- French-speaking HVAC design engineers and technical offices
- Worth noticing
- Its homepage groups calculators across hydraulics, air handling, refrigeration, hot water, acoustics, and more, and says each includes a course.
Field notes
The collection is divided into technical subjects, with listed tasks ranging from expansion-vessel sizing and fan-duct pressure loss to hot-water charging time and sound-level addition. La Calculerie describes the tools as aids rather than engineering services and tells users to verify results against manufacturer instructions and applicable regulations.
