Abstract
The invention relates to an assembly comprising a vacuum pump and a chamber, wherein a suction tract extends between the chamber and the vacuum pump. The vacuum pump is a liquid ring machine. According to the invention, a liquid outlet is arranged in the suction tract in order to add liquid to gas sucked in from the chamber. The invention further relates to a method for evacuating a chamber filled with vapor. According to the invention, the vapor is condensed by introducing additional liquid into the suction tract, thus by co-condensation. By supplying liquid selectively only when liquid is required for the condensation of the vapor, water is saved.
Claims19
An assembly produced from a vacuum pump (16) and a chamber (15), wherein an intake tract (17) extends between the chamber (15) and the vacuum pump (16) and wherein the vacuum pump (16) is a liquid ring machine, characterized in that a liquid outlet (18) is arranged in the intake tract (17) in order to mix gas sucked out of the chamber (15) with liquid.
A method for evacuating a chamber (15) filled with vapor, by means of which method a vacuum pump (16), which is connected to the chamber (15) by means of an intake tract (17), is operated in order to suck the vapor out of the chamber (15), and by means of which a liquid is supplied to the intake tract (17) such that the vapor condenses.
