Title: Improvements in absorption refrigerating apparatus
IPC: F25B15/02
Filed: 1929-06-12
Abstract: 336,275. Fitzpatrick, H. D., (Naam looze Vennootschap Kodowa Refrigerator Co., and Bargeboer, A.). June 12, 1929. Refrigerating, absorption machines and systems for.-Circulation either of the condensed refrigerant or of the strong or weak liquor is effected by a pump actuated by refrigerant vapour which is used to produce cooling in the machine. Refrigerant vapour passes from the generator 2, Fig. 1, through the pipe 13 to the double-acting piston pump 5 and, in the position of the regulating slide 36 shown in Fig. 2, effects the upstroke of the piston 31 and the discharge through the pipe 14 to the water-cooled condenser 4 of the vapour previously admitted to the cylinder from the pipe 13 connected to the generator. The flow of refrigerant from the condenser to the evaporator 8 is controlled by a valve 6 controlled by a thermostat 7 in the refrigerator. Also, during the upstroke nf the piston, weak liquor previously admitted into the intermediate plunger chamber above the cylinder through the port 83 and the pipe 11 connected to the generator is discharged through the pipe 20 to the water-cooled absorber 9 while strong liquor previonsly admitted to the top plunger chamber from the absorber through the pipe 21 is discharged through the pipe 12 to the generator. The pipes 11, 12 form a heat exchanger. When the piston reaches the top of its stroke, the slide is suddenly moved to its lower extreme position through the toggle mechanism and the spring 48 connecting the lower ends of the pistons and the slide. In this position, refrigerant vapour effects the downstroke of the piston and strong and weak liquor are drawn into the upper and intermediate plunger chambers respectively, while the vapour on the lower side of the piston is discharged to the condenser. The generator is heated by a steam coil 73 connected to a gasheated boiler 1 the supply of gas to the burner 70 of which passes through a water-seal 75 and is controlled by a valve 80 dependent on the pressure in the boiler. An excess pressure in the boiler results in the flooding of the seal through the pipe 78. The thermostat in the refrigerator may control the gas supply to the burner, and the pump 5 may be arranged either between the condenser and the evaporator or between the evaporator and the absorber.
