The ERU™ (Energy Recovery Unit) is an innovative and technologically advanced design specifically created for applications that require high outside air capacity. The engineer, owner and contractor were all looking to create a design that provided the maximum energy savings while meeting the Mass. Flat plate exchangers consist of alternating layers of plates that are separated and sealed with a heat or energy recovery core treating incoming air. Project Challenge:     This was a new building project. Let’s assume you have a 4 Ton Unit ( Click Here to understand and interpret HVAC Tonnage ), and are required by code to introduce 25% fresh outside air (in this case … Energy Recovery Ventilators Improve Indoor Air Quality and Reduce Energy Costs With ERVs. During warmer seasons, the system pre-cools and dehumidifies the incoming ventilation air by sending the rejected heat into the exhaust airstream to cool the condenser coil at a lower temperature. rotary heat exchanger—also called an energy wheel, or energy recovery wheel—and the benefits of incorporat-ing such a device in an air handling unit. Both sensible and latent (moisture) heat is transferred. Several one-hour classes on different topics will be presented each week through August. A pump circulates water between the two. Web Design by flyte. bypassing the energy-recovery device, to avoid cross-leakage, may be desirable.2,3 But this depends on the type of ventilation system being used. energy recovery unit – eru™ Wet bulb energy recovery: increase efficiency by more than 50% over a standard dry bulb exchanger. The major advantage of this system was that it incorporated the use of a heat pipe to recover 65% of the energy from the exhaust air stream. 1 / 8 Image not found: Images/M3/Fan_Array_1.jpg The Power of Ions – NPBI Technology Delivers Cleaner Indoor Air, ASHRAE Guidelines for Reopening Schools and Universities, Biocomposite is the Future of the HVAC Industry, Reduce Outdoor Air with Needlepoint Bipolar Ionization, Custom Air Handling Unit Design Critical Decisions, Amherst College Science Center | Pumped Glycol Energy Recovery System, New Look DOAS Units – less space, less noise, less cost. High-performance, Efficient Energy Recovery Systems to Reduce Energy Costs. Learn how to apply our technology to your industry. With over 35 years of experience manufacturing energy recovery ventilation products and components, and an installed base of over 285,000 units, Airxchange has solidified itself as the leader in Energy Recovery Wheel technology. We did a preliminary estimates and determined that the energy recovery effectiveness would be about 45% for this system. We are focused exclusively on designing and manufacturing high-quality, energy-efficient air handling systems. Let me better explain. AIR HANDLING UNITS : Energy Labs custom Air Handling systems are the premium solutions for controlling building environments. As the wheel rotates, it draws in heat energy and releases it into the colder airstream. That is a huge plus. The resulting system is at least 50% more energy efficient. These systems help capture the energy in the airstream that would otherwise be exhausted to the atmosphere and use it to either pre-heat or pre-cool the outdoor airstream, depending on the season. are the most cost-effective, 100% outdoor air energy recovery systems of their size available. Energy recovery systems recycle the heating and cooling energy present in your air handling system to reduce costs. Energy recovery systems supply a steady stream of conditioned fresh air to your building environment, reducing the amount of particulates in your air, thereby improving indoor air quality. Maintaining indoor air quality is vital to the health and well-being of a building’s occupants. An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Most energy recovery devices transfer heat (sensible) energy only. The original design included a pumped glycol energy recovery loop connecting each AHU to respective ERUs.

Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air.
