Why can they be large variations in AML device delivered savings?
Energy savings can vary significantly, depending on the sizing of the air-conditioner, the maintenance history and condition of the air-conditioning unit (whether cooling fins and filters have been cleaned and refrigerant levels topped up) and a range of environmental factors. These factors include whether the compressor is installed in the shade or in direct sunlight and of course the loading on the air-conditioning unit. Delivered energy savings will be greater during the cooler months and lower in the full heat of summer when the air-conditioning unit is at or near its design limit. As the condition of the air-conditioner is important (servicing can itself reduce energy requirements), the AML device has built-in alarms that warn when the air-conditioning unit requires servicing.
