  • The Effectiveness of Combined heat and Power Solar Water Heating Systems

    Abstract: Solar water heating in residential and commercial buildings is often provided by integrating a large number of domestic thermosyphon solar water heaters. The economic effectiveness of solar Domestic hot water heating systems depends mainly on its types and configurations. Thereupon in this paper, simulation models have been presented for the modeling of thermal and electrical ...


  • Thermodynamic analysis of a geothermal district heating system

    Thermoeconomic analysis is considered a useful tool for investigators in engineering and other disciplines due to its methodology based on the quantities exergy, cost, energy and mass. This study deals with an investigation of capital costs and thermodynamic losses for devices in the Balcova Geothermal District Heating Systems (BGDHS). Thermodynamic loss rate-to-capital cost ratios are used for ...

  • Domestic heating systems are more efficient with Scalewatcher

    In hard water areas plumbing, hot water systems and appliances quickly become encrusted with limescale resulting in increasing energy bills and the early renewal of boilers and appliances.  The award-winning, patented, Scalewatcher water-conditioner, from Scalewatcher North America, offers a simple and permanent solution to limescale thereby reducing energy bills and making heating systems ...

  • Ground Source Heat Pumps

    In many buildings Ground Source Heat Pumps (GSHPs) provide an efficient solution for heating and cooling. Using low temperature latent heat which exists naturally below ground, GSHPs provide solutions by harvesting and transferring this energy for the benefit of the built environment. It is important to understand the feasibility of GSHP prior to designing a system. This guidance note has been ...

  • Thermal characteristics in latent heat energy storage system using paraffin wax

    An energy storage system has been designed to study the heat transfer characteristics of paraffin wax during melting and solidification processes in a vertical annulus energy storage system. In the experimental study, three important issues are focussed. The first one is temperature distribution in the phase change material (PCM) during the phase change processes. The second one is the thermal ...

  • Much light, little heat efficiency

    Energy efficiency in the US is much light and little heat – literally.  Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.  “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the ...

  • Case study - Heat exchanger retrofit

    Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Geothermal Heat Pump (GHP) - Case Studies

    Case Study: “GHP schools used approximately 26% less source energy per square foot of floor area,” according to an evaluation of Lincoln, Nebraska schools by the Department of Energy. The report concludes that the schools using GHP technology “outperform others in the school district.” Case Study: Annual electrical consumption in Fort Polk ...

  • Small-scale heat and power at B.C. mills

    Fred Scott introduced the B.C. Bioenergy Network (BCBN) as an alliance between Pristine and Nexterra Energy Corp. BCBN is a network of 15–20 individuals, with 10 MW power plants located across B.C. at mill operations in forest communities. Nexterra has developed a proprietary gasification technology that “takes wood waste material and [produces] clean burning synthetic gas or syngas,” Scott said. ...

  • Opening markets for CSP – the industrial heat application

    Heavy industry can be a viable secondary market today for CSP producers, but questions remain on whether start-up costs are justifiable for industrial users, and how reliable CSP can be for processes that can't pace production by the sun. Solar thermal heat implies steam, and industries that need steam include refining, food processing, wood-working, desalination and chemicals, among others. ...
