Outline
The function that detects existence of humans in the air-conditioned room and reduces the
capacity when no humans are available in the room in order to save electricity by means of a
human motion sensor.
Processing
1. Detection method by human motion sensor
"
This sensor detects human motion by receiving infrared rays and displays the pulse wave
output.
"
A micro computer in an indoor unit carries out a sampling every 20 msec. and if it detects 10
cycles of the wave in one second in total (corresponding to 20msec.× 10 = 100msec.), it
judges human is in the room as the motion signal is ON.
2. The motions (for example: in cooling)
"
When a micro computer doesn’t have a signal from the sensor in 20 minutes, it judges that
no body is in the room and turns off the human detection LED, operating the unit in
temperature sifted 2°C from the set temperature. (Cooling : 2°C higher, Dry: 1°C higher and
Auto : according to the operation mode at that time.)
★
1 In case of Fan mode, the fan speed reduces by 50 rpm.
If the sensor detects the outputs 10 times/sec.
or more, it judges humans are available.
