Abstract:
1. A condenser comprising: a housing having a vapor inflow port connectable to a discharge portion of a compressor, a first degassing chamber, in the housing, communicating with the vapor inflow port, and a second degassing chamber, in the housing, arranged above the first degassing chamber across a partition portion; a first degassing device for degassing and concentrating air from the first degassing chamber and discharging the concentrated air to the second degassing chamber; and a second degassing device for degassing and concentrating air from the second degassing chamber and externally discharging the concentrated air, the condenser shedding a cooling fluid in the first degassing chamber via the second degassing chamber in the housing and causing vapor flowing into the first degassing chamber through the vapor inflow port to adhere to the cooling fluid so as to condense the vapor, wherein: the condenser comprises a passing portion for permitting the cooling fluid to flow from the second degassing chamber to the first degassing chamber; the first degassing chamber is separated from the second degassing chamber by the cooling fluid in the passing portion, and the passing portion has a pressure head space for containing a specified volume of cooling fluid so as to absorb a variation in a pressure difference between the first degassing chamber and the second degassing chamber.
