<p>A test device for a compressor has a valve and ducting connected to the valve. A flow nozzle connected to the ducting has a corresponding coefficient of flow. A pressure sensor connected to the flow nozzle measures a pressure of a working fluid, and a flow rate of the working fluid is calculated using the pressure and the coefficient of flow. A method for testing a compressor includes operating the compressor at a first power level, measuring a flow rate of a working fluid at the first power level, adjusting a pressure of the working fluid to equal a first predetermined pressure, and measuring operating parameters of the compressor at the first power level. The method also includes adjusting the pressure of the working fluid to equal a second predetermined pressure and measuring operating parameters of the compressor at the first power level with the pressure of the working fluid at the second predetermined pressure.</p> |
