This tool calculates the minimum water vapour needed to move room air from its initial state to a target temperature and relative humidity. Product, racks, walls, door openings, leakage and condensation remain visible as additional site loads.
Room air replaced by doors and leakage per hour, assuming incoming air is at the entered initial condition. Zero keeps the result at the air-fill lower bound.
Product, racks, surface condensation or another measured load. Do not guess; use 0 if unknown.
No automatic loss factor is invented; a long or uninsulated line triggers technical review.
Preliminary result
Mathematical preliminary candidate
ST-1 · 12 kg/h · 10 kW
Entered load is within ST-1 nominal capacity. Unentered product, surface and leakage loads still require final review.
Product/rack/surface load is 0. This is the physical lower bound for air only; actual room demand may be higher.
Line length was not converted into an invented loss. Verify material, diameter, pressure-temperature rating, slope, insulation and condensate drainage.
The kg/h result applies only to the target time and loads you entered. The model is a capacity comparison, not a guarantee of uniform humidity, recipe performance or product outcome. Commission the empty and loaded room with measurements.
Dough recipe and temperature, rack mass, panel and door leakage, cold-surface condensation, air circulation, sensor position, control hysteresis and steam-line losses cannot honestly be reduced to one coefficient without measurements.
In a verified Stilsan field application, ST-1 was used in a room with about 25 m² floor area and 2.5 m height. One installation is not a universal sizing rule.
We have real field experience with ST-1 in an approximately 25 m², 2.5 m-high bakery proofing room. It is not a universal guarantee without target temperature/RH, climate, product load, doors, insulation and line data.
A warm, humid start can look satisfactory quickly; a cold, dry start can take longer. A 2–10 minute field observation is not a guaranteed target-RH time.
The verified application used low-level distribution to support the natural rise of warm humid air. Outlet layout must still consider circulation, safety and condensate.
A suitable controller can call for steam while a separate heater or climate unit manages temperature. Electrical and control design must be verified for the project.
