classical external insulation (after the structural layer), which is also confirmed by the results obtained in [19]. Indeed, the value of the relative excess temperature of the structural layer (formula (9), in the case of internal insulation, will be low. Consequently, the reduced heat capacity of an external multilayer enclosing structure with the internal insulation will be much less, compared to a similar enclosing structure with the external insulation (formula (8).…”

“…With an excess of heat, accumulation (accumulation) occurs, with a shortage, return. For the effective accumulation of heat/cold, provided that the internal air temperature is maintained within the normalized values, enclosing structures have been proposed, which include substances with a phase transition [4][5][6][7][8][9][10][11][12][13]. In the case of intermittent operation of heating (cooling) systems, the heat storage capacity is directly taken into account to improve the accuracy of calculations [11][12].…”

The method of calculating the cooling rate of a room when the heating system is turned off there is an important practical task. As a result of such calculation, the time within which the room will cool down to an acceptable temperature, is indicated. During this time, emergency brigades must restore heating in the building. The aim of the work is to provide some refinement of the existing fundamental calculation formula by taking into account additional factors affecting the cooling process of the room. These include: taking into account the time of the initial irregular cooling process, taking into account the heat storage capacity of internal enclosing structures and furniture or equipment in the room, consideration of the initial temperature conditions in external and internal enclosing structures when calculating their heat capacity. The proposed approximate engineering technique is verified by comparing the calculation results with the results of direct calculation by the numerical method of the non-stationary thermal regime of the room in the full statement.

Cold spray additive manufacturing (CSAM) is generally used to repair worn components and build complex on-demand parts by depositing metal powder layer-wise using compressed air. Previous studies on CSAM were focused on printing parameters, materials properties, and printed part mechanical performance. However, the energy consumption and environmental impacts of CSAM processes have not yet been investigated, which are essential factors for sustainable manufacturing. This study aims to investigate the carbon footprint of the CSAM process and compare it with conventional machining processes and other additive manufacturing. The life cycle assessment methodology was followed to calculate the carbon footprint of a pipe flange, considering rod or tube as a feedstock. Results revealed that the machined flange from the tube had the lowest CO2-eq emissions of 31 kg CO2-eq due to low rough machining energy consumption and scrap production, compared to the machined flange from a rod and a printed flange from powder. Moreover, the life cycle carbon emissions increased by 8% and 19% in case of the printed and machined flanges, with uncertainties of 4% and 9%, respectively, when changing feedstock CO2 emissions. From a regional perspective, the CSAM process was responsible for the lowest CO2-eq emissions in Tasmania and South Australia.
