Heat recovery system
With the new equipment MVD 3 pipes, we can heat and cool simultaneously different areas with a single HVAC system. It saves up to 50% in energy costs compared to a conventional 2 pipes system.
Wide range of capabilities
Thanks to the 5 basic modules (8, 10, 12, 14 and 16HP), system capacity can range from 8HP to 64HP in 2HP increments. In total you can connect 64 indoor units or a total indoor capacity of 130% from the outdoor unit capacity.
Compressors and DC Inverter fan motors
All range of equipment add compressors and DC Inverter fan motors, in this way, the performance for middle-frequency system is improved and a more sensitive and effective control is assured.
Adjustable Outdoor Heat Exchanger
Two parts condenser individual design, the unit can distribute a part of evaporator to be as condensing area according to the heating load requirement to improve the utilization rate of the condenser.
Auto Mode Control
Under the Auto Mode, the indoor unit can change the operation mode automatically, to keep the indoor temperature at a constant level.
Automatic adjustment of the capacity
The heat exchanger is split into two parts, thus both parts can be used at the same time: one part to evaporate and the other to condense, or you can use only one part if working with a partial load.
Compatible with all MVD indoor units
Wide operating range
The VR4+ system can operate in extreme temperatures conditions in heating mode up to an outdoor temperature of -20 °C, in cooling mode up to 48 °C and in both modes simultaneously from -5 °C to 24 °C.
Heat Recovery, EER up to 7.0
Heat recovery is achieved by diverting exhaust heat from indoor units in cooling mode to areas requiring heating, maximizing energy efficiency, reducing electricity costs and leading to high part-load efficiencies (up to 7.0 in the 8HP category).
Continuous Heating During Defrost Operation
Each heat exchanger is defrosted by using heat transferred from one heat exchanger to the other in the outdoor unit. Defrost has no impact on the indoor unit in heating mode.
