A cooler (1) is switchable between a first mode of operation in which a refrigeration circuit is controlled in response to thickness of an ice bank formed on an evaporator (9) of the refrigeration circuit so that complete erosion of the ice bank (13) can be prevented, and a second mode of operation in which the refrigeration circuit is controlled in response to temperature of the coolant (5) so that complete erosion of the ice bank (13) may occur. A compressor of the refrigeration circuit may be controlled in the first mode of operation to maintain a thickness of the ice bank (13) between upper and lower limits and in the second mode of operation to maintain the temperature of coolant (5) between upper and lower limits when the ice bank (13) has been completely eroded. |
