This is a double-elliptical floor-mounted air conditioner with a geometrical aesthetic inspired by modern architecture. The front column is a purification module and the rear column is an air supply module for independent or combined use. When combined, the purification module can assist the air supply module to enhance air volume to further distance. With the fusion of natural wind and the airflow between the two columns, the device can adjust the air temperature comfortably. The discomfort caused by direct-blow is thus removed.
