DEVICE AND METHOD FOR REMOVING A GAS FROM A SYSTEM, SYSTEM FOR EVAPORATING, AND HEAT PUMP

摘要

The invention relates to a device for removing a first gas from a system (2) having a second different gas, comprising a collecting container (10) for collecting the first gas, the collecting container (10) having a variable inlet opening (5) for admitting the first gas into the collecting container (10), wherein the inlet opening can be brought to communicate with the system, and having a variable outlet opening (4) for discharging the first gas from the collecting container (10), wherein the variable outlet opening is not in communication with the system, and having a unit (1) for generating a pressure in the collecting container (10), said pressure being greater than a pressure of an atmosphere outside the variable outlet opening, wherein the inlet opening (5) and the outlet opening (4) are configured such that in an expulsion mode at a pressure in the collecting container (10) that is greater than a pressure in the atmosphere the inlet opening (5) has a higher fluid resistance than the outlet opening (4) such that the second gas can be discharged from the collecting container (10) via the outlet opening (4), and that in a collecting mode the outlet opening (4) has a higher fluid resistance than the inlet opening (5).
