Start from a familiar cold-storage problem and watch HVACR Studio move from observation to engineering action.
Continue →REFCOLD 2026 · LIVE PRODUCT WALKTHROUGH
Choose the refrigeration job. Follow the real workflow.
HVACR Studio should be easy to demonstrate even to someone seeing it for the first time. Pick the role that matches the visitor, show immediate engineering value, then go deeper only when Project traceability, commissioning, maintenance or reporting matters.
Prepare this browser once while online before the stall opens. The cache is deliberately limited to approved REFCOLD demo/free routes and static assets.
REFCOLD VISITOR JOURNEY
Try Issue Finder Free →Experience value first. Register only when you choose to keep the work.
HVACR Studio does not use registration as the first demo screen. The natural path is Demo → Try Free → Save → Register → Professional.
Use the Free Issue Finder on your own field symptom. No Project and no registration are required to get value.
Continue →Only when you choose Save to Project does HVACR Studio ask you to continue into a signed-in Professional workflow.
Continue →REFCOLD access follows the existing managed-link and approval policy. The journey marker never grants access by itself.
View REFCOLD access →Project/equipment context, corrective actions, Before/Retest evidence, human verification, RCA/CAPA and controlled reports stay connected.
Continue →Access boundary: the REFCOLD journey marker is only navigation context. Campaign attribution, eligibility, approval and Professional entitlement remain governed by the existing managed REFCOLD link and access authorities.
TRY SOMETHING IN 60 SECONDS
Immediate value before login.
These three routes are the fastest REFCOLD demonstration starters. They do not require a Project merely to see the engineering workflow.
Review a logger CSV locally, inspect excursions, sampling gaps and observed recovery without uploading the raw file.
Open now →Use blend-aware SH/SC and optional system-performance relationships with explicit pressure reference and sourced targets.
Open now →Start from real field symptoms—temperature, recovery, defrost, frost, airflow, cycling, low suction or suspected leakage—before deciding whether Project history is needed.
Open now →ROLE-BASED DEMO TRACKS
Four stories for four kinds of REFCOLD visitor.
Use one track at the stall instead of clicking through unrelated modules. Each track shows free value, the Professional handoff, evidence produced and the engineering boundary.
Service technician / refrigeration engineerFREE + PROFESSIONAL
Room not reaching temperature
Move from a temperature concern to measured refrigeration context, corrective work and retest without jumping straight to refrigerant charge.
- 1 · OBSERVEReview the temperature event
Open logger CSV locally, identify excursions/gaps and separate room-air/product-core context.
Try this step → - 2 · CHECKCheck refrigeration system performance
Use blend-aware SH/SC plus optional pressure ratio, evaporator/condenser air and discharge-temperature context.
Try this step → - 3 · DIAGNOSEStart from the actual symptom
Use Issue Finder for guided checks instead of converting one abnormal reading into a root cause.
Try this step → - 4 · RECORDMove the job into Project context
Choose the cold-room Project to preserve equipment, evidence, Actions and retest history.
Open workflow → - 5 · VERIFYRetest and report
Save representative evidence, verify the corrective result and issue the applicable cold-room/refrigeration service report.
Open workflow →
✓ Logger review stays local until the user explicitly saves a summary.✓ SH/SC uses dew/bubble branches and explicit pressure reference.✓ Corrective work remains separate from verified retest evidence.
Boundary: One snapshot does not prove charge condition, leakage, restriction, compressor health or product disposition.
Commissioning engineer / contractorPROFESSIONAL
Commission a cold room systematically
Start one traceable field session, inspect the right cold-storage systems, then continue into versioned equipment commissioning packs and evidence.
- 1 · VISITStart a Cold Storage Site Visit
Group the field session and use the guided room/door, evaporator/defrost, condensing-unit, controls, loading and safety prompts.
Open workflow → - 2 · PRE-COMMISSIONUse the correct equipment pack
Create a versioned Cold Room, Condensing Unit or Evaporator pre-commissioning checklist.
