Energy efficient solution

2-1 Low running costs - VRVII & VRV-WII
• VRV systems have low running costs because it permits each zone to be controlled individually. That is, only those rooms that require air conditioning
will be heated or cooled, while the system can be shut down completely in rooms where no air conditioning is required.
• VRV units have the highest COP/EER in the market in the most common operating area
2-2 Most advanced reluctance brushless DC compressor technology - VRVII & VRV-WII
The scroll compressor is driven by the newly developed motor, enabling better performance, higher enery efficiency resulting in higher energy cost
savings.

2-3 HRV - Heat Reclaim Ventilation System - VRVII & VRV-WII
• Heat and humidity are exchanged between supply and exhaust air, which
-brings outdoor air close to indoor air conditions
- recovers energy loss
- realises considerable reduction of air conditioning capacity
• The heat exchanger modulates the humidity and temperature of incoming fresh air to match indoor conditions.
• The balance achieved between indoor and outdoor ambients, enables the cooling/heating load placed on the air conditioning system to be reduced.
(heat and humidity are exchanged)
• Most energy saving solution as smaller indoor units can be selected:
-size down of indoor units down to 40 %
-payback total VAM system: ±2.5 years*
*conditions: outside cooling conditions: 30°C / outside heating conditions: - 8°C
inside cooling conditions: 24°C / inside heating conditions: 22°C
ventilation per room: 150m3/h
• Ideal modular concept to cope with the fresh air requirements
2-4 Auto restart capability - VRVII & VRV-WII
Even after exceptionally long power failures, the built-in auto restart capability ensures automatic system start up. Since the preset memory is not erased
by interruptions in power supply, no programme resetting is necessary.
