Review Process

The review process for AS/NZS 4234 modelling & submission projects occurs at two distinct stages of the modelling project:

• Gate A Review occurs at the end of the Modelling phase, prior to application preparation
• Gate B Review occurs at the end of the Application Preparation phase, prior to submission

General Rules

• If any checks fail, stop reviewing immediately and return back to Project Lead (PL).
  • Exception for minor/aesthetic issues which do not flow through into the 4234 modelling, i.e. 5125 report formatting issue.
• A 100% pass rate is required to proceed to the next phase phase.
• For “FAIL REASON” clearly state what is the issue. Be specific, i.e:
  • “Missing 5125 report from Client Material”
  • “FP value is not consistent between 4234 report and .dck files.”
  • “Tank model ID not consistent with 4692 report”
  • “Tank drawing - volume above HP sensor is not >45% of tank volume.”

Gate A Review

1. Documentation
   1. Check that all documentation for modelling is present in 02-Client_Material: AS/NZS 5125.1 report + 1-minute data, AS/NZS 4692.1 report, tank & condenser drawings.
2. Model IDs
   1. Check system, tank and HP model IDs reconcile between test reports and tank drawings.
3. Tank drawings
   1. Check all tank volumes and dimensions reconcile between tank drawing and 4234 Appendix TDS, and tank drawing meets EAE requirements.
4. AS/NZS 4692 report
   1. Check all 4692 data reconciles between 4692 report and 4234 Appendix TDS:
      1. Tank heat loss value
      2. Test report number, date
5. AS/NZS 5125 report
   1. Check all 5125 reporting requirements are met
   2. Test point periods comply with 5125
   3. All TCs reach 60+degC
   4. R^2>0.95, scatterplots provided.
6. AS/NZS 5125 data
   1. Check 5125 data (COP + Power coefficients, Tifr, Low temperature data, Standby power) in the 5125 report matches the modelling
7. AS/NZS 4234 report
   1. Check the 4234 report for formatting and content
   2. Check consistency of FP value
   3. Check data against source material
   4. Ensure clarity of the report explaining any non-standard features
8. TRNSYS modelling
   1. Ensure all modelling meets minimum criteria (MDT≥ 45, Energy Savings ≥ 60%)
   2. Check flow rate modelling for stand-alone systems
   3. Check legionella control compliance
   4. Check FP value consistency to 4234 report

Gate B Review

This review takes place once the application files are prepared for all submissions - CER, VEU, ESS.

1. Documentation
   1. Ensure all audit files are included in 05-Submission:
      1. Residential audit files
      2. Commercial audit files
2. Model IDs
   1. System, tank and HP model IDs reconcile across all documents: certificates, manual, tank drawing, 4234, 5125, 4692, data plate.
3. Tank drawing
   1. All tank volumes and dimensions reconcile between tank drawing and 4234 Appendix TDS, and tank drawing meets EAE requirements.
4. Manual
   1. Brand & model name consistent
   2. Control logic default mode matches modelling settings
   3. Plumbing schematic included
   4. Warranty included (5+ years, company details and instructions provided how to claim warranty)
5. Data plate
   1. System ID matches 2712
   2. Image resolution is adequate
6. Declarations
   1. Control declaration matches modelling + manual
   2. Manufacturer declaration exists if brand/model differs between test report + submission
   3. Authorisation letter included if applicant does not own the test reports used in submission
7. Product upload form (PUF)
   1. Check PUF data is consistent with source material
   2. Spot check the TRNSYS .out files
