Seismically Certified AAON HVAC Equipment
After an earthquake or seismic event, buildings containing essential services must be able to remain operational. Seismic certification of HVAC equipment provides assurance that the equipment will not only survive the earthquake, it will remain online and functional. Seismically certified HVAC equipment allows consulting and specifying engineers to meet the strictest seismic building codes, quickly and easily, without the delays of additional certification testing. Seismically certified HVAC equipment allows building owners to protect their investment.
Advantages of Using Integrated Thermal Controls Versus Third-Party Controls
Data center managers have many choices when choosing thermal controls, either those that come pre-installed and integrated with cooling units, or third-party controls requiring installation on units and additional integration programming. Emerson Network Power believes that using thermal controls that come integrated with cooling units helps ensure fast, trouble-free, and efficient thermal management and easier integration to building management systems (BMS). In contrast, some of the biggest mistakes we have seen in the thermal controls arena have resulted from using third-party controls requiring complex programming and integration to units and the BMS.
Greenheck Project Profile: Wausau Curling Center, Wausau WI
The sport of curling is a strategic game like chess, with an element of skill and experience. Played on ice in an indoor controlled environment, temperature and humidity are critical to setting ice speed and the amount of “curl” the stone will incur. Another design challenge was dealing with the variable loads without over-ventilating which would lead to extremely high utility bills.
Preventing Arc Flashes
This free white paper from Rittal looks at the dangers and causes of arc flash and what can be done to prevent it. Arc flash is the explosive release of energy triggered by a phase-to-phase or phase-to-ground short circuit. When an arc flash event occurs, air becomes a conductor and carries electric current with potentially lethal results for workers and equipment. Knowledge is power and workplace safety is a planned solution, not a lucky accident. Keep your plant or facility and employees safe via this complimentary white paper from Rittal.
Clarification on the Calculation of Boiler Efficiencies: A UNILUX Perspective
Efficiency is the name of the game today, and the boiler world is no exception. If you can squeeze half a percent of efficiency out of a boiler it can amount to enormous cost savings on an annual basis. So, it should come as no surprise that finding creative ways of calculating efficiency when selling a product has become a common practice. However, there are those methods that have a logical precedent behind them (choosing between the heat loss method and the input-output method), and there are those methods which are in fact misleading and incorrect.
