Eco-Design Of Energy-Using Products Directive
The Ecodesign Directive (Directive 2009/125/EC) of the European Union establishes a framework to set mandatory ecological requirements for energy-using and energy-related products sold in all 27 member states. Its scope currently covers more than 40 product groups (such as boilers, lightbulbs, TVs and fridges), which are responsible for around 40% of all EU greenhouse gas emissions. The 2009 revision of the Directive extended its scope to energy-related products such as windows, insulation materials and certain water-using products. The ultimate aim of the Ecodesign Directive is that manufacturers of energy-using products (EuP) will, at the design stage, be obliged to reduce the energy consumption and other negative environmental impacts of products. While the Directive's primary aim is to reduce energy use, it is also aimed at enforcing other environmental considerations including: materials use; water use; polluting emissions; waste issues and recyclability.

Incandescent Lamp
An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating a filament until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eco-design
Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle. The idea helps connect scattered efforts to address environmental issues in architecture, agriculture, engineering, and ecological restoration, among others. The term was first used by Sim Van der Ryn and Stuart Cowan in 1996. Ecological design was originally conceptualized as the “adding in “of environmental factor to the design process, but later turned to the details of eco-design practice, such as product system or indivi ...

Electricity Consumption
Electric energy consumption is energy consumption in the form of electrical energy. About a fifth of global energy is consumed as electricity: for residential, industrial, commercial, transportation and other purposes. The global electricity consumption in 2022 was 24,398 terawatt-hour (TWh), almost exactly three times the amount of consumption in 1981 (8,132 TWh). China, the United States, and India accounted for more than half of the global share of electricity consumption. Japan and Russia followed with nearly twice the consumption of the remaining industrialized countries. Overview Electric energy is most often measured either in joules (J), or in watt hours (W·h). : 1 W·s = 1 J : 1 W·h = 3,600 W·s = 3,600 J : 1 kWh = 3,600 kWs = 1,000 Wh = 3.6 million W·s = 3.6 million J Electric and electronic devices consume electric energy to generate desired output (light, heat, motion, etc.). During operation, some part of the energy is lost depending on the electrical efficien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Saving
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable energy or energy with more efficiency). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings. Green engineering practices improve the life cycle of the components of machines which convert energy from one form into another. Energy can be conserved by reducing waste and losses, improving efficiency through technological upgrades, improving operations and maintenance, changing users' behaviors through user profiling or user activities, monitoring appliances, shifting load to off ...

Machine Tool
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, Boring (manufacturing), boring, grinding (abrasive cutting), grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or "wikt:freehand#Adjective, freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. The precise definition of the term ''machine tool'' varies among users. While all machine tools are "machines that help people to make things", not a ...

Industrial Furnace
An industrial furnace is a device used to provide heat for an industrial process, typically operating at temperatures above 400 degrees Celsius. These furnaces generate heat by combusting fuel with air or oxygen, or through Electricity, electrical energy, and are used across various industries for applications such as chemical reactions, cremation, Oil refinery, oil refining, and Glass melting furnace, glasswork. The residual heat is expelled as flue gas. While the term industrial furnace encompasses a wide range of high-temperature equipment, one specific type is the direct fired heater, also known as a direct fired furnace or process furnace. Direct fired heaters are primarily used in refinery and petrochemical applications to efficiently transfer heat to process fluids by means of combustion. Unlike other industrial furnaces used in metallurgical furnace, metallurgy or batch ovens, direct fired heaters are optimized for precise temperature control and high thermal efficiency ...

Fossil Fuel
A fossil fuel is a flammable carbon compound- or hydrocarbon-containing material formed naturally in the Earth's crust from the buried remains of prehistoric organisms (animals, plants or microplanktons), a process that occurs within geological formations. Reservoirs of such compound mixtures, such as coal, petroleum and natural gas, can be extracted and burnt as fuel for human consumption to provide energy for direct use (such as for cooking, heating or lighting), to power heat engines (such as steam or internal combustion engines) that can propel vehicles, or to generate electricity via steam turbine generators. Some fossil fuels are further refined into derivatives such as kerosene, gasoline and diesel, or converted into petrochemicals such as polyolefins ( plastics), aromatics and synthetic resins. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels is ty ...

High Efficiency Glandless Circulating Pump
A high efficiency glandless circulating pump is a component of a heating and air conditioning system that allows the system to perform with increased efficiency while significantly reducing the system's electrical usage. Description It is primarily composed of an electronically commutated synchronous motor (ECM) with a permanent magnet rotor. The ECM is a motor that converts a direct current (DC) from an electrical source into an alternating current (AC) which is sent to the motor itself, allowing for increased efficiency over standard AC motors. The permanent magnet rotor consists of an iron core, surrounded by multiple magnetic rare earth metals, and finally a metal sleeve that evenly spaces the magnets around the core, which helps to drive the motor. By utilizing multiple small improvements in pump-design technology such as a double pump in parallel system and variable controls, these pumps are able to run at about a 50% to 70% increased efficiency with up to an 80% decrease ...

Ventilation (architecture)
Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor effluents and pollutants. It can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of the indoor environment, or other objectives. The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or mixed-mode ventilation. * Mechanical ventilation is the intentional fan-driven flow of outdoor air into and/or out from a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), Exhaust ventilation systems, exhaust fans (which draw air out of a building and thereby cause equal ventilation flow into a building), or a combination of both (called balanced ventilation if it neither pressurizes nor depressurizes the inside air, or only slightly ...

Air Conditioning
Air conditioning, often abbreviated as A/C (US) or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature, and in some cases, also controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or through other methods, such as passive cooling and ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide Heating, ventilation, and air conditioning, heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners but use a reversing valve, allowing them to both heat and cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used in vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming increasingly common in cool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
