Introducing AB-QM 4.0
Engineering the best PICV valve for HVAC 4.0 in smart buildings.
AB-QM 4.0 hydronic enabler for smart buildings
With the AB-QM 4.0 Pressure Independent balancing and Control Valves (PICV), the product range of pressure independent valves for HVAC heating and cooling systems has been extended. The valves are designed for use in combination with conventional, modulating or on/off, actuators. Or for the Danfoss NovoCon® S digital actuator, which can be integrated into Building Management Systems (BMS) via BACnet or Modbus bus-communication. This innovative combination enables HVAC 4.0 solutions in smart commercial buildings concepts such as hotels or offices.
Why PICVs are the best choice control valves in HVAC systems
A buildings’ HVAC system is designed according geographical determined 'worst case' climate conditions. In practice these most demanding conditions seldom occur. As result, the HVAC system operates in partial load conditions most of the time. Achieving hydronic balance while the flow in the system constantly fluctuates requires a dynamic balancing solution. PICVs not only dynamically balance the system. Once equipped with an actuator they also control the flow, allowing more or less water through terminal units to provide rooms with correspondingly more or less heating or cooling.
The main benefit of PICVs:
- 2 functions combined in 1 product
- Accurate pressure independent control performance and 100% valve authority
- Easier to design and commission
- Increased HVAC energy-efficiency
Besides these main benefits there are also complementary benefits:
- Longer lifetime of the actuators, reducing the operational costs
- Increased comfort and less complaints
- Increased efficiency of boilers and/or chillers
We created PICVs now we redefine the value
Danfoss AB-QM 4.0 is the enabler for HVAC 4.0 in smart buildings. It is a completely new designed Pressure Independent Control Valve (PICV) for terminal units such as fan coil units, chilled beams, and climate panels. It still features the unique AB-QM 100% valve authority for best-in-class control performance. But we have redefined the value in four different areas:

New: Digital Design Center – one entry point for all design needsFriday, April 17, 2020Design engineers, specifiers and consultants are under a constant pressure when looking or the best solutions for their designs and customers. To simplify their work and save time, we have developed a new online platform – Digital Design Center.
HotelsThe hotel industry is a highly competitive sector where margins are constantly under pressure. The service towards guests must remain on a high level to hold the hotels' reputation. Saving energy is a key-differentiator. Danfoss offers comfort increasing HVAC solutions which help reduce the energy consumption.
OfficesThe ways office buildings are used is changing fast. Trends such as smart offices, digitalization and flexible work stations require adaptations in the technical aspects as well. Optimal indoor comfort for workers is essential. Danfoss offers comfort-increasing and energy-saving HVAC solutions.
