The present invention provides a control system for controlling the ice volume fraction of a circulating ice-containing medium. The control system comprises a freezer apparatus for generating an ice-containing medium, a pump for circulating the ice-containing medium through a flow circuit comprising an outward line, a main line and a return line, and a bypass line connecting the outward line and return line to form a bypass circuit. In use, the time taken for circulating ice-containing medium to pass through the bypass circuit is less than the time taken for circulating ice-containing medium to pass through the flow circuit. The present invention also provides a method for controlling the ice volume fraction of a circulating ice-containing medium using such a control system. |
