Abstract
A beverage dispensing system has a water line to be connected to a source of water, a refrigeration evaporator line extending through and along a length of the water line, and a thermostatic control that has a sensing element extending along refrigerated portions of the water line.
Claims14
A refrigeration system for first and second sources of beverage ingredient, comprising:
- a. a condensor;
- b. a refrigeration compressor having a discharge connection to said condensor;
- c. a first evaporator adapted to be in heat exchange relationship with the first source of beverage ingredient;
- d. a second evaporator adapted to be in heat exchange relationship with the second source of beverage ingredient;
- e. a refrigeration line, including a first capillary tube, connected at its upstream end to said condensor;
- f. a valve interconnecting the downstream end of said line to said first evaporator;
- g. a further refrigeration line, including a second capillary tube, interconnecting said downstream end of said first-named line to said second evaporator;
- h. an accumulator;
- i. a first suction line from said first evaporator and a second suction line from said second evaporator, both of said suction lines being connected to said accumulator, and a further suction line from said accumulator to said compressor;
- and
- j. thermostatic control means adapted to sense the temperature of beverage ingredient in the first source, and connected to actuate said valve and said compressor.

A beverage mixing and dispensing system, comprising:
- a. a water line for being connected at one end to a pressurized source of water, its other end leading to an outlet;
- b. a refrigeration system having an evaporator line extending through and along a length of said water line;
- c. a thermostatic control for said refrigeration system having a sensing element extending along refrigerated portions of said water line;
- d. a source of liquid flavored beverage ingredient;
- e. a second evaporator line connected in parallel with said first-named evaporator line and disposed to refrigerate said source of beverage ingredient;
- f. a second thermostatic control for said refrigeration system responsive to the temperature of said source of beverage ingredient;
- and
- g. a valve in said first-named evaporator line under the control of said first-named thermostatic control.
5 more elements
A beverage dispensing system which includes a supply of water, said supply comprising:
- a. a water line a length of which is arranged as a helical coil for being connected at one end to a pressurized source of water, its other end leading to an outlet;
- b. a refrigeration system having an evaporator line arranged as a helical coil extending through and along said length of said water line and thus surrounded therby;
- and
- c. a thermostatic control for said refrigeration system having a sensing element being arranged in a zig zag manner and extending along refrigerated portions of said water line in engagement with successive adjacent pairs of turns of the water coil, said sensing element having a longer portion engaging the outlet end of said water coil which is shorter than the portion engaging the inlet end.
