During the operation of an air conditioner the air conditioning unit expels moving air. This moving air dissipates into the ambient air surrounding the air conditioner and any potential energy associated with the moving air is lost. The dissipation of the moving air is a lost opportunity to recover energy and improve energy conservation efforts.
Every time the AC unit turns on - the ACERU creates energy out of the wasted wind energy from the AC unit.
The ACERU is scalable to any size air conditioner and can be up-sized to be adapted to commercial and industrial applications (ie: Cooling tower fans or exhaust fans) and can be installed in any position. It requires no modifications to the AC/HVAC units and creates energy out of the air blowing out of the AC units.
The ACERU can be constructed out of almost any material - the pyramid shape is self-supporting (the initial R&D models were built with cardboard) even with the weight of the fans installed. The internal inverted pyramid also provides support and directs air flow through the fans.
In 2020 the US average home cost to operate a central home air conditioner was approx. $1686 per year (12 hours a day/3500 watts/$0.11 per/kWh) which can be up to 70% of the home's electricity bill. In warmer states homes can have up to 4 (or more) central AC units on them - this would equal a yearly cost of $6744/year or $562/month.
Depending on the efficiency of the AC unit (energy recovered varies) - power is recovered and can be used to charge a bank of batteries (similar to a wind turbine) and/or run through an inverter to either power electrical appliances in the home or sent directly back to the electrical grid to lower home energy costs.
Every time an AC unit runs the ACERU can recapture some of the energy costs by utilizing the wasted wind energy expelled by the cooling fan.
Studies show that keeping your air conditioner out of direct sunlight helps it perform more efficiently. The ACERU covers the top (or side) of the air conditioning unit and keeps the direct sunlight off of it. It performs a twofold function, keeping the direct sunlight off without increasing any power consumption and generates power from the exhausted air through its fan array.
