Page 31 - ... carried over from the rectifier to the condenser. It will be seen from these curves that the economy of the absorption machine is much better for all conditions than that of a simple non-condensing engine driven compressor, and that at between 8 and 10 Ibs. gauge suction pressure that the economy of absorption and the compound condensing engine driven compressor is the same, and that at suction pressures above 8 to 10 Ibs.
Page 166 - ... slackening, as it latches — the soft hemp gasket in the joint is always in sight. A mere touch, frees and opens it from either side. Old style doors when they work badly or leak, must be eased, thus forever destroying their fit. A slight readjustment of the door frame of these doors, restores them to perfect fit and freedom in a minute, at no expense. As they do not stand in the doorway when open, its width can be six inches less than old style doorways — an important economy in refrigeration.
Page 174 - CHICAGO *T*HIS work presents, in a convenient form, the rules, tables, •^ formulae and directions which are needed by refrigerating machinery engineers, ice manufacturers, cold storage men, brewers, meat freezing establishments, packers, contractors and all others interested in the practical application of refrigeration. It is, in fact, designed to give ready and plain answers to most of such questions as are daily occurring in any one of the different branches of practical refrigeration.
Page 22 - The old saying that a chain is no stronger than its weakest link is illustrative of the weakened link between life and death.
Page 166 - B shows wooden bevelled threshold 1 ^ inches thick. Connects lower ends of door frame, forms part of it and is let down into the floor. No feather edge, no jolt, no splinters. For warehouses. Accommodates Trucks. Fig. C, concrete floors: shows lower ends of door frame extending down into the floor 3 inches, and connected by angleirons extending across doorway from one side to the other, below the surface.
Page 166 - DOORS DOORS are just a big valve, and are a weak point in all cold storage. Insulation is important, tightness and quickness are vastly more so. Leaks are an endless expense. Doors that bind and work badly are shut only when the workman can find no excuse for leaving them open, which is seldom, if ever. The diagrams show a patented construction, contrived to avoid these troubles. The thick portion of the door fits loosely, so that considerable change of size, form and position, due to wear, swelling,...

Page 23 - In general, the following fundamental rules can be laid down for an absorption -machine to give best results. The generator should have ample liquid evaporating surface to make dry gas. This is on the same principle that vertical steam boilers do not give as dry steam as do horizontal steam boilers. As the partial pressure of the water vapor in the gas to the rectifier bears a direct relation to its temperature, and also a direct relation to the weight of water...
Page 119 - The ordinary so-called exhaust steam machines operate with exhaust steam from inefficient auxiliaries. Such operation is just the same as if the plant operated with economical auxiliaries and then used the additional steam required directly from the boiler to make up the difference.
