Patent ID: 7802430

Claim:
Novel pressure control system technology comprising: a condenser steam-air mixture exhaust simulator having a mixer with a steam inlet pipe and an air inlet pipe, heating means to vaporize water that enters the steam inlet pipe, flow regulating means and pressure and temperature sensing means in both steam and air inlet pipes, flow regulating means, pressure and temperature sensing means and a vacuum pump to adjust pressure in a steam-air mixture outlet pipe of the mixer matching the condenser steam-air mixture exhaust; a pressure control device for condensing steam in the steam-air mixture inside the device, the pressure control device having an inlet of steam-air mixture from the condenser steam-air exhaust simulator, an inlet for chilled water with spraying means and an outlet for uncondensed air-steam mixture leaving the pressure control device; a variable speed pump circulating water through a chiller for cooling water used in the pressure control device to condense steam of the steam-air mixture from a condenser exhaust; and a drain line to remove condensate from the pressure control device.
