Calculator · portable AC / BTU
Portable AC BTU/kW
Estimate portable AC capacity in kW and BTU/h for offices, plant rooms, events, kitchens and workshops.
For fast temporary cooling equipment selection.
Guided job flow
Portable AC Event & Server-Room Power Plan
Estimate cooling, start current, exhaust duct losses, condensate handling and generator demand for temporary cooling.
Flow steps
- Choose server room, event, office, kitchen or workshop.
- Estimate cooling kW/BTU and spot load.
- Check compressor start current and generator kVA.
- Derate for exhaust ducting and plan condensate.
- Export a start sequence and power note.
Tools in this flow
Tool indexCalculator · spot cooling / server room
Spot cooling load
Estimate spot cooling for server rooms, production lines, events and overheated work zones.
For targeted cooling where cooling the whole building is unnecessary.
Calculator · start current / AC
AC start current
Estimate start-current pressure on breakers or generators for portable AC and compressor loads.
For generator jobs, weak supplies and nuisance MCB trips.
Calculator · generator / kVA
Generator kVA + start current
Size a generator for portable AC, dehumidifiers, fans and heaters with a start-current allowance rather than only running watts.
For event sites, emergency cooling, flood drying and temporary power jobs.
Calculator · AC exhaust / ducting
AC exhaust derate
Estimate cooling performance loss from long exhaust duct runs, bends and recirculation risk.
For temporary AC installs where hot exhaust routing is the real constraint.
Calculator · portable AC / condensate
AC condensate plan
Plan tank emptying, gravity drain or pump route for unattended portable AC operation.
For overnight cooling, plant rooms and temporary office setups.
