Snow And Ice

In winter, for our own safety, as well as for the comfort of the user, we are obliged to remove or mitigate the defects related to the accumulation of snow and ice on flat surfaces, such as: pavements, stairs, driveways, parking lots, roofs, squares, or sports fields. Snow and ice from these surfaces can be removed by a variety of methods. Chemical, mechanical, or heating methods are most often used. Mechanical and manual methods cannot always be used. They also often do not allow the complete removal of snow and ice from the surface. In chemical methods, the chemicals used can have a negative impact on the environment and the surface itself. Heating external surfaces using electric heating cables or liquid-filled pipes is one of the safest and most effective ways to remove snow and ice from the available methods. The article presents a technical concept of a car park heating system with the use of various heating systems. The main thesis of the work is the possibility of using heating systems to maintain the quality of external parking spaces in winter. The authors tried to prove that it is possible to use a number of heating systems based on commonly known energy carriers for this purpose. The concept was made for the conditions prevailing in Poland. The systems were compared in financial and ecological terms. The following systems were analyzed: electric heating, heating with the use of a heat pump with a vertical ground heat exchanger, and liquid heating with various heat sources (including heat from the district heating network, hard coal boiler, biomass boiler, fuel oil boiler, natural gas boiler). From a cognitive point of view, it was interesting to examine whether the proposed installation with a heat pump is technically feasible and economically and ecologically justified.

Snow And Ice

In winter we are forced to eliminate or mitigate the disadvantages associated with the accumulation of snow and ice on sidewalks, steps, driveways, roofs, squares, sports fields. There are many ways to remove snow and ice from the considered surfaces, including chemical, mechanical or use of a heating installation. Mechanical or manual methods do not always allow to completely remove snow and ice, while chemicals often have a negative impact on the environment. The most effective is the use of an electric or liquid heating installation. The article presents the results of technical analysis for a maneuver area heating system for driving training lesson using a heat pump with a ground heat exchanger, as well as financial analysis of its application in the established conditions. The literature lacks information on this subject, so it was interesting to investigate whether the proposed installation is technically and economically feasible.

To transport highly viscous crude oil efficiently through pipelines, some electric heating systems have been conventionally used. But they include heating cables or tubes, which are troublesome in submarine pipeline construction. A new electric heating system without a cable has been developed and is applicable to long-distance submarine pipelines. This system has a coaxial steel pipe structure, using the pipes as a heater by applying AC current to this coaxial circuit. In this paper, electromagnetic analysis on this system, experimental study using a 30-m length test pipeline, and mechanical tests on the electric insulating structure of the system are described.

Significant Difference

High electricity consumption, carbon dioxide (CO2), and elevated noxious gas emission in the global livestock sector have a negative influence on environmental sustainability. This study examined the effects of a heating system using an air heat pump (AHP) on the energy saving, housing environment, and productivity traits of pigs. During the experimental period of 16 weeks, the internal temperature was found to be higher (p < 0.05) in the AHP house than in the conventional house. Moreover, the average electricity consumption and CO2 emission decreased by approximately 40 kWh and 19.32 kg, respectively, in the AHP house compared to the house with the conventional heating system. The average NH3 and H2S emissions were significantly lower in the AHP house (p < 0.05) during the growth stages. The AHP and conventional heating systems did not have a significant influence (p > 0.05) on the average ultra-fine dust (PM2.5) and formaldehyde level fluctuations. Furthermore, both heating systems did not show a significant difference in the average growth performance of pigs (p > 0.05), but the weight gain tended to increase in the AHP house. In conclusion, the AHP system has great potential to reduce energy consumption, greenhouse gas (GHG) emissions, and noxious gas emissions by providing economic benefits and an eco-friendly renewable energy source.

The traditional biogas heating system has the disadvantages of a low energy efficiency ratio and high energy consumption. In this study, a solar-untreated sewage source heat pump system (SUSSHPS) was developed for heating a 12 m3 multiphase flow digester (MFD) in Suining, China. To investigate the operating effects, two modes were defined according to the solar fractions in different regions. On the basis of experimental data, thermodynamic calculations and operating simulation analysis were performed, and the solar collector area (Ac) and the minimum length of the sewage double-pipe heat exchanger (lmin) for the two modes were calculated. The results indicated that the Ac and lmin of mode 2 were larger than those of mode 1 at different solar fractions. Additionally, the results suggested that mode 1 can be used at a solar fraction of <0.33, and mode 2 can be used at a solar fraction of >0.5. Moreover, a comprehensive evaluation of different biogas heating systems was performed. Two evaluation methods were used for modeling calculations, and the results of the two methods were consistent. The SUSSHPS had the largest comprehensive evaluation value among the four systems. The proposed SUSSHPS can play a significant role in improving current biogas heating systems and promoting the development of biogas projects.

This paper discusses the use of modern and effective heating systems, using fossil fuels and renewable energy sources on the example of a comparative analysis of a gas boiler and heat pump for a single-family building. The aim of the work was to conduct a comparative analysis of heating systems in terms of energy, economy and ecology. The concepts of heating systems based on a gas boiler and a heat pump are proposed. An economic analysis based on the LCC and ecological method was carried out, related to the equivalent emission, in order to compare the degree of environmental nuisance of the proposed heat sources. For the building in question, a more advantageous solution was the use of a system based on a condensing gas boiler. The economic analysis shows that in the assumed life cycle (20 years), the total cost for a heating system based on a gas boiler is lower than in the case of a heat pump by 11%. Also, the initial costs in this variant are lower by nearly half compared to the heat pump system. Environmental analyzes have shown lower annual emissions of pollutants and a 6-fold lower equivalent emission for a gas-fired heating system.

Analysis of three-temperature heating system has revealed the apparent advantages and disadvantages that the combination of thermodynamic systems has in future development with respect to environmental and economic issues. Three-temperature heating systems consist of a heat engine and a heat pump, thus enabling maximum use of the primary thermal source for heating buildings. It seems that the combination of a Stirling engine, or a similar heat drive, with a heat pump is suitable. In order to analyse the effectiveness of such a system, a comprehensive calculation procedure is used as follows: its basis lies in accounting for all types of energy and their relationship to the original natural resource. The present study aims to point out that the combination of a Stirling engine and a heat pump is a useful solution due to the fact that it has the most favourable resultant economic impact in comparison to the use of a diesel, four-stroke gas or the most commonly used electric drive.
