Why Direct Drive Backward Curved Plenum Fans?

AAON equipment has been designed and engineered for both performance and energy efficiency. From standard equipment designs to complex heating and cooling systems, AAON provides performance and energy efficiency solutions for virtually all applications. Fans are one of the most important components of any HVAC (Heating, Ventilating and Air Conditioning) system in terms of performance and energy efficiency.

Direct drive, backward curved plenum fans are the optimum choice for practically all commercial HVAC applications. The following information will show the many reasons why.

Gathering Existing Building Conditions for Performance Analysis when Documentation is not Available

Every day, buildings use substantial amounts of energy, water, and raw materials, creating a sizeable environmental footprint. The government mandates are clear: buildings must become more energy-efficient and environmentally friendly. Because you need to evaluate the performance of and proposed modifications for dozens – if not hundreds or thousands – of buildings, your review process must be practical, repeatable, and scalable. Building Information Modeling (BIM) provides the basis for such analysis.

100% Outside Air Dehumidification Methods

As consulting engineers and end users implement the ASHRAE 62 ventilation code, they are faced with selecting an appropriate method for dealing with moisture. This Bulletin will describe the basic options available when moisture must be removed from the outside air before that air is introduced to the space. Since all of the moisture removal methods described involve significant cooling of the air, the Bulletin will go on to explain and compare the reheat approaches that are available for each moisture removal method.

Airflow Measurement for HVAC Systems – Technology Comparison

The proper selection of airflow measurement devices can be critical to the performance of today’s state-of-the-art HVAC system. Many of the requirements and limitations of one technology are often mistakenly thought to apply to every other. Not all technologies result in equal performance, even when used under similar conditions. Accuracy and repeatability vary between technologies and are most dramatically influenced by installation location, airflow rates, and required system turndown.

CO2 Based Demand Controlled Ventilation
Do the Risks Outweigh the Rewards?

Today's HVAC designs emphasize energy conservation. Unfortunately, design strategies often loose focus on other core objectives which include occupant health, productivity and the long term integrity of the building structure. The widespread use of CO2 demand controlled ventilation is a widely used strategy that has sacrificed many of our core objectives in the name of "conservation".

Outside Air Intake Flow Control
Designing for ASHRAE 62.1-2004, LEED and Risk Management

Changes in LEED guidelines and ASHRAE Standard 62 have reinforced the concept of direct monitoring of outside air intake flow rates for continuous control. Unfortunately, recent trade journal publications are full of misconceived and misguided information for the consulting engineer, which often trivializes the importance of direct outside air flow monitoring and control.

Using Your HVAC System to Improve IAQ

In a joint 2000 report, Lawrence Berkley National Laboratory and the U.S. Department of Energy estimated that improving indoor air quality would yield up to $208 billion annually through decreased health care costs and improved productivity. The really good news is that these savings can be achieved with minimal investment and with technology that is readily available.

Fan Applications

There are many different types of fans and many applications in which they can be used. For an application to be successful and work as intended, the fan and system must be compatible both structurally as well as from a performance standpoint. This section outlines several generic fan applications and the major considerations relating to fan type, rating parameters and fan design. Please use this information as a part of the fan selection process.

Optimizing Dedicated Outdoor Air Systems

Bringing outdoor air into a building is vital for maintaining good indoor air quality. However, outdoor air can be very expensive to temper and, if not properly conditioned, can cause humidity problems for the building. Designers are increasingly finding that using dedicated outdoor air systems (DOAS) allows them to comply with ASHRAE 62.1 with an energy efficient and easily verifiable design. DOAS incorporates a dedicated unit to supply cooled, dehumidified outside air to the building in the summer and heated outside air in the winter. These types of systems are ideal for schools, dormitories, hotels, and assisted living facilities, to name a few.

Absolute Zero Net Zero Energy commercial buildings – an inspiring vision for today

Buildings are both a significant cause of and a potential solution to climate change and energy insecurity. In the United States, buildings consume nearly 40% of the country’s energy and are responsible for almost 40% of greenhouse gas emissions. That represents 8% of the world’s greenhouse gas emissions, an amount equal to the emissions from all of India.
