Final answer:
The diffuser collects high-pressure air from the compressor and delivers it to the combustion chamber in a centrifugal type compressor. It functions as part of a refrigeration cycle involving condensation and pressure reduction before returning to the evaporator coils.
Step-by-step explanation:
The component that collects high-pressure compressor air and feeds it to the combustion chambers in a centrifugal type compressor is commonly known as a diffuser. After the electrically driven compressor, which operates with work input W, increases the pressure and temperature of the gas, it forces the gas into condenser coils within a heated space. Here, the high temperature of the gas compared to the room's temperature allows for heat transfer, leading to the condensation of the gas into a liquid. The liquid then passes through a pressure-reducing valve, usually back to the outdoor evaporator coils. In some cooling systems, the evaporator and condenser coils can swap roles, reversing the fluid's flow direction. This heat exchange and refrigeration cycle is essential in applications ranging from domestic air conditioning to industrial processes.
