Inverter Advantages Compared to Non-Inverter
Inverters are devices that are able to vary their operating capacity by adjusting frequency. Inverter air
conditioners can vary their cooling capacity by adjusting the power supply frequency of their compressors.
In contrast, non-inverter air conditioners have a fixed cooling capacity and can only control the indoor
temperature by starting or stopping their compressors.

What is COP?
An air conditioner’s COP (Coefficient of Performance)
indicates how efficiently the unit uses energy. A higher
COP means greater energy efficiency. It also means
lower electricity consumption, so you save money.

Inverter air conditioners are able to vary their operating capacity. Non-inverter air conditioners can
only operate at a fixed capacity.

Energy Saving
After the indoor temperature
approaches the set temperature,
Inverter Control adjusts to low
capacity operation to maintain this
temperature. This makes inverter
models more energy-saving than
non-inverter models, which must
repeatedly start or stop their
compressors to maintain the room
temperature.
Comfortable
Inverter air conditioners finely adjust
capacity according to changes in the
air-conditioning load and the difference
between the indoor temperature and
set temperature is small. These give
higher comfort levels than with non-
inverter air conditioners.
Powerful
Inverter air conditioners operate at
maximum capacity as soon as they
start up. As a result, the set
temperature can be reached more
quickly.
Compliance to Mandatory Energy Label
The 5 models listed below have received Singapore’s
National Environment Agency (NEA) energy labels for
household electrical appliances.
