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
