100-Apartment Residential Building
Central heating, cooling and domestic hot water
Plant overview
- Air-to-water heat pumps HP1/HP2
- Thermal buffer / hydraulic separation
- Primary and secondary pump sets
- DHW storage, recovery and recirculation
- Heat/energy metering and BMS
DFV connects each design requirement to identifiable assets, sensors, tests, documentation and operational evidence.
How it works
The system architecture is presented as connected engineering functions rather than isolated equipment. Plant, distribution, controls and end-use conditions are linked through a structured DFV evidence chain.
Lifecycle purpose
Commissioning evidence establishes the initial verified state. Operational data and governed change management support later re-verification.
Engineering sizing basis
Concept heating duty ≈650 kWth, arranged as two ≈325 kWth heat pumps. Final selection must be derived from diversified load, design conditions, water temperatures, DHW recovery, part-load operation and resilience.
All figures shown in the demonstrations are concept/reference duties unless explicitly identified otherwise.
Reference basis
Applicable editions, project specifications, authority requirements and specialised standards must always be confirmed for a real project.
What DFV verifies
- Measured thermal output
- Flow/return temperatures and ΔT
- Heat-pump staging and run state
- DHW storage/return temperatures
- Meter reconciliation and commissioning evidence
