MasterFormat Division 23 72 00: Air-to-Air Energy Recovery Equipment

In the realm of modern HVAC systems, energy efficiency reigns supreme. Building owners and managers are constantly seeking ways to reduce operating costs without compromising occupant comfort. This is where MasterFormat Division 23 72 00 - Air-to-Air Energy Recovery Equipment comes into play. This division encompasses specialized equipment designed to reclaim waste energy from exhaust air and transfer it to incoming fresh air, thereby enhancing energy efficiency and reducing HVAC system loads.

What is Air-to-Air Energy Recovery Equipment?

Air-to-Air Energy Recovery Equipment, often referred to as ERVs or HRVs (Heat Recovery Ventilators), are mechanical ventilation systems that facilitate the transfer of heat and/or humidity between two airstreams – typically exhaust air and incoming fresh air. These systems utilize a heat exchanger core to transfer energy without directly mixing the airstreams, ensuring a continuous supply of fresh, preconditioned air while minimizing energy losses.

How Does Air-to-Air Energy Recovery Equipment Work?

ERVs and HRVs operate on the fundamental principles of heat transfer. As exhaust air passes through one side of the heat exchanger core, it transfers a portion of its heat and/or humidity to the incoming fresh air stream passing through the other side. This energy exchange preconditions the fresh air, reducing the load on the HVAC system to heat or cool it to the desired temperature and humidity levels.


There are two primary types of air-to-air energy recovery systems:

  • Enthalpy Wheels: These systems utilize a rotating wheel impregnated with a desiccant material to transfer both sensible heat (temperature difference) and latent heat (moisture content).
  • Fixed-Plate Exchangers: These systems employ stationary plates with alternating airstream passages to transfer sensible heat. Some fixed-plate exchangers incorporate a specialized membrane to transfer moisture as well.

Where is Air-to-Air Energy Recovery Equipment Commonly Used?

Air-to-Air Energy Recovery Equipment is particularly well-suited for applications where:

  • Ventilation rates are high: Such as in commercial buildings, schools, and hospitals.
  • Climate conditions are extreme: ERVs and HRVs excel in hot, humid climates where they can pre-cool and dehumidify incoming fresh air or in cold climates where they can pre-heat and humidify incoming air.
  • Indoor air quality is a concern: ERVs and HRVs provide continuous ventilation, diluting indoor air contaminants and improving overall air quality.

What are Installation Best Practices for Air-to-Air Energy Recovery Equipment?

Proper installation is crucial for optimal ERV/HRV system performance and longevity. Key best practices include:

  • Sizing the unit correctly: Factors such as building volume, occupancy, and ventilation requirements must be considered.
  • Ensuring proper ductwork design and installation: Ductwork should be sized appropriately to minimize pressure drops and ensure proper airflow.
  • Installing condensate drainage: Condensate can form during the dehumidification process and requires proper drainage.
  • Implementing a comprehensive control system: Controls should monitor and adjust airflow rates, temperature, and humidity levels for optimal performance.

What are the Top Manufacturers for Air-to-Air Energy Recovery Equipment?

The market for Air-to-Air Energy Recovery Equipment is competitive, with several reputable manufacturers offering a wide range of products. Some of the top manufacturers include:

  • Carrier
  • Trane
  • Daikin
  • Lennox
  • Mitsubishi Electric

Conclusion

Air-to-Air Energy Recovery Equipment plays a pivotal role in achieving energy-efficient and sustainable building designs. By recovering waste energy and preconditioning incoming fresh air, ERVs and HRVs reduce HVAC system loads, lower energy consumption, and improve indoor air quality. As building codes continue to emphasize energy efficiency, the adoption of Air-to-Air Energy Recovery Equipment is expected to grow, contributing to a more sustainable future.
