| 摘要 | 1,114,009. Refrigerating. CARRIER CORPORATION. 1 Nov., 1965, No. 46161/65. Heading F4H. In an absorption system employing octyl alcohol as an additive to water and lithium bromide solution, points at which liquid alcohol tends to accumulate are provided with heating means to vaporize the alcohol. The illustrated system includes a gas fired generator 10, a separator 20, a condenser 11, an evaporator 12 and an absorber 13. The absorber tube bundle 46 is surrounded by a pan 48 which discharges through a pipe 49 into the outlet 64 of an absorber sump 50. A line 54 for passing strong and recirculated solution to the absorber passes at a shallow angle, Fig. 2 (not shown), through the absorber sump 50 to vaporize alcohol collecting on the surface of liquid in the sump. The chilled liquid output line 28 from the evaporator tube bundle passes in similar manner through the evaporator sump 34 to evaporate alcohol therefrom. An electric heater 72 is provided at the surface of liquid in a line returning liquid from the absorber and the separator to the generator. As an alternative to the heater 72, the return line may be run in heat exchange with the generator. Electric heaters may be used to heat the sumps 34 and 50, as may lines 24 or 18. | ||||||
| 权利要求 | 12. A METHOD OF OPERATING AN ABSORPTION REFRIGERATION MACHINE WHICH INCLUDES AN ABSORBER SECTION, AN EVAPORATOR SECTION, A GENERATOR SECTION AND A CONDENSER SECTION CONNECTED TO PROVIDE REFRIGERATION, WHEREIN SAID MACHINE CONTAINS AN ABSORBENT SOLUTION, A REFRIGERANT, AND A PARTIALLY UNDISSOLVED, RELATIVELY VOLATILE, LIQUID ADDITIVE WHICH COMPRISES THE STEPS OF PASSING ABSORBENT SOLUTION AND REFRIGERANT THROUGH SAID MACHINE TO PRODUCE REFRIGERATION; COLLECTING UNDISSOLVED LIQUID ADDITIVE IN A REGION OF SAID REFRIGERATION MACHINE; AND SUPPLYING HEAT TO SAID REGION TO VAPORIZE UNDISSOLVED LIQUID ADDITIVE ACCUMULATED IN SAID REGION SO THAT SAID VAPORIZED ADDITIVE IS ENABLED TO PASS FROM SAID REGION TO ANOTHER REGION OF SAID REFRIGERATION MACHINE. |
