Experimental study of radiation cooling for milk coolers

This paper presents the results of an experimental study conducted at a milk-cooling installation using effective radiation of the Earth. The results of the experiment showed that in the initial period the temperature of the surface of the radiator is cooled below ambient temperature by 2°C. After turning on the pump and pumping the coolant through the radiator, the surface temperature of the radiator rises on average by 3°C above atmospheric air. In the morning, the temperature of the atmospheric air and, accordingly, the radiator rises and the process of cooling water in the cold accumulator ends. From the results taken, it follows that the radiator with night-time radiation cooling is operational and the water from the cold accumulator is cooled to a temperature closer to atmospheric air.
