Title: A method of removing parts of a refrigerating machine
IPC: F25B15/06
Filed: 1964-12-21
Abstract: 1,018,640. Refrigerating. TRANE CO. Dec. 21, 1964 [Aug. 21, 1964], No. 51856/64. Heading F4H. A method of removing a pump-motor from the absorbent and/or refrigerant recycling circuits in a continuous cycle absorption system comprises providing liquid trap(s) in said circuit(s) below said pump(s), and admitting a gas which is inert with respect to the absorbent and refrigerant into the system until the sum of the gas and hydrostatic pressures at a level in the circuit(s) below that of the pump(s) is substantially atmospheric so that the pump and/or motor may be removed without removing absorbent or refrigerant from the system. As shown, the suction and discharge lines of the refrigerant circulating pump 42 have liquid traps 66 and 68 respectively; similarly traps 70, 72 are provided on the suction and discharge sides of the absorbent circulating pump 52. When the pump motor 58 or the pump and motor are to be removed, nitrogen from a vessel 88 is admitted to the shell 10 of the system until the sum of the gas pressure in the shell and the hydrostatic pressure in suction line 54 at a level above trap 70 and below that of the pump inlet is substantially atmospheric. Pump 52 is then vented to atmosphere through vent 96 so that the liquid in that portion of the suction line between trap 70 and the pump inlet falls to said level, as shown. A sight glass 92 is provided for observing the liquid level. A valve 80 in a cross-over conduit 78 is then opened to equalize the liquid levels above traps 70 and 72 and the pump and/or motor is then removed without penetration of atmospheric air into the shell 10. The pump 42 and its motor may be similarly removed and if it is desired to remove pumps 42 and 52 simultaneously a valve 100 in a conduit 98 connecting traps 66 and 70 is opened to equalize the liquid levels above said traps. When the pump is reinstalled the air trapped at the location of the pump may be expelled by admitting more nitrogen to the shell to force said air out through vent 96 or by connecting a vacuum pump to the vent. The system is purged of nitrogen by a pump 34 before commencing operation.
