What do you think are the possibilities to use energy from air scrubbers to provide pre conditioned air to the barns?
Heat recovery will become an important aspect in intensive livestock farming. Not only will we have to meet the ammonia, odour and dust reduction targets, but sustainability will also play a more crucial role in keeping livestock. At the moment, with heat recovery from the air scrubber, the farmer reuses the energy that the pigs produce to heat the stables, such as a heat pump or a Triple EEE system. Where the heat pump only serves to save energy, the Triple-EEE has many more advantages. With the Triple-EEE, the incoming air is preheated. This eliminates the cold peaks in the winter and actually brings a constant spring climate into the stable. This doesn’t just mean energy savings, but also improvements in feed conversion, mortality, healthy animals and optimal growth performance. On a typical pig breeding farm for instance, we see payback on equipment and running costs as soon as 4 years for the farmer. From then on, its free money in the pocket. Today I see only leading farmers adopt this approach, but in the future I expect over 70% of those rebuilding or upgrading their stables, will serious look at integrating this approach into their systems.
