single-stage compressor

[′siŋ·gəl ¦stāj kəm′pres·ər]
(mechanical engineering)
A machine that effects overall compression of a gas or vapor from suction to discharge conditions without any sequential multiplicity of elements, such as cylinders or rotors.

single-stage compressor

A centrifugal compressor having a single impeller wheel, with vanes either on one or on both sides of the wheel. Also, an axial-flow compressor with one row of rotor blades and one row of stator blades. Axial-flow compressors are normally multistage. A single-stage compressor achieves the overall pressure ratio in one single operation (e.g., by a centrifugal impeller or a single row of axial blades). See centrifugal compressor.

Due to weight limitations the system is equipped with single-stage compressor, which operates at very low evaporation temperatures.
While the design of the mixed refrigerant system test apparatus is related to the two-stage cascade refrigeration system shown in Figure 1, it only uses one single-stage compressor. A Copeland CF12 reciprocating compressor was selected for the mixed gas refrigeration cycle and is modeled using empirical performance data at varying operating conditions provided by the manufacturer (Emerson 2010).
Because this program tested only a single-stage compressor, the aerodynamic work input (and power) remained the same between the adiabatic and diabatic tests.
As a result, the supply pressure required by the probe is reduced dramatically and a single-stage compressor, comparable to a small refrigeration compressor, can be used to energize the system.
