Indoor unit with outdoor air treatment
Using outdoor air, the temperature can
be brought near room temperature with
minimal cooling capacity through the
use of outdoor air.
Four air conditioner functions can be managed using a single remote control. This makes it easy to obtain
high-quality and energy-efficient outdoor air treatment.
During group control operation, the unit has a capacity
equivalent to two standard indoor units. Up to 16 standard

remote control
Control of the HRV (VKM) type indoor unit is managed using
the remote control of the standard indoor units connected.
Individual outdoor air treatment operation is
possible by connecting an optional remote
controller.
Reduced pressure loss and quieter operation internally lowers the noise output of the 1,000m
system to 38dB (VKM100GAMV1 at 50Hz 240V, High mode).
Rather than using separate ventilation, air conditioning, and humidifying components, the system
incorporating HRV (VKM) integrates all functions, reducing the total number of indoor units and facilitating
a far simpler system. The installation space becomes smaller and the labor required for installation and
