Models and algorithms for regulating microclimate parameters in storage facilities of agricultural products
Annotatsiya
The paper presents an algorithm for the developed mathematical model of heat and mass transfer processes in storage rooms for perishable agricultural products; the algorithm makes it possible to determine the operating modes of the heat pump regulator. It was established that in the bulk accumulation of vegetable products the boundary of the area with a linear law of resistance expands to values Re3=400 . 625 and higher. It is also known that local losses prevail in dense layers, which excludes the formation of microvorticity, and the use of two-dimensional flows in the area of motion excludes macrovorticity. When developing the automatic control system of heat supply processes, it was taken into account that the dynamics of thermal processes occurring in heat exchangers is determined by a large number of parameters related to the design of the apparatus, the conditions of heat exchange on the surfaces of products, the temperature of the media exchanging heat, and the flow rate of the coolant.
