The integrated waste energy recovery system (IWERS) recovers heat from bakery ovens in supermarkets and other commercial facilities to heat domestic hot water, resulting in energy savings. This article presents a thermoeconomic analysis of the system's operation in a supermarket over the course of 1 year. The study shows that exergy destruction in IWERS is directly proportional to ambient temperature. During the hottest months of the year, IWERS experiences a 4% decrease in exergy performance, while the exergy unit cost of the product increases by up to 4.2%. Additionally, the steam condenser is responsible for the highest relative exergy destruction, reaching almost 45%. Moreover, the addition of equipment upstream of the process increases the exergy cost of production due to the destruction of exergy in the equipment. These results provide valuable information with important implications for energy efficiency, economic savings, and sustainability. Improving system efficiency would generate substantial benefits in energy savings, economic savings, and environmental impact for all commercial and industrial establishments that use bakery ovens.

“…Climate change, environmental pollution, and energy security have emerged as global challenges, posing severe threats to human survival and development [5,6]. In such a milieu, the globe has reached the consensus to develop a low-carbon economy; it is also one of China's critical measures to address climate change issues [7,8]. Presently, China is amidst rapid urbanization and industrialization, making the industry the chief consumer of energy and producer of carbon emissions.…”

Global climate change imposes significant challenges on the ecological environment and human sustainability. Industrial parks, in line with the national climate change mitigation strategy, are key targets for low-carbon revolution within the industrial sector. To predict the carbon emission of industrial parks and formulate the strategic path of emission reduction, this paper amalgamates the benefits of the “top-down” and “bottom-up” prediction methodologies, incorporating the logarithmic mean divisia index (LMDI) decomposition method and long-range energy alternatives planning (LEAP) model, and integrates the Tapio decoupling theory to predict the carbon emissions of an industrial park cluster of an economic development zone in Yancheng from 2020 to 2035 under baseline (BAS) and low-carbon scenarios (LC1, LC2, and LC3). The findings suggest that, in comparison to the BAS scenario, the carbon emissions in the LC1, LC2, and LC3 scenarios decreased by 30.4%, 38.4%, and 46.2%, respectively, with LC3 being the most suitable pathway for the park’s development. Finally, the paper explores carbon emission sources, and analyzes emission reduction potential and optimization measures of the energy structure, thus providing a reference for the formulation of emission reduction strategies for industrial parks.

“…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.
