The American Aldes ZRT-2 regulates each zone in a central exhaust and supply ventilation system without the need for individual fans or expensive controls. It can serve both low-flow IAQ ventilation or on-demand high-flow spot ventilation on a single central fan system. It is pressure independent, which means it automatically regulates airflow to compensate for fluctuations in duct pressure.

The ZRT-2 can be used in both commercial and residential applications, and it is suitable for new construction and retrofit projects. End users benefit from accurate ventilation, which directly correlates to energy savings and improved indoor air quality. The continuous low-flow regulator ensures that the space is neither over- nor under-ventilated, while the optional boost provides on-demand ventilation when the user requires it. Since the ZRT-2 operates so quietly, users will notice the fresh air – not a noisy fan. In residential applications, ZRT-2s can reduce the number of exterior vent penetrations.

The ZRT-2 introduces flexibility and dynamic control to central ventilation systems. With its grille, register box, control damper, and flow regulator(s), the ZRT-2 is a turnkey solution. It is available with 4″ or 6″ collars; it provides continuous low-flow ventilation of 10-60 CFM; and it is capable of providing boost ventilation ranging from 50-175 CFM. The product installs easily, requires little-to-no maintenance, and is a lasting, cost-effective solution.

Heat Recovery Ventilation Study to Aid Poultry Farmers

Crowder College MARET (Missouri Alternative and Renewable Energy Technology) Center instructor, Rebekah Starkweather, is working on a winter ventilation project for broiler houses to help reduce energy use during the winter months.

The US Department of Agriculture lists 145,615 poultry farmers in the United States with an average of four broiler houses per farmer. Propane is the common fuel used for heating in temperate climates with a typical broiler house consuming $7000 to $10,000 a year. Rapidly rising fuel costs are forcing farmers to look for new approaches to help keep their operations profitable. Fuel use represents the largest percentage of energy costs during the winter. Heat loss through the fan ventilation system is most prevalent in broiler houses. The HRV system will recover heat in the ventilation air and complement the existing ventilation system.

This collaborative effort is researching a new ventilation approach to provide area poultry growers with an opportunity to decrease their heating expense and provide an environment conducive to poultry performance by utilizing heat recovery ventilation. This would improve profitability and reduce the carbon footprint for broiler farms to improve environmental quality.

The project started in October of 2010 with the purchase of equipment followed by the installation of HRV and monitoring. The first trial ran from January – March of 2011. The second trial began March of 2011 and will end in May of 2011. Evaluation of the data and findings will be submitted for publication after the completion of the second trial.

Key members of this study have been Starkweather, Biofuels Technology Instructor at Crowder College; Aubrey “Bill” Reynolds, Engineering Consultant for Benchmark Group, Rogers, AR; Scott Madden, Sales and Business Development Director of American Aldes Ventilation Corporation, Bradenton, FL; University of Arkansas Poultry Research Farm Program Manager, Tom Tabler, PhD; University of Arkansas Biological and Agricultural Engineering Assistant Professor, Yi Liang, PhD; Scott Carter of Jack T. Carter Company, Rogers, AR; and Richard Ver Muelen of Northwest Arkansas Sheet Metal, Rogers, AR.

New Line of Smart Ventilation Kits

American Aldes presents a brand new line of smart ventilation kits that take whole-house Indoor Air Quality and Central Ventilation to a new level. New VentZone® Zoned IAQ with Heat & Energy Recovery Kits use the most advanced central ventilation technologies available to provide tightly sealed, energy-efficient homes with precise amounts of continuous fresh air that has been pre-heated or cooled by the energy from stale, air exhausted from the bathrooms.

Tightly sealed new homes are a great way for homeowners to save money and energy. Unfortunately, a tightly sealed home traps pollutants and mold, causing moisture inside a home. Stale, contaminated air must be exhausted, and clean, fresh air must be introduced. Until now, the challenge was introducing fresh air directly into a home without putting too great a load on heating and air conditioning systems, which negates much of the energy savings that come from having a tightly sealed home. VentZone® Zoned IAQ Kits overcome this issue by removing the primary source of stale and humid air directly from the bathrooms, and then taking the energy from the stale air and moving it to the fresh air being introduced. The cores inside the Heat or Energy Recovery Ventilator (HRV or ERV) moves heat from the warm, stale air being exhausted to the cool, fresh air being introduced without any cross contamination between the two airflows. During the summer months, the same process works in reverse:  heat is removed from the warm, fresh air being brought into the house and moved to the stale, cool air that is being exhausted.

