High electricity consumption, carbon dioxide (CO2), and elevated noxious gas emission in the global livestock sector have a negative influence on environmental sustainability. This study examined the effects of a heating system using an air heat pump (AHP) on the energy saving, housing environment, and productivity traits of pigs.

During the experimental period of 16 weeks, the internal temperature was found to be higher in the AHP house than in the conventional house. Moreover, the average electricity consumption and CO2 emission decreased by approximately 40 kWh and 19.32 kg, respectively, in the AHP house compared to the house with the conventional heating system. The average NH3 and H2S emissions were significantly lower in the AHP house during the growth stages. The AHP and conventional heating systems did not have a significant influence on the average ultra-fine dust (PM2.5) and formaldehyde level fluctuations. Furthermore, both heating systems did not show a significant difference in the average growth performance of pigs, but the weight gain tended to increase in the AHP house.

In conclusion, the AHP system has great potential to reduce energy consumption, greenhouse gas (GHG) emissions, and noxious gas emissions by providing economic benefits and an eco-friendly renewable energy source.
