Definitions
- This invention relates to drink coolers, and is concerned particularly although not exclusively with beer coolers.
- beer coolers are known. Generally, they may comprise a "product tank” having a coil through which beer passes, and which is immersed in coolant (usually chilled water) which is fed through the tank.
- coolant usually chilled water
- a problem that arises with known beer coolers of this type is to maintain the beer at a cold temperature up to the point of dispense.
- the beer it is customary for the beer to pass from the product tank to a dispensing tap via a "product line", which is typically a length of pipe.
- the product line may have some degree of insulation but, nevertheless, it is not uncommon for the temperature of the beer in the pipe to reach a higher temperature than is desirable, especially between extended periods of dispense, and this can give rise to "fobbing", which is the phenomenon of excess foaming (due to carbination) of beers such as lagers, stouts, etc.
- Preferred embodiments of the present invention aim to provide beer coolers which may be improved in this respect.
- a drink cooler comprising:
- a product tank having a first circuit for the circulation of a drink therethrough and a second circuit for the circulation of a coolant therethrough, so as to achieve heat-exchange between the drink and the coolant;
- a coolant line for carrying coolant from the product tank and passing the coolant alongside the product line so as to achieve heat-exchange between the drink in the product line and the coolant in the coolant line;
- the illustrated beer cooler 1 comprises a coolant tank 2 and two products tanks 3, which are substantially identical, and are disposed symmetrically at either side of the coolant tank 2.
- a layer of thermal insulation 4 is disposed between the coolant tank 2 and each of the products tanks 3.
- the product tank 2 contains a refrigerant coil 5, through which a refrigerant is passed in known manner, through an evaporator, pump and compressor unit, generally designated at 6. It is to be appreciated that all of the major components 2, 3, 6 are preferably mounted on a single base 7.
- the coolant tank 3 contains a coolant (typically water) which is circulated through the tank 3, in contact with the refrigerant coil 5.
- a coolant typically water
- Two coolant outlets 8 are disposed at opposite sides of the coolant tank 3, and lead each to a respective high capacity pump 9.
- a pair of coolant inlets 10 lead each to a respective vertical inlet tube, each of which is formed with a vertical series of holes from top to bottom, to direct coolant flow towards the adjacent walls of the coolant tank 3, as indicated in the figure by arrows.
- the coolant tank 3 is provided with a pair of secondary coolant inlets 12, each disposed adjacent a respective one of the inlet tubes 11.
- a thermostat 13 is placed within the coolant tank 2, within the path of circulating coolant flow, and detects the temperature of the circulating coolant.
- the compressor unit 6 responds to the output of the thermostat 13, to effect cooling via the refrigerant coil 5, when the temperature of the circulating coolant within the tank 3 falls between a predetermined temperature.
- Each of the product tanks 2 contains a product coil 14 having an inlet 15 and an outlet 16.
- a thermostat coil 17 is disposed around each product outlet 16.
- Each product tank 2 has a coolant inlet 18, a first coolant outlet 19, and a second coolant outlet 20. In use, coolant from the coolant tank 3 is circulated under pressure through each product tank 2 by means of the respective high capacity pump 9, and exhausted through the coolant outlets 19 and 20.
- a combined product/coolant pipe 21 is provided for each product tank 2.
- This pipe comprises concentric inner (product) and outer (coolant) pipes 23 and 24.
- the product pipe 23 is connected to a product outlet 16 on a respective product tank 2 and leads to a dispensing tap 22.
- the coolant pipe 24 is connected to the coolant outlet of that coolant tank 3. (Only one combined product/coolant pipe arrangement 21 is shown in the figure for convenience).
- the outer pipe 24 is connected to a coolant return line 25, which is connected to either one of the secondary coolant inlets 12 of the coolant tank 2.
- the illustrated beer cooler 1 operates generally as follows.
- a bulk container of beer e.g. lager, beer or stout under pressure
- a bulk container of beer e.g. lager, beer or stout under pressure
- the respective thermostat coil 17 detects whether the temperature of the beer at the product outlets 16 is sufficiently low. If the temperature is above a predetermined level, then the thermostat circuit causes the high capacity pump 9 to cut in, and this forces coolant through the product tank 2, where it undergoes heat-exchange with the product in the product coil 14, to cool the beer to the desired temperature.
- the coolant in the coolant tank 3 is maintained at its desired temperature, by means of the circuit which responds to the thermostat probe 13.
- the coolant tank 3 may contain a reservoir of ice built up within the refrigerant coil 5.
- the refrigerating capacity of the refrigerant circuit may be sufficiently great as to be capable of cooling the coolant water in the tank 3 to the desired low temperature, whatever the heat exchange demands of the two product tanks 2.
- Each of the coolant outlets 8 from the coolant tank 3 is of relatively large diameter and, preferably, each is provided with a U bend or non-return valve, to prevent unforced circulation of the coolant, when the pumps 9 are not activated.
- the coolant outlets 19 and 20 from the product tanks 2 are of smaller diameter than the coolant outlet 8 from the coolant tank 3, so as to maintain the coolant in the product tanks 2 under pressure. It will be appreciated that, in addition to circulating the coolant through the product tanks 2 and directly back into the coolant tank 3 via the coolant outlets 19, a further flow of coolant is caused through the outer tube 23 of each product line 21, and back again through the respective return line 25.
- the cross-sectional area of the return line 25 is smaller than that of the outer pipe 23, so as to maintain the coolant under pressure.
- the illustrated beer cooler may be improved over known beer coolers in a number of ways. Firstly, the provision of the secondary coolant flow within the product line 21 may ensure that the beer is kept at a satisfactorily low temperature, virtually all of the way to the dispensing tap 22, irrespective of the intervals between dispensing operations. Secondly, the positioning of the thermostat coil 17 at the product outlet 16 ensures that the high capacity pump 9 cuts in only when the product temperature rises. (If desired, alternative or additional thermostat coils may be provided further along the product line 21. As another alternative, the thermostat coil 17 may be disposed at the product inlet 15). It is to be noted that, as shown in the diagram, the thermostat coil 17 is partly within and partly outside the respect product tank 2.
- a further advantage of the system is that two product tanks 2 may be conveniently located either side of a common coolant tank 3, with thermal insulation 4 therebetween, to minimize unwanted heat transfer.
- the product line 21 is provided with push on pipe connectors, for easy connection of the product line 21 to the product outlet 16, coolant outlet 20 and coolant inlet 12.
- suitable thermal insulation is provided around the coolant pipes 23, 25.

Abstract
Un refroidisseur (1) de boissons comprend un réservoir (3) de liquide de refroidissement et un réservoir (2) de boissons. Le réservoir de liquide de refroidissement (3) envoie du liquide de refroidissement à travers le réservoir de boissons (2) afin de refroidir celles-ci. Un tuyau de boissons/liquide de refroidissement combiné (21) comprend un tuyau central (23) en communication avec le réservoir de boissons, et un conduit de liquide de refroidissement (24) en communication avec le réservoir de liquide de refroidissement (2). Les boissons contenues dans le tuyau de boissons/liquide de refroidissement (21) sont maintenues à la température voulue grâce à l'échange de chaleur entre les boissons et le liquide de refroididssement. Les boissons refroidies sortent par un robinet (22). En maintenant froides les boissons jusqu'au point de distribution, on peut les empêcher de mousser et on peut les servir à une température plus basse et plus rapidement qu'avec des appareils connus.
