AC units are manufactured to function on a pre-established power scale. Therefore, we are obliged to select units which cover the power requirement of the designated zone. In that scenario, lack of precise selection leads to higher costs in investment with the multi-split installations. On the other hand, ducted units can be designed with more accurate selection and that way, oversizing the AC and electrical installations can be avoided. In addition, compared to the ducted solutions without zoning, Airzone offers the benefits of calculation for the entire system. As our solution functions according to the user preference which allows simultaneous control of the AC unit, the required power capacity is less than what the traditional systems consume which operate on maximum power threshold.
