Innovations in Industrial Waste Heat Management - 1 views

  • Industrial waste heat management has seen rising levels of importance due to volatile fuel prices and also regulations to maximize energy conservation. As such, industries have started recognizing the necessity and advantages of industrial waste heat management. Till recent past much importance was being paid to recovering waste heat and reusing it as thermal energy. But now the focus is on new methods of waste heat recovery which convert even low grade waste heat into other forms of energy with increased feasibility. Low grade waste heat recovery, which has slowly been gaining prominence is expected to be a major driver for research in the future. This research service report presents analysis on current technology capability and expected future trends in technology adoption for industrial waste heat management. Analytical Hierarchy Process (AHP) was used to evaluate the application potential in the five most energy intensive industries – Cement, Oil and Gas, Steel, Pulp and Paper, and Glass to identify the industry with greatest future application potential. Based on inputs from technology developers and from the predicted market scenario, an evaluation was done.

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

Johnson Controls introduces air conditioners with MicroChannel technology. -REFRIGE.COM... - 0 views

  •  
    Johnson Controls, a global leader in building efficiency, announced the new LX Series of air conditioners and heat pumps by York, its leading air conditioning, heating, refrigeration, and ventilating company. They feature a MicroChannel coil with enhanced heat transfer characteristics, enabling them to achieve the desired performance levels with less coil surface area than competitive condensers and up to 50 percent less refrigerant. The units are available with environmentally friendly R-410A refrigerant as well as R-22. 14.5 SEER LX Series air conditioners use a compressor blanket and swept-wing fan blade for quieter operation. 15+ SEER can be achieved when the air conditioner is matched with a variable-speed air handler or gas furnace. A fully louvered steel coil guard, corner posts and a polymer mesh protect the condensing coils from damage. The unit's heavy-duty cabinet is made of powder-painted steel that resists corrosion and rust creep.\n\n\n\n\nIn addition, the MicroChannel coil offers better galvanic corrosion resistance than conventional coils. In testing, the coil withstood 7,000 hours of salt spray with a higher success rate than conventional coils at just 1,000 hours, making the units particularly desirable for seacoast applications, reveals the company's press release.\n\n

Energy Efficency In Hospitals - Cogeneration - 0 views

  •  
    "Because of their specific heat and electricity consumption, hospitals are particularly suitable for cogeneration. A characteristic of hospitals is that there is a constant demand for heat all year round, for e.g. hot tap water and sterilisation. This constant heat demand profile has a favourable effect on the number of hours at which the cogeneration unit can operate at full load."

Heat Roadmap Europe 2050 - 0 views

  • In this pre-study, ambitious but realistic growth rates are assessed for district heating in the EU27 until 2050. The methodology is a combination of hour-by-hour energy modelling of the EU27 energy system and mapping of local conditions. The study finds that deliveries from district heating in the EU can grow by a factor of 2.1 until 2030 and by a factor of 3.3 until 2050.

Wonder stuff: Heat scavengers promise energy bonanza - 0 views

  • Reclaim even a small amount of that lost heat as electricity, and that would massively boost energy efficiency. Thermoelectric materials allow us to do just that, by coaxing a current from a temperature difference. Wrap a thermoelectric substance around your car's exhaust, and its waste heat could power the electrics. Incorporate thermoelectric elements into a refrigerator, and heat extracted from its interior could power it

Recently Discovered Nanocoating Makes Heat Transfer Happen Much Easier - 0 views

  • The action of cooling things down plays a critical part of any mechanical or electric system, because the inevitable heat, produced by friction, is the number one cause of almost instant failure. So far, different methods that cool systems have been discovered, but not to the extent of performance that engineers dream of building their computers or mechanical devices (cars, for example). Oregon State University researchers, led by Terry Hendricks, have discovered a method of applying a nanostructured coating that could make the heat transfer more easily. Their findings have been published in the International Journel of Heat and Mass Transfer, and they also filed a patent for them.

Striving for Super Efficiency - Air Conditioning, Heating & Refrigeration NEWS - 0 views

  •  
    Long ago, the industry determined that the combination of copper tubing and aluminum fins provided the most efficient transfer of thermal heat in condenser coils. Manufacturers of residential units are not necessarily on that same page - or that line of thinking - today. Most manufacturers, if not all, are revising, have revised, or continue to revise their outdoor coil construction. One of the main objectives, of course, is to increase heat transfer efficiency, as energy efficiency is high on every homeowner's wish list. In the end, each manufacturer believes it has engineered and/or perfected - at least up to now - the most-efficient coil design. Some, like Goodman Manufacturing, have made changes as a direct result of the efficiency offered from R-410A refrigerant.

Solar Cooling - 0 views

  •  
    Compared to other solar energy applications, solar cooling is a relatively new, but growing, technology. Many projects using the technology are still for the purposes of demonstration only, but a growing number of systems are being implemented all over the world for conventional use. In order to give an insight into this innovative technology, detailed information about the possible technical applications of solar cooling systems is provided in this section.\n\nPassive solar cooling, based on bioclimatic strategies such as sun protection using natural screening devices or increased cooling by using ponds or water basins o the roof or close to the external walls, is widely applied and should be the first step to take in cooling a building. Such measures are easier and less costly to implement, they decrease the need for additional cooling and, therefore, for additional energy demand (and also for investment). Sufficient insulation of the building also decreases the need for cooling, as well as for heating.\n\nIf the outcome of these measures is not sufficient in itself, a solar assisted cooling system may be an intelligent solution. In solar assisted cooling systems solar heat is used to drive the cooling process for air conditioning in buildings. Instead of using electricity, free solar thermal energy is used for cooling through a thermal-chemical sorption process.\n\n

    Thermoelectric bracelet that helps people maintain a comfortable body temperature takes home $10,000 from MIT's annual materials-science design competition. The "watch" part of the prototype actually consists of the team's custom copper-alloy-based heat sink (a component that lowers a device's temperature by dissipating heat). Attached is an automated control system that manages the intensity and duration of the thermal pulses delivered to the heat sink. Integrated thermometers also measure external and body temperature to adjust accordingly.
