Proper Refrigeration Piping Installation Practices for HVACR

Dry nitrogen is used for pressure testing and purging, and then a proper vacuum of the system should be done. Pressure testing includes a test that the system will hold a charge of nitrogen (300 to 400 p.s.i.g but follow manufacturers instructions for maximum pressure testing limitations - remember the evaporator coil pressure limitations also

Compressor - Wikipedia

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while

Water Handbook - Preboiler & Industrial Boiler Corrosion

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

External Pressure – Pressure Vessel Engineering

Jul 05, 2012 · External pressure calculations are more difficult with more than one source of external pressure – a typical example is a vessel with an internal vacuum and pressure in a jacket. The cases with the stay rods, half pipe jackets and dimple jackets are the simplest – first calculate the complete vessel for the vacuum condition as if the jacket