VentZone® Zoned IAQ Kits provide energy savings and performance benefits as well. Kits are very quiet, a vast improvement over noisy spot bathroom fans. Also, Kits keep the air pressure inside the home balanced because they bring in air proportional to what is exhausted, unlike spot bathroom fans, which can force a home into a negative pressure scenario.

How it Works: The Kits include one Zone Register Terminal (ZRT-2) for each full bathroom and one ZRT-1 for each half bathroom. These ZRTs mount in the ceiling in place of bathroom fans. When the bathrooms are unoccupied, a Constant Airflow Regulator (CAR) inside the ZRT exhausts a low volume of air from the bathroom at all times. When the bathroom is occupied, an electronic timer tells the ZRT to open to high volume exhaust, which causes the HRV or ERV to go to high-speed mode to quickly and effectively remove odors and moisture. The conditioned fresh air introduced into the home can be distributed by the return plenum of a forced air system or by dedicated supply air ducts.

The Constant Airflow Regulator (CAR-II) exhausts a precise amount of air from each bathroom (adjustable to 10, 20 or 30 CFM per bathroom). Because the CAR-II is automatically self-balancing, it ensures that the ventilation system is accurately meeting the energy efficiency and ventilation codes/standards such as: ASHRAE 62.2, TITLE 24, LEED for Homes, ANSI Green Building Standard, ENERGY STAR IAQ, and various state codes. Accurate control of the ventilation airflow is critical for balancing a home for maximum energy efficiency and Indoor Air Quality safety.

Installation is simple and cost effective. The entire system is connected via 24V low voltage wiring and powered directly from the HRV or ERV. The system uses insulated 5” flexible duct for 2-3 bathroom homes and 6” flexible duct for 4-5 bathroom homes. The components are sold as a kit based on the number of bathrooms; just add insulated flexible ductwork and fittings. The entire Kit, which provides whole-house IAQ with heat or energy recovery and zoned central bathroom ventilation, costs less than many standalone HRVs or ERVs.

Hotels and Condos Find Huge Energy Savings

With energy costs soaring, savvy hotel and condo owners are finding highly effective ways to conserve energy and save money. By installing American Aldes Constant Airflow Regulators (CAR-II) in bathroom and kitchen exhaust vents, owners and operators are able to accurately and automatically control the amount of heated or conditioned air that is constantly blown out of their buildings. While having the airflow automatically regulated improves the indoor air quality and enables the use of smaller high-efficiency fans, the greatest savings comes from the reduced load on facilities’ heating and cooling systems. Constant Airflow Regulators are inexpensive (comparable to a manual damper after balancing), require no power to operate, and are easy to install.

Some properties are seeing complete return on investment in less than six months. Having automatic airflow regulation is an easy way to ensure building code ventilation requirements are effectively met, and it improves the Indoor Air Quality in buildings. Marc Zuluaga, P.E., of the Building Systems Consulting Firm Steven Winter Associates (www.swinter.com) in New York said, “We conducted a one-year energy study on a project with the ducts sealed and the Constant Airflow Regulators installed and saw over 25% reduction in heating energy use in a 9-story NJ apartment building.”

Insufficient ventilation can result in excessive moisture, which can cause mold to grow in walls and behind the vinyl wallpaper that is often used in hotels. The Florida Department of Business and Professional Regulation said that complaints regarding mold infestation are the fastest growing complaint by their lodging division.

The other significant benefit to using a self-balancing device is that it can adjust for and correct the detrimental results of “stack effect” in tall building systems. Stack Effect is a common challenge for hotels and condominiums. The difference in temperatures inside a building versus outside causes the ventilation system to go severely out of balance. Too much air is drawn from some floors, while other floors do not receive enough ventilation. Stack effect can also cause cross contamination, meaning stale air is drawn from one floor and forced back into another. Constant Airflow Regulators can correct stack effect by automatically adjusting to the changes in static pressure so that energy is not wasted and optimal Indoor Air Quality is maintained.

Constant Airflow Regulators are being installed worldwide in response to the global demand to reduce building energy consumption. Constant Airflow Regulators come in square and round configurations and can be used to regulate airflow in exhaust, return, or supply systems. American ALDES provides an energy savings estimator program to help determine the potential savings from automatically regulating ventilation systems. Download the energy estimator program in Resources.
