AIRLUX DC Inverter Heat Pumps / Air Conditioners provide cooling and heating with considerable energy savings. Equipped with variable speed DC Inverter compressors AIRLUX units offer compact, quiet, stylish wall-mounted design which perfectly blends into any environment. These units have optimized air duct design for a range of noise reduction measures resulting in ultra-low noise performance. 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. Power: Inverter air conditioners operate at maximum capacity as soon as they start up. As a result, the set temperature can be reached more quickly. Comfort: 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. Low outside operating temperature -15C.
