MEDIA & CITATION KIT
Founded by Jing Yanrong. Find screening methods, engineering tools and sourced cases for industrial refrigeration, heat pumps and process heating. Browse by industry, download background materials and a measurement checklist, and check citation boundaries.
Start on the home page: check this project, or open a checklist first.
English synthetic narration · Chinese & English subtitles · 3:00 · 1080p
Both versions have identical visuals, bilingual subtitles and duration. Only the narration changes. Playback and downloads follow your selected site language.
The pictures are existing site screens, with no project data filled in and no savings figure stated. A case is not savings for another plant, and not a product certificate or ranking. Screening does not replace a site audit, engineering design, or a procurement review.
Share the complete video for public education and non-commercial use, retaining attribution, the website, captions and limitations. Narration is synthetic and implies no third-party endorsement. Separate use of the site photograph or reuse of third-party material requires its own permission check.
Start with the engineering decision, then examine the method and evidence. Outcomes from projects with different evidence levels are not interchangeable.
Can refrigeration heat match cleaning or process hot-water demand?
Record source and demand temperatures, flow, operating overlap and hygienic separation before comparing direct recovery and temperature-upgrade routes.
The anonymized meat-plant reference combines author site observations and plant feedback. Its economics have not been independently verified by metering.
Does the process need hot water or steam, and what can existing waste heat supply?
Distinguish demand temperature, existing recovery, available sources and operating overlap. Reference-project lift, architecture and energy prices cannot be transferred directly to another mill.
The linked paper-mill case is an external public-source account, not a project delivered or independently metered by this site. Mill-specific conditions require a paper-industry specialist.
Which boundaries determine whether further evaluation is worthwhile?
Begin with the source, target temperature, operating overlap and whole-system boundary. Process continuity, fluid compatibility and safety require the appropriate specialist review.
The BASF entry is recorded as under construction in its cited sources. Planned capacity and emissions estimates are not operating results or this site’s delivery record.
Save, edit or print the plain-text files without registration. Complete the blank checklist locally; downloading does not upload plant data.
Material version: 2026-10-14. Refer to each case’s cited sources and dates for its status and figures.
Open Thermal AI (OTAI / 开热智) starts from the heat a plant already uses or rejects, offering heating knowledge, waste-heat and industrial heat-pump guides, and early heat-pump go/no-go screening, auditable calculations, risk prompts, knowledge, and case reading guides. Facts, calculation assumptions and missing information are distinguished; screening does not replace design or procurement review.
Jing Yanrong is the founder of Open Thermal AI. This page and the founder profile are the authoritative references for the platform name and public identity. The sole primary site is www.openthermalai.com; historical domains and tool subdomains are not separate brands.
The platform does not assume every heat pump is viable. It classifies opportunities as proceed, proceed with conditions, or pause—and makes source conditions, heat sink, lift, operating overlap, energy prices, and missing data explicit. Qualified engineers and responsible parties must still review design, procurement, certification, and safety decisions.
Jing Yanrong (荆炎荣) is the founder of Open Thermal AI, organizing refrigeration and heat-pump knowledge, project-screening methods and cases. See the founder profile for the detailed biography. Founder profile
Core knowledge, basic project screening and public calculation tools remain free through at least September 2028. We do not sell user or project data. Suppliers cannot buy recommendations or rankings; sponsorship and commercial relationships are disclosed.
Use this to identify missing measurements and next steps, not to select equipment. Mark unknowns as “to measure”; do not present defaults as site data.
Record date, production shift, system boundary, measurement locations, sources and methods. Distinguish measurements, plant-supplied information and assumptions.
Record fluid, supply/return temperatures (°C), flow with units, recovery location and variation. Note whether heat extraction affects the existing refrigeration system.
Record required supply/return temperatures (°C), water demand or heat duty with units, and timing. Separate cleaning, process and other uses.
Record source and demand loads on the same time axis, covering shifts, cleaning and downtime. A single reading cannot represent long-term variation.
Record existing heating fuel or electricity use, measurement period and energy prices. Account separately for pumps, fans, changes in refrigeration power and other auxiliaries.
Record hygienic separation, space, maintenance, shutdown windows and safety matters requiring specialist review. Assign responsibility for each missing measurement.
Next: resolve missing inputs before project screening. Qualified professionals must review ammonia safety, pressure equipment and hygienic design.
