Effect of Air Heat Pump Cooling System as a Greener Energy Source on the Air Quality, Housing Environment and Growth Performance in Pig House

The present study examined the cooling effects of an air heat pump (AHP) system. An AHP system was installed in a pig house to compare the effects with a traditional cooling system on the growth performance, noxious gas emission, housing environment and consumption of electricity. During the 19-week...

An AHP system was installed in a pig house to compare the effects with a traditional cooling system on the growth performance, noxious gas emission, housing environment and consumption of electricity. During the 19-week experimental trial, the internal temperature in the AHP cooling system-connected pig house was significantly decreased (<i>p</i> < 0.05) than the conventional house. Similarly, the temperature–humidity index (THI) was significantly reduced (<i>p</i> < 0.05) in the growing and late finishing period. The carbon dioxide (CO<sub>2</sub>) and electricity consumption were also reduced significantly in the AHP cooling system relative to the control. The concentration of ammonia (NH<sub>3</sub>) during the weaning and finishing phase and the concentration of hydrogen sulfide (H<sub>2</sub>S) during all periods were lower in the AHP-installed pig house (<i>p</i> < 0.05).
