Abstract
An apparatus and method for cooling down milk in a milk cooling apparatus, where the milk cooling apparatus includes a coolant circuit with a milk cooling heat exchanger for heat exchange between milk and the coolant, and also includes a chiller with a refrigerant circuit for heat exchange between a refrigerant and the coolant, where the method includes measuring an OUT-temperature of the coolant upstream of the milk cooling heat exchanger and downstream a coolant cooling heat exchanger, and operating one or more compressors based on the measured OUT-temperature to minimize a difference between the measured OUT-temperature and a desired OUT-temperature, and also measuring an IN-temperature of the coolant upstream the coolant cooling heat exchanger and downstream the milk cooling heat exchanger, where the method configures how many compressors of the one or more compressors being active at a certain OUT-temperature based on the measured IN-temperature.
