Project Description


Background information and brief description of the project “EnergARA”:
Pig husbandry leads to emissions of ammonia, dust and odour, which can affect both local residents and nearby ecosystems. The use of exhaust air treatment systems serves to separate and reduce these emissions. In some German federal states, the use of these systems is required in the approval procedures for individual facilities. The keeping of pigs in closed houses requires energy, for example to operate the ventilation system or to maintain the room temperature according to the requirements of the animals. It is the task of the ventilation system to remove polluted stall air and replace it with fresh air. The use of heat recovery systems makes it possible to transfer energy from the warm exhaust air stream to the incoming cold fresh air stream and thus reduce the heating requirement in the barn.
In the "EnergARA" research project, three specific housing systems, which use an exhaust air purification system in combination with heat recovery, are to be investigated over longer periods of time. A recording of the power consumption of the individual systems as well as the air and water temperatures at different positions within the barn will be used to determine the efficiency and capacity of the heat transfer. The analysis of the collected data should lead to an economic, ecological and animal welfare based evaluation of the individual plants as well as their combined use. The aim is to identify possible synergy effects in order to answer the question to what extent exhaust air treatment systems can be used as regenerative energy sources for heating and cooling pig houses. Finally, the research project "EnergARA" should contribute to the improvement of energy and resource efficiency in modern pig farming.
