Conception d’un système de chauffage à condensation pour le domaine agroalimentaire nord Américain

Abstract : In Canada, the energy expenses for the poultry production has seen a recent rise due to the increase in energy cost to assure the infrastructure heating of the indoor breeder house. Improvement in the energy efficiency and maintenance of non-humidified environmental the breeding house can considerably reduce the energy expenses and preserve the health of the poultry animals and in turn yield an increase in the productivity. The principal objective of this study is to design a numerical model to simulate the air properties in the heating circuit inside the poultry breeding house. A literature review of the norms and regulations of poultry breeding was carried out to understand the optimal conditions that satisfy a good and healthy poultry production. The calculations for heat balance were performed based on heat exchanger and hot air furnace that give the physical properties of the circulating smoke and air in the heating appliances. To reduce the heating expenses, we have recovered a quantity of heat energy from the exhaust air to preheat and dehumidify the exterior in coming air with the help of a heat exchanger. The exterior air is relatively 90% humid and at a temperature of -10°C. The heat exchanger is an air-air type exchanger with 33% efficiency, created by the “Énergie Solutions Air”. The heat exchange between exhaust air which is at 20°C raises the temperature of the exterior incoming air to 0°C and reduces the incoming air humidity to 38.27%. To improve this heat exchange and increase the preheating temperature, we will use a quantity of the nonrecoverable heat released by the combustion of the smoke, released by the heat furnace which is at 80% efficiency. We show that the recovered 24.03% of the non-recoverable heat increases the temperature of incoming air that enters the heat exchanger ESA to 126.36°C, provided we combust an excess air of 40%. But the stoichiometric combustion calculation will recover only 18.82% to arrive at the same temperature of 126.36°C.
