Abstract


Pigsty heating is very important in the hog production environment engineering and technical measures to ensure the health and normal growth and development of the pigs has important significance . The pig is just a near- ground regional activities animals to lie down in a long time . Floor heating , even in the case of low indoor temperature compared with conventional air heating , can still make the pig lying down area to maintain a a relatively suitable temperature conditions and the local environment of the dry sanitation , is conducive to the growth and development and production of pig performance of the play . Form of underfloor heating heating in northern China in pig production , although some applications , but the system is still a lack of pig heated floor heat transfer mechanism , the influence of various parameters on the thermal performance , and how to determine the floor structure parameters theoretical studies , affected piggery floor heating effect and operation of energy conservation and economy . This paper summarizes a the pig floor heating the heat transfer process related factors , the analysis of the relationship between the amount of heat the floor structure of the low temperature hot water floor surface and floor heat transfer medium temperature , contact with the floor of the heat transfer of pigs lying mechanism . On this basis , a mathematical model of heat transfer process of the pig lying low temperature hot water floor . Using ANSYS software , the ground floor within a certain range of different geometry , boundary conditions , heat the numerical simulation , and the simulation results obtained made ??in the appropriate form . According to the relationship between the numerical simulation results and the influencing factors and the amount of ground heat obtained mainly for heating tube spacing and depth of floor heating material must ensure that the structural parameters of the surface temperature uniformity , and its optimized and the preliminary experimental validation of the floor heating in the economy , construction Note also given preliminary study , economic operation and construction design of the pig floor heating system has certain reference value .
