Definitions

  • the present invention relates to beverage chillers.
  • TEMPRITE Another known beverage chiller is a product known as TEMPRITE.
  • the beverage passes through a single spiral coil that is immersed in refrigerant.
  • this product uses a float in conjunction with a cartridge valve.
  • a shortcoming with this equipment is that it requires frequent ongoing maintenance with the ensuing cost associated with servicing.
  • the float and cartridge valve control utilised in the product is prone to sticking in an open position or leaking after a period of use. If such conditions are left unchecked, flooding of the refrigerant into the compressor can occur and can lead to compressor failure.
  • a beverage chiller comprising at least two interconnected canisters, each canister defining a chamber for refrigerant, said chamber including a plurality of pipes extending along the length of the chamber for the flow of beverage therethrough, each canister including flow control means to ensure flow of beverage up and down the refrigerant chamber in a plurality of cooling passes, said refrigerant chambers being pressure balanced and arranged to be coupled to a source of refrigeration via a thermostatic expansion valve.
  • the canisters are interconnected such that the beverage completes its cooling passes in one canister before completing further cooling passes in the second canister.
  • a flow control means is provided at each end of each canister to ensure flow of beverage up and down the refrigerant chamber in a plurality of cooling passes. It is further preferable that the flow control means comprises a partitioned plate provided at each end of each canister.
  • each of the chambers is coupled to a source of refrigerant and an evaporator pressure regulator valve.
  • the refrigerant chambers of the canisters are interconnected at three points along the length of the canister where a first connection is a suction connection that is in turn coupled to a compressor of a refrigeration circuit, a second connection is a balancing pipe that ensures pressure balance between said canisters, and a third connection is a thermal expansion valve feed connection.
  • the pipes of each chamber are arranged in an array which is parallel to the principal axis of the canister.
  • Figure 1 is a side elevation view of a preferred embodiment of a beverage chiller according to the present invention
  • Figure 2 is a plan view of the beverage chiller depicted in Figure 1 ;
  • Figures 3 and 4 are plan views of upper and lower directional flow plates utilised in the preferred embodiment of the beverage chiller.
  • Each canister 11 , 12 preferably houses thirty two stainless steel pipes 20 of relatively small bore that are arranged in an array which is parallel to the principal axis of the canister.
  • the pipes 20 are of 4.8 millimetres (3/16 inch) nominal bore and approximately 300 millimetres ⁇ - 12 inches) in length and are supported at either end by directional flow plates 21, 22.
  • the directional flow plates 21 , 22 are provided with thirty two small holes 23 and the ends of the pipes 20 are welded into these holes.
  • the upper flow plate 21 has its upper surface 26 segmented into five compartments 30, 31 , 32, 33, 34 by upwardly projecting and radially extending baffles 27.
  • the lower plate 22 has its lower surface 28 segmented into four compartments 35, 36, 37, 38 by radially extending baffles 29.
  • the canisters are closed and sealed at both ends 40, 41.
  • the cavities 50 that house the pipes 20 between the directional flow plates 21, 22 of the canisters contain refrigerant and are coupled to a standard refrigeration circuit which includes a source of refrigerant and an evaporator pressure regulator valve. It is understood that the design and operation of the refrigeration circuit would be well known to those skilled in this art and therefore it is not described in detail in this specification.
  • the refrigerant cavities 50 of canisters 11, 12 are interconnected at three points 53, 54, 56 along the length of the canisters.
  • the upper connection 53 is a suction connection that is in turn coupled to the compressor of the refrigeration circuit.
  • the central connection 54 is a balancing pipe that ensures pressure and refrigerant level balance between the canisters 11 , 12.
  • the lower connection 56 is a T.X. (Thermostatic Expansion) valve feed connection.
  • the T.X. valve temperature control is located at a point approximately 300 millimetres (» 12 inches) along on the upper connection 53 on the suction pipe to the compressor.
  • the end segments 43, 44 are welded against the adjacent outer edges of the baffles 27, 29 to define segmented compartments 30 to 34 and 35 to 38 at each end of the canisters 11, 12.
  • one compartment 30 at the top of each canister has an opening which constitutes the beverage inlet 61 and beverage outlet 62.
  • the compartments 34 are interconnected by a bridge 65.
  • the beverage to be chilled enters the first canister 11 via the inlet 61 into compartment 30.
  • the beverage then flows down the four small bore pipes 20 contained in segment 30 to reach the compartment 35 defined by the lower directional flow plate 22.
  • the beverage then flows up the four pipes to reach the upper compartment 31. It then flows down four pipes to reach compartment 36, back up to compartment 32, down to compartment 37, up to compartment 33, down to compartment 38 until it reaches upper compartment 34 from where it proceeds to the second canister 12 via bridge 65 where the circulation operation is repeated.
  • the beverage chiller As the beverage passes through the chiller in each canister, it is passed through four single pipes concurrently and then returns to a separate set of four pipes that are all identical in size. Consequently, the beverage is passed through eight sets of four pipes in each canister.
  • This lengthy and convoluted route for the beverage to pass is contained within the source of refrigerant which means that there is an enormous opportunity for heat exchange between the refrigerant and the beverage. Consequently, the beverage chiller has the capacity to chill beverages to the desired temperatures of 2 to 3°C whilst providing a flow rate of 50 litres an hour.
  • the design of the beverage chiller provides a heat exchanger of high efficiency which allows the performance criteria to be reached with a very compact unit that is very efficient in the use of power.
  • This system is designed to operate on a variety of refrigerants and especially 134A or R12.
  • Each canister is mounted with its axis vertical and filled to 75% of full capacity with refrigerant.
  • the T.X. valve controls throughput of refrigerant whilst at the same time acting as a level control.
  • a T.X. valve is a simpler and more efficient means of controlling refrigerant levels than the complicated float valve that is currently used.
  • the beverage chiller can be incorporated into a refrigeration circuit or could be simply coupled to an existing refrigeration system.

Abstract

Cette invention a trait à un dispositif réfrigérant amélioré pour boissons (10) comportant au moins deux caissons interconnectés (11, 12), délimitant chacun une enceinte (50) pour frigorigène, cette enceinte comprenant plusieurs tuyaux (20) déployés sur toute sa longueur et destinés à assurer l'écoulement de la boisson. Chaque caisson est pourvu de mécanismes de commande du débit afin de faire monter et descendre la boisson à l'intérieur de l'enceinte réfrigérante par plusieurs conduits de refroidissement. Ces enceintes réfrigérantes, qui sont à pression régulée, sont agencées de manière à être raccordées à une source cryogénique via un détendeur thermostatique (56).
