The problem: A piston-type reciprocating compressor has had valve damage, or the valves just are not sealing for some reason. This low-temperature refrigeration system has a thermostatic expansion ...

Compressor surge occurs when flow is too low with respect to the change of pressure of the compressor or when ΔP is too high with respect to the flow. A decreasing flow coupled with an increasing ∆P, ...

Service technicians will often experience frost on a suction line or on the compressor in some refrigeration applications. Thinking that liquid refrigerant must be present because there is frost is a ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...
