11. 5) Comfort - Characteristic of room temp. change
Continuous Operation
Advanced inverter technology ensures desired temperature is reached quickly and efficiently.

12. 5) Comfort - DC Hybrid inverter
PAM inverter
- assists the compressor at
maximum load operation.
PWM inverter
the partial load operation.
At the heart of the air conditioner is the eco-conscious hybrid inverter (featuring PAM* and PWM*) developed by Carrier.
It achieves industry-leading energy saving and powerful cooling.  
The hybrid inverter is an epoch making high power, energy saving technology that achieves a high power factor and high efficiency simultaneouly.
"Hybrid" refers to the integration of two circuits, that is, the double effect of PAM for the high power factor and PWM for high efficiency realizes high power and energy saving at a single stroke.
The hybrid inverter makes the most of every drop of electricity and delivers a high power factor as high as 95% (meaning little energy is wasted !) PAM inverter assists the compressor at maximum load operation while PWM inverter assists the compressor at the partial load operation.
