A
simple definition of a compressor is a device used to pressurize a fluid,
including liquids and gases. There are many different kinds of
compressors, but typically the main purpose of using a compressor is to
raise the pressure of a liquid or gas. Compressors are found in both gas
power cycles and vapor compression refrigeration cycles.A compressor converts shaft power to a rise in enthalpy of a fluid. The fluid, often a gas, enters the compressor at a low pressure (low enthalpy) and exits at a high pressure (high enthalpy). The rotating shaft is attached to a blade assembly. The rotating blades push on the gas and increase the pressure, thereby increasing the enthalpy. Compressors are continuous flow processes, and can be either axial or radial.