Open workflow → - 3 · FUNCTIONALRun functional checks against the approved basis
Record actual outcomes and link measurements to Engineering Evidence rather than generic limits.
Open workflow → - 4 · FOLLOW UPPromote unresolved work
Route observations into Project Actions or Issue Finder when formal follow-up is needed.
Open workflow → - 5 · ISSUEPreserve the record
Use existing Site Visit / Commissioning report paths so later reviewers can see what was checked and what remains open.
Open workflow →
✓ Six versioned cold-storage commissioning packs are available.✓ Quantitative checks point to sourced Project/OEM/client criteria.✓ Completing a visit/checklist does not silently close Issues or Actions.
Boundary: Commissioning packs organize evidence and engineer-entered outcomes; they do not create product release, certification or universal acceptance limits.
Facility / O&M teamPROFESSIONAL
Turn recurring cold-room maintenance into visible history
Use the same equipment identity for maintenance planning, service history, recurring attention, Issue diagnosis and verification.
- 1 · PLANChoose a bounded maintenance task
Use Cold Room, Condensing Unit or Evaporator task templates to prefill scope only.
Open workflow → - 2 · SCHEDULEEnter the real maintenance interval
Set recurrence and due date from the actual OEM, statutory or approved facility requirement.
Open workflow → - 3 · RECORDDocument work performed
Keep inspection, cleaning, service or replacement history against the same Project equipment.
Open workflow → - 4 · INVESTIGATEEscalate repeated or abnormal conditions
Use Issue Finder and Connected Equipment Health where applicable instead of treating recurrence as automatic diagnosis.
Open workflow → - 5 · VERIFYClose only after evidence
Use Project Actions and retest/verification evidence when corrective work needs formal closure.
Open workflow →
✓ Maintenance templates never prescribe recurrence or due date.✓ Repeated conditions remain rule-based attention signals, not AI diagnosis.✓ Connected findings stay read-only until a user deliberately starts follow-up.
Boundary: HVACR Studio organizes maintenance evidence; OEM/site safety procedures and qualified electrical/refrigerant work remain authoritative.
Consultant / reviewer / ownerPROFESSIONAL
Review what happened without reconstructing the job
Move from saved measurements to sourced criteria, open actions and immutable issued records while keeping scope and provenance visible.
- 1 · SOURCEReview the saved value and criterion
Compare a selected Project value with the exact sourced criterion/design target instead of a hidden generic rule.
Open workflow → - 2 · CONTEXTInspect the supporting field trail
Review Site Visits, logger/refrigeration evidence, commissioning outcomes and instrument context.
Open workflow → - 3 · FOLLOW UPSee unresolved Issues and Actions
Keep observations, diagnosis, corrective work and verification status distinct.
Open workflow → - 4 · REPORTOpen controlled reports
Review immutable revisions rather than relying on an editable live page as the final record.
Open workflow →
✓ Project evidence retains source/context instead of only a bare number.✓ Issued reports preserve frozen revisions and evidence links.✓ Review status does not overwrite the original field record.
Boundary: Review workflows support engineering judgement; they do not replace contractual authority, statutory acceptance or client-specific release decisions.
WHAT TO PROVE IN THE DEMO
Show the product logic, not just screens.
Free-first: logger review, refrigeration diagnostics and Basic Issue Finder can demonstrate value before Project setup.
Project continuity: equipment, evidence, Issues, Actions, commissioning, maintenance and reports stay connected once traceability is needed.
Cold-storage specific: dedicated Site Visit guidance, six commissioning packs, 15 maintenance task templates and curated NCCD/FAO/WHO source cards are available with applicability boundaries before Project adoption.
Engineering boundaries stay visible: no universal commodity limits, automatic charge diagnosis, product release or invented maintenance interval.
THE REFCOLD STORY
Observe → Check → Diagnose → Act → Retest → Report
The strongest demo is not “we have many tools.” It is that HVACR Studio keeps the engineer in one understandable workflow as the job becomes more serious.
