DYNAMICS OF TEMPERATURE REGIME OF LIVES YOUNG DAIRY ANIMALS WITH LOCAL ELECTRICITY OF MATHEMATICAL MODEL
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 6
Abstract
The article deals with the theoretical analysis of thermal processes of premises for keeping animals, which are equipped with systems of local heating of young animals. Assumptions have been made to analyze heat processes in animal housing, which considerably simplify the simulation procedure: the room is considered as an object with lumped parameters; air indoors perfectly moves; the heat transfer coefficients in time do not change and are equal to the mean values during the transition process. In connection with the presence in the premises of different capacities that can accumulate thermal energy, when compiling differential equations for each of them a separate thermal balance is formed. Taking into account the assumptions made and the adopted scheme of the process, the equation of thermal balance for the following capacities is made: air, external fence, electric heater mat, emitter. Applying the Laplace transform for the received linearized system of equations, taking into account assumptions and zero initial conditions, an "Input-Output" equation for the main thermal capacities of the object was obtained and a structured scheme is presented that represents a linear model of the dynamics of the thermal regime of the system of local heating of young animals and the thermal regime premises of the pig-breeder under the influence of controlling and disturbing factors.
