ENGINEERING GUIDE

Use the Receiver Size for Compressor Start/Stop Control to size storage to limit starts per hour between pressure setpoints. The calculator uses Compressor capacity, Average demand, Cut-out pressure, Cut-in pressure and Desired minimum loaded/unloaded cycle and reports required receiver volume; predicted cycles.

How to interpret the result

Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are required receiver volume; predicted cycles. Change one input at a time when comparing scenarios so the effect of each variable remains clear.

Formula and methodology

PneumaForge applies this verified method: Size storage from compressor excess/deficit over cut-out/cut-in pressure band and desired minimum cycle duration; report predicted starts/hour. The functional engine is shared with related tools in the receiver-cycling family, while this page solves the specific intent represented by air receiver size for compressor cycling calculator.

Size storage from compressor excess/deficit over cut-out/cut-in pressure band and desired minimum cycle duration; report predicted starts/hour.

Variables and inputs

  • Compressor capacity
  • Average demand
  • Cut-out pressure
  • Cut-in pressure
  • Desired minimum loaded/unloaded cycle
  • Air temperature

Worked example

Reproducible example: start with the calculator's default values (Compressor capacity = 3000; Average demand = 1500; Cut-out pressure = 8; Cut-in pressure = 6) and calculate the result. Then change the variable most relevant to your application and compare the new required receiver volume; predicted cycles against the baseline.

Assumptions and limits

User supplies compressor delivery, demand and cycle limit; do not hardcode switching limits as universal.

Engineering tips

  • Use absolute pressure internally even when the interface accepts gauge pressure.
  • State the thermal assumption for fill and blowdown calculations.
  • Receiver volume cannot replace adequate compressor capacity for sustained demand.
  • Keep the inputs used for receiver size for compressor start/stop control on a consistent engineering basis before comparing alternatives.

Frequently asked questions

What does the Receiver Size for Compressor Start/Stop Control calculate?

It is designed to size storage to limit starts per hour between pressure setpoints. The reported outputs are required receiver volume; predicted cycles.

What inputs does the Receiver Size for Compressor Start/Stop Control use?

The calculator uses Compressor capacity, Average demand, Cut-out pressure, Cut-in pressure and Desired minimum loaded/unloaded cycle. Only use values that represent the same operating condition or design case.

What formula or method is used?

The calculation follows: Size storage from compressor excess/deficit over cut-out/cut-in pressure band and desired minimum cycle duration; report predicted starts/hour. The page also states the assumptions that define where the method is valid.

Which assumptions can affect the result?

User supplies compressor delivery, demand and cycle limit; do not hardcode switching limits as universal.

Can I use different units?

Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
