Abstract
A plurality of upstanding cooling ducts in a condenser are closed at their upper ends and only a lower header which is disposed at the lower ends of the cooling ducts communicates a tank with the cooling ducts. In another embodiment, a check valve and a gas pump are disposed in an upper conduit connecting the tank to a common upper header communicating the cooling ducts with each other at their upper ends so as to discharge the noncondensable gas from the condenser to the tank. Further, a sensing device may be disposed to sense the interface between the noncondensable gas and the vapor refrigerant in the cooling ducts, and a controller may be disposed to compare the interface level sensed by the sensing device with a reference interface level set in the controller to control the gas pump such that the actual interface level is in conformity with the reference interface level.
