Abstract
BACKGROUND: The rational application of thermal energy storages with phase transition for objects of the food industry with significantly uneven heat loads is discussed in this article. The drawbacks of existing ice banks, suppressing their spread, are analyzed. Possible methods of addressing these problems during the designing process are considered.
AIM: Development of a new generation of ice banks with a high intensity of ice melting processes and the ability to adjust the heat load.
MATERIALS AND METHODS: The brand-new discharge method based on the film flow around ice surfaces is proposed. The proposed approach allows us to optimize the heat load and provide the maintenance of the required ice water temperature. The laboratory sample of the coaxial film heat exchanger (FHE) was designed by the authors.
RESULTS: Experimental results in the operating range of the levels of supplied water temperatures 20 ℃, 40 ℃, and 60 ℃ and mass flow rates 15, 30, 45, and 60 kg/min are carried out. The experimental results confirmed that the development construction of the FHE with the film mechanism of the heat transfer provides increasing efficiency in orders of magnitude in comparison with ice banks with bulk melting. The reduced heat load with a mass flow rate of 60 kg/min and medium temperature on 60 ℃ was 220–240 kW/m2, and the maximal reduced heat load of the upper layer of coil reached 1300 kW/m2. The generalization of the results showed the application prospects of film ice banks in the refrigeration systems of various industrial and agricultural objects.
