Heating performance of a laboratory pilot-plant combining heat exchanger and air scrubber for animal houses

Abstract Exhaust air treatment systems (EATS) are used in animal husbandry to reduce emissions. However, EATS are associated with high acquisition and operating costs. Therefore, a plant technology is being developed that integrates a recuperative heat exchanger into a biological air scrubber. The o...
