In independent research at a shopping centre at Narellan, a newly installed Hercules was compared with an existing two stage fixed speed AC technology. Over the 14-day testing period, Hercules achieved total energy consumption savings of 40% compared to the two stage fixed speed air conditioner. On a daily basis, energy consumption savings of between 21% and 69% were achieved.

Based on historical weather observations, the total electrical energy savings expected from the Hercules unit across the four month summer period is estimated to be 46%. This equates to an estimated financial saving of $6,297 (based on $0.18 per kWh) for the same period.

Hercules provided more comfort too. During the trial the hottest temperature day was 38.2°C. The conditioned area for the two stage fixed speed technology reached 26.7°C, while Hercules achieved a temperature of 24.9°C.

On that same day, and despite achieving a cooler temperature, Hercules consumed 62% less electrical energy than the two stage fixed unit.
