Condenser fluid, comprising vaporized working fluid and non-condensable gases, is treated by extracting fluid from the condenser (16A) and pressuring the fluid to liquefy the vaporized working fluid therein in such a way that the non-condensable gases are separated from the working fluid and can be vented from the extracted fluid. A piston (36) draws the vaporized fluid into a chamber (32) through an open valve (33). The valve is then closed and the fluid is compressed by the piston (36), the fluid being cooled by a cooling coil (53), so that working fluid condenses, whereupon the non-condensed gases are vented (valve 39). The valve (33) is then opened so that the working fluid can flow back into the condenser (16A). |
