Abstract
In a method and a device for cooling and carbonating a liquid (20), carbon dioxide intended for carbonating is also used for cooling, the carbon dioxide being brought to expand in a room (4; 7) which is separate from the liquid (20) but which is thermally connected to the liquid. By the invention it is achieved that an ice bank is formed in the liquid in the area which is adjacent to said expansion room (4; 7) whereby is achieved i.a. better cooling control than in previously known devices where the carbon dioxide also is used for cooling.
Claims18
A method for treating a liquid in a tank, comprising the step of:
- expanding carbon dioxide within a space which is separate from said liquid but which creates a thermal coupling with said liquid, said liquid being cooled by said thermal coupling.
A device for cooling and carbonating a liquid with carbon dioxide, comprising:
- a tank for containing a liquid to be cooled and carbonated, said tank having an inlet for carbon dioxide;
- and,
- a space for expanding carbon dioxide, separate from said liquid but thermally coupled to said liquid for cooling said liquid, said expanded carbon dioxide entering said tank through said inlet.
