Cold Chain / Truck Shops
A technician and refrigeration knowledge base for repair shops and cold-chain carriers
The Phak AI technician knowledge base keeps refrigeration unit manuals, driver guides, QC checklists, and know-how captured from senior technicians in one place. New technicians and drivers ask in Thai from their phones on site. Every answer cites its sources by document. Years of know-how stay with the organization, even when people leave.
How do I pre-cool the box before loading frozen goods?
Per the manual, run the unit until the box hits the job sheet temperature, then check the display before opening doors.
Source: Cold-chain driver manual, section 3Correct. If the display has not reached the setting, tell a technician before loading.
Why refrigeration technician know-how is at risk
Know-how sits with senior technicians
Years of install and troubleshooting tricks for refrigeration units live in the heads of a few senior staff.
Technicians are short, training is slow
Seniors stop work to teach the same things again each time a new technician joins.
New drivers need specific steps
Pre-cooling and loading frozen goods have steps that cannot be missed. A mistake spoils goods and leads to claims.
Documents are scattered
Manuals for many unit models, QC checklists, and vehicle modification papers sit in different binders and drives.
How to build a technician knowledge base
Start with documents you already have, then add senior know-how one topic at a time.
Gather existing documents
Refrigeration unit manuals, driver guides, and QC checklists in PDF, Word, Excel, or image form go into the knowledge base, with Google Drive sync.
Capture senior know-how
Interview senior technicians on frequent topics, write it up, and have the lead technician review it before use.
Set role-based access
Technicians, drivers, and QC staff see documents for their own work, and every question is logged.
Ask from the job site
Ask on a phone or in the team LINE group. The assistant answers from documents and cites its sources, the same idea as RAG. If it is not sure, it does not guess.
Questions technicians and drivers can ask
What we measure in a technician knowledge base
Measures agreed together, tracked with your own numbers.

Frequently asked questions
How does know-how in technicians' heads get into the system?
During setup, the Phak AI team interviews senior technicians on frequent topics and writes it up. The lead technician reviews it before the team can ask about it.
Do drivers see the same documents as technicians?
You decide. Role-based access lets each group see only documents for their own work, and every question is logged.
When a manual is revised, do answers change too?
The assistant answers from what is in the knowledge base. When you update a file or sync from Google Drive, answers use the new version and name the document each time.
