- Abstract
Aiming at solving the problems of ventilation dead angle, unreasonable temperature distribution, and high energy consumption in traditional pigsty ventilation regulation. This paper proposes the use of semiconductor refrigeration technology to the pig's activity area of the local environmental regulation and then carries out the study. The air conditioning system based on semiconductor refrigeration was first constructed, and the working performance of the system was measured to obtain the optimal working conditions for the operation of the semiconductor refrigeration system. Then the pig house system was modeled according to the size of the pigs and the size of the restriction pens by SolidWorks software, and the distribution of the temperature field and air velocity field when the refrigeration system was applied to regulate the environment of the position of the pigs was analyzed by using ANSYS/Fluent. The results show that the system can make the ambient temperature around the pig maintained in the range of 22.86–26.93 ℃, the air wind speed is maintained in the range of 0.11–0.40 m s−1, at this time, the coefficient of performance (COP) of the refrigeration system is 1.13, which meets the environmental requirements of the healthy life of pigs. Finally, it is concluded that the application of semiconductor refrigeration technology to local environmental regulation in pig houses has good potential.
