Dependence of Air Temperature, Enclosing Structures and Floor in Livestock Premises

Abstract

The comfort of the animals is determined by temperature factors, such as air temperature, radiation temperature of the room and floor. For a reasonable technical decision on the choice of power equipment for creating normal conditions for keeping animals, it is necessary to identify possible variations in the temperature parameters of the environment in the animal housing zone. (Research purpose) The research purpose is in considering the models for calculating heat losses to the ground and determining the limit values for changes in floor temperature in areas where animals are housed. (Materials and methods) The article presents the studied physical model of heat transfer. The article presents the boundaries of changes in floor temperature in the areas of animal keeping in livestock premises. (Results and discussion) The thermal mode of a room depends on the climatic conditions that affect the state of the internal environment through the enclosing structures and ventilation, and technical factors, as the building structure, the size and thermal insulation properties of fences, heating. There are many types of designs of livestock premises for various purposes, and therefore it is necessary to conduct an additional assessment of the floor surface temperature. The engineering method of calculating the floor surface temperature determines the temperature in the room at known current values, and allows to predict the thermal state of the floor surfaces in the locations of animals. (Conclusions) Meteorological conditions and construction of buildings, thermal insulation properties of fences, thermal characteristics of the soil, floor insulation affect the temperature mode in the room. For buildings with lightweight structures of walls and ceilings, the surface temperature affects the thermal mode of floors in the room.
