• Description:
  The objective of this study is to develop a simulation model of a ventilation system for a modern swine confinement. The confinement is divided into two zones: the room where the pigs reside and the pit that stores the waste. Two fans located in the side wall of the room and one fan located in the end wall of the pit are used to control the indoor air quality (IAQ) within the confinement. IAQ in this study addresses thermal and pollutant factors. For each zone, the conservation of mass and energy equations are written. The conservation of mass equations apply for dust, ammonia, and water vapor concentration. The conservation of energy describes the air temperature of the zones. The equations contain heat generation terms for thermal energy due to lights, heaters, and pigs, and mass source terms due to dust, water vapor, and ammonia. Relations for the generation terms are presented. An icon-based software is used to solve the system of equations that represent the IAQ models. Results of temperature, humidity, and concentrations of ammonia and dust are obtained from the simulation model under different conditions. By successfully examining the example cases, further investigations are warranted on larger-scale models having more complexity, components, control algorithms, and applications.
