Climate change: Earth-air heat exchanger best to protect animals in livestock buildings

(University of Veterinary Medicine -- Vienna) Without countermeasures, climate change will negatively impact animals in pig and poultry production. Beside health and wellbeing of the animals, heat stress also affects performance and thus profitability. Now, researchers at Vetmeduni Vienna examined the inlet air temperature of several air cooling systems. The best solution is the use of the earth for heat storage via an earth-air heat exchanger (EAHE). An EAHE cools in the summer, and warms up th...
