Abstract

We propose a method for creating optimum temperature microclimate modes at livestock facilities of different functional purpose by using a multi-layer heating floor. A structural mathematical model was constructed that makes it possible, under a preset operation mode of m-tiered tubular heaters, with respect to thermal conductivity of each layer of heat-generating modules, to define structural heat engineering parameters. We have obtained a general solution to the boundary value problem on determining the distribution of a steady temperature field in the multi-layered structure of MEHHS in the form of a prism with randomly arranged tubular heat sources.

The respective mathematical model of MEHHS that was developed solves the task on the optimization of formation of temperature parameters of the heating floor surface with an accuracy to 0.5‒1 °С. We have studied the model of automated MEHHS for effectiveness of resource-saving electrotechnology and for techniques for creating optimal thermal parameters of the heating floor surface in technologically-active zones (TAZ) at a livestock facility. It is proposed to substantiate parameters of MEHHS systems in terms of creating automated means to form the microclimate at PF in the agricultural sector that would enable structural-functional control over energy fluxes of power to STH of MEHHS under the mode consumer-regulator, which could ensure preset levels of temperature at the heating floor surface at livestock facilities of different functional purpose.
