Device for driving water out of aqueous solution in vacuum vessel, e.g. for refrigerators, has Roots blower pump connected on suction side to gas volume above solution, on pressure side via condensation loop in solution to water outlet

摘要

The device has a Roots blower pump (2) that is connected on the suction side to the volume of gas (4) above the solution in the vacuum vessel (1) and on the pressure side via a condensation loop (7) immersed in the solution to a water outlet (8). The Roots blower pump is provided with pre-inlet cooling.
