  • Solar heat assisted solid desiccant dehumidifier saved over 30% electricity for air conditioning in Kish Island

    Thermal energy exploited from solar heater panels has been recently assisted in a desiccant wheel air conditioning demonstration project in Kish Island, Persian Gulf, Iran. “This demonstration unit was completed in late 2008 and successfully tested afterwards” said Pejman Izadkhast, M.E., the project manager, “simple solar water heating panels by total surface of 48m2 were utilized to supply ...

  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • Effect of outdoor air parameters on energy consumption with heat-pipe used in air-handling unit

    A study was carried out to investigate the influence of outdoor air parameters on energy-saving capability in an air-conditioned building with heat-pipe used in air-conditioning processes. The study indicates that the sensible heat recovered by heat-pipe is related to the outdoor wet-bulb temperature and to the temperature difference of outdoor dry-bulb and wet-bulb temperatures. The lower the ...

  • From air conditioning to urban planning, defaults and standards create dysfunction by design

    How can we stop outdated assumptions from forcing us to waste? Personal heaters are a summer survival tool for many office workers chilled to the bone by hyperactive ventilation systems — an act of self-defense against an epidemic of overcooling that is wasting energy and confounding comfort in not only offices but also large shops, schools and other buildings. An audit ...

  • Meeting compliance with process aerators - Equipment improves process, saves energy in nation’s oldest city

    St Augustine, Fla., founded by Europeans in 1565, is the nation’s oldest city. The city is a perfect blend of aging gracefully while staying at the forefront of environmental protection. When this pristine community started experiencing problems with its wastewater treatment system, they found a solution using Aeration Industries’ Aire-O2 Triton process aerators and mixers. The ...

  • Energy research and the cobbler’s children

    Scientific research has brought us products that offer greater energy efficiency. But is research, itself, energy efficient? Evan Mills, staff scientist with the Lawrence Berkeley National Laboratory, raises this question and points out what may be a largely untapped market for energy efficiency companies: research labs. (See Environmental Science & Technology, ...

  • CMR consultants educates school on water savings - case study

    Introduction St. Helen’s is an independent girls’ day school of more than 1,100 students aged from 3 to 18. Located in Northwood, St Helen’s spans 23 acres, with over 20 utilised buildings. Energy and water management and efficiency is important to St Helen’s in order to keep all overheads to a minimum, ensuring value for money to their pupils and families. ...

  • Does Innovation in Indoor Air Quality Involve a Paradigm Shift?

    Instead of diluting indoor air with compromised outside air, consider removal and destruction of pollutants as part of the HVAC system. Purifying indoor air reduces the level of ventilation required, thereby lessening the energy used to condition outside air. This results in energy savings, increased building value and improved occupant productivity through enhanced indoor air ...

  • Energy efficient aeration of wastewaters from the pulp and paper industry

    More than 50% of the electrical power needed to treat pulp and paper industry effluents is used for aeration in biological treatment stages. A large share of the oxygen that passes through the wastewater is not consumed and will be found in the off-gas. Energy can be saved by aerating under conditions where the oxygen transfer is most efficient, for example at low concentrations of dissolved ...

  • Optimizing air flows to aeration basins – Case Study

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then ...
