Open product step →REFCOLD 2026 · GUIDED WORKING POC
One cold-room problem. One complete engineering story.
Run a clearly labelled synthetic cold-storage case through the real HVACR Studio workflow. The POC starts with a freezer room that is not reaching setpoint, then moves through measured context, guided diagnosis, corrective action, retest, documentation and Project continuity.
Demo-data boundary: the values below are synthetic exhibition data, not a customer Project or engineering acceptance record. The troubleshooting engine and public routes are the real product.
THE HVACR STUDIO USP
CALCULATE → CONNECT → DIAGNOSE → EXECUTE → DOCUMENT → LEARN
At the stall, follow this sequence instead of opening unrelated calculators. Free value comes first; Project context is introduced only when the visitor wants persistent equipment history and controlled reporting.

CONNECT
Keep the room, equipment and evidence togetherThe free POC works without login. Move into a Cold Room Project only when equipment identity, history and traceability are needed.

Use the problem to explain the product.
State the complaint.
“Freezer Room 01 is set to -18 °C but is around -12 °C. What should the engineer check first?”
Show measured context.
Use logger/pull-down review and refrigeration diagnostics to establish evidence before diagnosis.
Launch the real Issue Finder.
The POC opens Cold Room → room not reaching temperature with the synthetic observation and readings already entered.
Answer the guided checks.
For the hero demonstration, confirm the observed airflow/frost clue, then continue through infiltration, refrigeration evidence, load and sensor/setpoint checks.
Record action and retest.
Demonstrate that suggested causes are not treated as completed work. Enter only the action actually performed and then record the new condition.
Share or continue into Project mode.
Show the free share card, then explain how Professional keeps the same job connected to equipment, evidence, Actions, retest and controlled reports.
THREE REFCOLD POC SCENARIOS
One hero journey, two fast alternatives.
Use the first scenario for the full booth story. The other two let a refrigeration visitor immediately choose a familiar problem without changing the product architecture.
Freezer Room 01 not reaching setpoint
Room setpoint is -18 °C, but the observed room condition is about -12 °C and pull-down is slow.
Cold Roomcold room high temp
Presenter cue: Use the guided checks to test airflow/icing, infiltration, refrigeration-side evidence, load and sensor/setpoint context instead of jumping straight to refrigerant charge.
Evaporator repeatedly icing
Frost returns quickly after defrost and airflow across the evaporator is becoming uneven.
Cold Roomcold room evap icing
Presenter cue: Walk through defrost sequence, infiltration, fan/airflow and drainage evidence. Keep the result as a ranked troubleshooting trail, not an automatic root-cause declaration.
High condensing / discharge condition
The condensing/discharge condition is higher than intended and heat rejection needs structured checking.
Condensing Unitcond unit high discharge
Presenter cue: Check heat-rejection surface, condenser fan/airflow, entering condition and qualified refrigerant-side evidence without inferring charge from one snapshot.
ENGINEERING BOUNDARY
The POC must demonstrate disciplined diagnosis—not magic diagnosis.
HVACR Studio should not claim that one temperature, pressure or visual clue proves refrigerant charge, leakage, restriction, compressor condition, food/product release or compliance. The demo is strongest when it shows how observations, checks, action and retest remain separate and traceable.
