REFRIGERATING AIPARATUS.
Application led November 1, 1928, Serial No.` 316,530, and in the Netherlands August 4, 1927.
This invention relates to a refrigerating device, for instance ofthe absorption type,
' depending for its action upon the alternative evaporation and condensation of a Huid rclfrigeratmg agent.
and thereby the efficiency of the refrigerating.
device increased.l
Further according to the invention the refrigerating device may be so constructed,'
that the refrigerating agent yflows in condensed form from the condenser into the separately mounted tank. Moreover, ac-
coi-ding to the invention, the separately 'mounted tank may be connected by a plurality of conduits to a plurality of evaporators, while further the said conduits may vbe branched oii'.' `from a single main or collecting conduit, coming from the tank.
The discharge rfrom the said evaporators may also be obtained by means of a plurality of conduits connected to a common return Y conduit, leading back to the boiler. By this arrangement, it is possible to regulate the low temperature to e produced in the 'cooling casing, for instance, by inserting in the v conduit between the separate tank andthe .tains a constant low temperature in the casl evaporator in the casing a throttling device `which may comprise a reducing valve and which maybe located within the casing and Vmay be operable from the exterior.
When using a plurality of evaporators each conduit leading to an evaporator may be provided with a throttling device. This regulation keeps the evaporation in the cas- 1ng or 1n each casing constant, that 1s, 1t malning or casings, which is not possible in the systems now used, in which the tank is contained in the cooling space.
Another feature of the invention resides in the use of a single condenser for a plurality of evaporators.
In order to simplify the assembling of the various parts, and to prevent leakage, the
ing illustrating one embodiment of thein- 60 vention.
The figure is a schematical view of the re'- rigeratin device.
In the rawings, the nunieral 1 designates Aa boiler, thevapor space of which is connected by a conduit 2, provided with a valve 3, to a condenser 4 which in turn is connected to a reservoir or storagetank -5 through the conduit 6.
The numeral 7 denotes anevaporator in 70.' the usual coil :form contained within'l a cooling space 8. One end of theevaporator 7 is connected with the tank 5 by means of an inlet conduit 9 and a branch conduit 10 connected therewith. A regulating or throt- A tlingvalve 11 connected` in the conduit 10 leading to the coil is locatedwithin the cooling space with the coil and may beV operable from outside -of the casing by extension or connecting means, not shown.
A return or discharge conduit 12 connects with the lower end of the coil 7 with the boiler 1 through the extended part 13 of the discharge conduit having a valve 14. A
My invention is adapted to be used in connection with a plurality of evaporators as well as with the single evaporator described.
As shown in the drawings, the pipe 9 leading from the tank 5 may constitute a common inlet pipe for other evaporators 17 and 18 pO- sitioned in isolated cooling spaces 19 and 20 100 and providedI with valves 21 and 22l corresponding-to the valve 11 of the coil 10. The conduit 12 lis a common outlet or discharge pipe for all the condensers and'fojr the purpost of thermal eiiiciency, the pipe may surroundA the inletvpipe 9 throughout a portion of or substantially the entire length of the conduit 9.
The conduit 12 surrounding the conduit 9 terminates at intervals to permit connection of the coils with the pipe 9, the portions of the pipe 12 surrounding the pipe 9 being connected by conduits-12'. These connecting conduits can.v however, be omitted and the pipe l2 extend continuously along and around the pipe 9, the branch pipes to the coils in this ease being cast through the pipe l2 and into the pipe 9.
It Will be seen that the provision of the isolated separate tank 5 makes possible a material reduction in the size of the casing surrounding the coils. These casings While illustrated as being vertically disposed may' be arranged in any desired manner and positioned in separated locations.
Obviously those skilled in the art may make various Changes in the details and arrangement of part-s Without departing from the spirit and seope oi the invention as delined by the appended claims, and l therefore do not Wish to be restricted to the precis-e construction herein disclosed. v
Having tlruisl Jfully described an embodiment or" my invention, what l claim and desire to secure by Letters Patent of the United States is A l. In a refrigerating apparatus, an evaporator, a storage tank for condensed refrigerant thermally isolated from said Condenser, and a Conduit connecting said tank with said evaporator', said conduit being' extended upwardly `into said tank an appreciable distance to prevent the passage of Water through said conduit into said evaporator. y
2. In a refrigeratingapparatus, a boiler, an evaporator, a storage tank for condensed refrigerant thermally isolated from said condenser, an inlet conduit connecting said tank with said evaporator, and a drain conduit connecting said tank and boiler, the mouth of said inlet conduit being positioned above the bottom of said tank, thev mouth ot said drain eonduitbeing positioned adjacent the bottoni of said tank to, drain the Water from said tank'into said boiler,
3. ln a reirigerating apparatus, the eombi nation with an evaporator, of a boiler for receivingtherefrigeranttherefrom,connections between the evaporator` and boiler forming a circuit for conveying the refrigerant fromY between the boiler and evaporator for conveying the refrigerant from the boiler to the evaporator, said storage tankbeing thermally isolated from the evaporator, the first-named Circuit having` a portion adj aeent the evapor ator enclosed by the second-named Circuit.
4l. ln a refrigerating apparatus, the eenibination Oia plurality of evaporators having a common conveying means for feeding a refrigerant to each of the evaporator-s and a common conveying means for conveying the refrigerant away from the evaporators, the two conveying means for conveying the refrigerant to and away from the evaporators being connected in series to a boiler. a Condenser and a storage tank, the latter being thermally isolated from the evaporators, and said conveyingn means leading to the evaporators being enclosed by the Conveying means leading therefrom.
5. refrigerating apparatus comprising a boiler, a Condenser, and a storage tank arranged in series, with suitable conveying means for conveying a refrigerant from the boiler to the Condenser and from the condenser to the storage tank, al plurality of -evaporators adapted to be supplied with a refrigerant from said storage tank through a common Conduit leading from said storage tank to said evaporators, a plurality of means surrounding said eoanmon conduit having walls spaced therefrom to form a plurality of hollow chambers surrounding said conduit, means for connecting said hollow chambers in series to the boiler, and aeonduit from each evaporator connected to one of said hollovv Chambers. each evaporator being con-` nected to a different Chamber.
