2 Claims.

This invention' relates to the cooling of beverages by mechanical refrigeration. The invention contemplates the maintenance of predetermined temperatures yin a beverage dispensing system including a storage room and a beverage piping system extending from the storage room to a point of disposal. Both the storage room and the piping system are cooled by a single means located in the room wherein through the provision of a novel forced draft device, the piping system is maintained at an ,ideal dispensing temperature, while the room is maintained at the relatively higher temperature suitable for protective storage.

The invention will be found to provide a construction of extreme simplicity wherein auxiliary beverage cooling coils, as used in previous systems of this nature are eliminated, to the end that economies in initial cost and maintenance are effected. Several embodiments of the invention are described in the accompanying specication and drawings, wherein:

Fig. 1 is a diagrammatic cross section through a storage room and dispensing room, showing the forced draft conduit arrangement;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1, wherein a unit cooler is utilized in a differing conduit arrangement;

Fig. 4 is a section on the line @-4 of Fig. 3.

In the first embodiment of the invention (Fig. 1) an insulated storage room I0 is maintained at a constant low temperature by a refrigeration system (not shown) including cooling units I I which may be of the usual type having horizontal coils I2 and cross ns I3. The air in this room is circulated by convexion, the cooled air being directed to the floor where containers such as barrels ill are placed. The barrels contain bungs I5 which communicate with tubing sections IIi, I'l, I8, I9, 20 and 2I through iiexible tubing sections 22. Air under pressure is admitted to each barrel through a pipe 23 which connects each bung I5 to a source of pressure (not shown).

The tubing sections extend through the top wall of the room I0 and upward for connection with their respective taps Ilia IIa, etc., which are mounted on a bar 25 or other suitable dispensing fixture at a point remote from the room I0,

Inasmuch as the tubing sections between the room I0 and the taps would normally be'subjected to heat exchange with warm air, it has been found expedient to protect the tubing so that the beverage thereinmay be served at the desired y 55 temperature. The tubing sections exterior 0f the room iii, therefore, are enclosed in a common insulated conduit 26 which is concealed within the bar 25 and disposed conveniently close to the taps to facilitate connection therewith. In Fig. 2, for example, the upper extremity of the tubing section i6 is shown protruding through the conduit 26 for connection with the tap itc. The remaining sections are similarly connected to their respective taps.

The conduit 26 is devised with means for maintaining predetermined temperatures therein, both for protecting the beverage in the tubing sections during periods of disuse and for further lowering the temperature therein. Both ends of the conduit 26 communicate with the interior of the room iii, the tubing receiving end 2t of the conduit protruding through the ceiling of the room i0 and the remaining end E@ extending through a side wall of the room Ill, terminating in close proximity to one of the cooling units l i and being in axial alignment with the fins i3 thereof.

A forced draft circulation of cooled air is obtained in the conduit 26 by a' blower 3l which is located on the exterior of the room Ill and interposed in the conduit end 29. The blower 3! is operated by a motor 32 to withdraw air from the room I0 through a cooling unit ii and to direct the air stream in the conduit counter to the liquid flow in the tubing sections. The air exhausts from the conduit end 28 in a general downward direction.

Under practical operating conditions the room I0 is usually maintained at a 'low temperature, for example for beer storage, a temperature not greater than degrees Fahrenheit should be maintained to prevent spoilage. The refrigeration system by which the cooling units I I are A cooled is adjustable to control this condition by automatic means well known in the art. In systems of this nature the air leaving the cooling units is naturally 'lower in temperature than the average airv temperature maintained in the room, and this feature is advantageously utilized to maintain a lower temperature in the conduit 26 than is obtainable in the room I-Il. It has been found by drawing air directly through a cooling unit and into the conduit 26 that a temperature drop of approximately l0 degrees F. is obtainable in the conduit 26. Thus the room temperatures are maintained at a maximum by the cooling units II, and simultaneously the same cooling means is utilized to obtain the ideal and lower temperatures desired for serving the beverage.

In the embodiment of thelinvention shown in Figs, 3 and 4, similar cooling effects are obtained in a storage room 40 provided with a' well known type of forced draft unit cooler 4|. This cooler contains a core 42 which is connected in a refrigeration circuit and through which air is directed by a motor driven fan 43 for circulation in the room 40. Containers 44 are stored in the room and they communicate with tubing sections 45 and 48 which terminate exteriorly of the room 40 in taps 45a and 46a.

A conduit 41 is longitudinally bisected by a partition 48 (Fig. 4) to form input and output` manifolds 49 and 5I. 'The conduit 41 projects` into the room 40 and the terminal portion of its input manifold 49 receives a communicating air scoop 52, the mouth 53 thereof being disposed directly inthe path of the air stream from the core 42.

The tubing sections 45 and 45 extend through the wall of the air scoop 52 and are received within the input manifold 49. The upper end of the conduit 41 is capped by a cover 55 through which the extremities of the tubing sectionsi45 and 46 extend for connection to their taps 45a and 46a.

The partition 48 is spaced from the cover 55 so that the air stream entering the input mani--y fold 49 through the scoop 52 is directed around the upper end of the partition and downward through the output manifold 5| for return to the room 40.

In view of the higher air velocities' obtainable in the conduit arrangement of Fig. 1, its use is recommended in installations wherein the beverage circuit is complicated by extreme length or numerous connections. The device of Fig. 2 may be advantageously utilized in systems where the taps vare located but a short distance from the storage room. 5
