SINGLE EVAPORATOR FOR ABSORPTION MACHINES Filed Aug. 28, 1950 //71/en for:
Erich K/nclermann Patented Feb. 20, 1934 UNITED STA SINGLE EVAPORATOR FOR ABSORPTION MACHINES Application August 28, 1930, Serial No. 478,496,
" and in Germany September 3, 1929 1 Claim.
My present invention relates to evaporators such as are used in conjunction with refrigerating machines working on the absorption principle, and particularly to the type in which an evaporating system consisting of individual chambers is arranged to receive the liquefied refrigerant gradually'in the said individual chambers and likewise convey from chamber to chamber the solvent carried along and ultimately return it again from the last chamber to the absorber. Various constructions of this evaporator consisting of individual chambers, have proved satisfactory in practice, and my present application relates to novel embodiments of such an evaporator which proved particularly suitable.
Evaporation is favoured by a large superficial area of the liquefied refrigerant collected in the evaporator.
In order to obtain a large superficial area of the evaporator composed of individual chambers, I have found it sufiicient and advantageous to employ a relatively small number of individual chambers or containers, of the proper dimensions to provide the desired large aggregate superficial area. These containers may be of any suitable shape, for instance cylindrical or spherical. These individual containers or vessels are connected with pressure-compensating or pressureequalizing means, for instance a pipe in permanent communication with the upper portions of the vessels, as by means of connection branches. Using a relatively small number of such vessels also has the advantage of reducing the number of the connection branches leading to the pressure compensating pipe, so that it is possible to produce the whole apparatus in a more economical manner. r I
In the drawing. an arrangement according to the invention is illustrated by way of example.
Figure 1 is a vertical section through an evaporator system consisting of individual chambers according to the present invention, and Figure 2 is a similar view of another embodiment.
Referring to-Figure 1 there is shown such an evaporating system consisting. of individual chambers, in which the letters a, b and c designate separate containers, of which the vessels b and 0 through the medium of their branches 3' extend close to the upper walls of the compensating pipe 4, while the branch pipe of the vessel a lies flush with the lower surface of the compensating pipe. The communication between the containers 1: to c is eflected by means of the connecting pipes 11, which counting in the se- TES PATENT OFFICE quence in which the individual containers or vessels of the evaporator are filled with ammonia, extend from the bottom portions of the first and the second containers a and b respectively into the upper portion of containers b and c re the second and the third spectively, efiecting in this manner a communication from container to container. The third co the bottom portiono nnection pipe 11 starts at f the last container c and leads to the absorber in the manner indicated in the drawing, efiecting at the same time a compipe 4.
A further embodiment according to the invention is shown in Figure 2, in which the individual containers have the form of vessels such as re-- ferred to above.
These separate containers are connected by means of open pipes 11, which start from the bottom of the container, as shown, but
which traverse said 0 upper portion of the dium is conveyed from the last container '0, which is likewise connected to the absorber. connection pipes from ontainer draining into the next container. Ihe meto the compensating pipe,
This arrangement of the open container to container will promote the evaporation efiect and in addition it offers the advantage of great saving of space.
The said open connecting tubes may be of large diameter, without encroaching in any way upon the available space.
let of the system to the absorber.
rangement set forth,
With the arwhere the outlets of the pipes 11 are at a higher level than their inlets, a simultaneous emptying of all the vessels (1, b, 0 will take place, by a sort of siphon action, whenever there is a discharge of the contents of the last vessel, 0, into the connection leading to the absorber.
I I claim:
In apparatus of the of evaporating vessel passage of fluid from class described, a plurality s, and connections for the one vessel to the next, each of said connections having its inlet at the lower portion of one vessel,
and its outlet at the upper portion of the next vessel, the outlets of said connections being at approximately the same level with each other and with the outlet of the entire system formed by said vessels.
