This study is based on experimental data obtained on the milk cooling system at the training cattle farm of the State Agrarian University of Moldova, which comprises both natural and artificial sources of cold: a refrigeration unit and a natural cooling installation. The paper describes the structure diagram and operating principles of the natural and artificial cold receiver/accumulator with low energy consumption. The control parameters of the milk cooling process in the flow-through cooler by using natural and artificial cold were selected: water temperature in the accumulator installed outside the farm, water temperature in the accumulator installed inside the farm, atmospheric air temperature, and temperature of cooled milk. The operating algorithms for the receiver/accumulator under study are presented based on automatic graphs and logical algebra. The specific energy consumption for milk cooling when using the proposed installation is 0.3 kW h/t in the cold season.
