ACERU: Air Conditioner Energy Recovery Unit
Air conditioners and HVAC systems continuously expel moving air during operation. Once released, this airflow dissipates into the ambient environment and its kinetic energy is lost. The ACERU recovers this otherwise-wasted energy and converts it into electricity every time the unit runs.
ACERU Design
The ACERU is fully scalable across residential, commercial, and industrial AC/HVAC systems, including applications such as cooling towers and exhaust fans. It can be installed in any orientation and requires no modifications to existing equipment. The unit can be constructed from a wide variety of materials. Its self-supporting design maintains structural integrity with the fans installed, while the internal configuration efficiently directs exhaust airflow through the fan array.
ACERU Cost Recovery
The average annual electricity cost to run a residential central AC or HVAC system in the U.S. typically ranges from $500 to $1,500+, depending on climate, rates, and usage. Commercial and industrial systems—such as those serving office buildings, warehouses, data centers, or cooling towers—can cost many times more, often running into the tens of thousands of dollars per year.The ACERU recovers otherwise-wasted exhaust energy and converts it into electricity that can charge batteries or feed back to the grid, helping offset these significant operating costs. With the addition of a bank of batteries, the ACERU can also be utilized for energy storage across residential, commercial, and industrial applications.
ACERU Efficiency Enhancer
Studies show that keeping an air conditioner or HVAC unit out of direct sunlight improves its efficiency. The ACERU covers the top or side of the unit, providing shade without adding any power consumption of its own. At the same time, it generates electricity from the unit’s exhaust airflow—delivering a dual benefit of improved efficiency and energy recovery.
