Many refrigeration compressors incorporate a suction service valve and a discharge service valve. These are used to allow refrigeration gauges to be attached to the system; and, if needed, they are ...

The hottest temperature point in a refrigeration or air conditioning system is on the back of the compressor’s discharge valve, as shown in Figure 1. However, since this point cannot be measured by a ...

Years ago, it was common for shops to have a central power source that drove all the tools through a system of belts, wheels and driveshafts. The power was routed around the work space by mechanical ...

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, ...

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, ...
