Recommendations from CDC and ASHRAE Epidemic Task Force Regarding Ventilation:
- Increase the percentage of outdoor air, (e.g using economizer modes of HVAC operations) potentially as high as 100%, increasing the total airflow supply to occupied spaces.
- Continue operation of the ERV component appropriate to climate conditions.
- Dilution of contaminants, including infectious aerosols, by outdoor air ventilati,on is an integral IAQ strategy in ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality
Airxchange solution for Maximizing energy performance
Energy Recovery Ventilation (ERV)
Energy recovery ventilators are specifically designed to increase fresh outdoor ventilation air cost-effectively. They do so by efficiently preconditioning fresh air with recycled energy to reduce outdoor air ventilation loads by up to 80%.
At the heart of all ERV systems is an Energy Recovery Component, usually in the form of an Energy Recovery Wheel
At the heart of all ERV systems is an Energy Recovery Component, usually in the form of an Energy Recovery Wheel or Fixed Plate Heat Exchanger. These components are directly responsible for recycling the energy from indoor air and are critical for maintaining peak system operation. Learn to maximize the energy recovery component’s performance if users have one in place or upgrade the HVAC system with ERV technology to ensure optimum indoor quality and improve the efficiency and performance of unit.
Existing Airxchange component
If an existing component is made by Airxchange:
- Clean the Media Segments– Follow the cleaning instructions outlined by Airxchange to clean the segments outside of the cabinet.
- Purchase New Media Segments– If cleaning is not an option, a quick and affordable fix is to upgrade the segments. This takes less than an hour with only hand tools and will bring the wheel back to factory performance levels.
- Follow the Routine and Preventative Maintenance Checklist to check the full Wheel Operation.
Non-Airxchange component
If an existing component is not made by Airxchange:
- Airxchange Energy Recovery Wheels serve as a direct replacement for most wheels in the market often exceeding existing design performance levels.
- Airxchange Replacement wheels come disassembled to eliminate major building and unit alterations and can be assembled inside the existing wheel space or wheel frame.
- The process can be completed in less than a day, and often by the onsite HVAC team.
- Component paybacks are typically less than a year and will show a rapid improvement in indoor air quality and comfort.
- Purchase a replacement Fixed Plate Heat Exchanger to quickly upgrade the existing component. Learn more.
Absence of ERV system
If users do not have an ERV system in place:
- ERV is an easy addition to existing buildings.
- Implementing ERV technology into the existing HVAC system ensures optimum indoor quality, and improves the efficiency and performance of the unit.
