According to Sam West, an engineer at the CSIRO. “A lot of people don’t realise that fridges cycle on and off regularly, which means you’ve got a bit of discretion about when they use power”. The controller enables communication between other fridges on the network and also the power source. It has the potential to smooth out fluctuations in electricity demand by enabling fridges to manage available power. Simulations have shown … Continue Reading
