Abstract
A cooling and carbonation apparatus (1) is described which has a cell (2) through which fluid to be cooled and carbonated flows. The cell (2) has first and second sidewalls (9, 15), and an outer wall (13) at least partially enclosing the first sidewall (9) of the cell (2) to form a coolant chamber on a first side of the cell. A cooling device (21), such as a Peltier device, is disposed on one side of the cell (2) in thermal connection with the cell (2), so that heat can be withdrawn from the coolant and the fluid to be cooled in a direction generally across the flow path of the fluid. A body of refrigerated coolant is maintained adjacent to the first sidewall (9) of the cell (2) thereby enhancing the cooling of the fluid. Carbon dioxide can be fed to the cell (2) and the liquid to be cooled pumped out of and back to the cell (2) to improve carbonation.
