Coordinator and dispatcher
In addition to the three chain links producer, distributor, and consumer, there are the logical links named
coordinator and dispatcher.
Supply chains for a room
You can define different consumer needs for a room, such as heat, refrigeration and fresh air.
Heat demand
The hot water supply chain exists for heat demand. The medium hot water is prepared in hot water
generation and distributed via a heating circuit. The heat is emitted to the room as needed via a heating
surface. If air is the carrier of heat, this is done via pre-control and air posttreatment.
Refrigeration demand
The cold water supply chain exists for refrigeration demand. The medium cold water is prepared in cold
water generation and distributed via a cooling circuit. The refrigeration is emitted to the room as needed
via a cooling surface. If air is the carrier of refrigeration, this is done via pre-control and air posttreatment.
Fresh air demand
The need for fresh air is met by the air supply chain, where the medium is produced by the air treatment
plant, distributed via the ducting, possibly adjusted to differing requirements of the room by an air
posttreatment plant, and transferred to the room via air outlets.
HVAC application architecture
The HVAC application architecture contains an overall view of typical heating, ventilation and air
conditioning plants with distributed applications and is based very strongly on the supply chains (energy
and substance flows) in building services systems.
● The mutually standardized exchange and re-use of HVAC-relevant demand and coordination signals is
possible in distributed applications.
● The HVAC application architecture structures the HVAC functions into meaningful units, interfaces and
functional mechanisms.
● The HVAC application architecture is scalable and independent of product and communication
standards.
HVAC system view
The consideration and definition of the HVAC application architecture and its functionality gives rise to the
HVAC system view, which comprises:
● Plant (primarily HVAC plants)
● Operator interventions
● Functional units
