Adiabatic cooling system in pigsty

At a pig farm in Kortemark, the air inlet was equipped with an evaporative cooler in which the incoming air is humidified.  Thus the temperature will drop and the humidity will increase.  Both in the fattening pigs and in sow stalls it is necessary to ensure that the temperature in the barn does not rise too high during the summer period.  The target temperature of 19°C for fattening pigs and lower than 21°C for a sow is often not feasible.  At stable temperatures above 30°C, a pig takes up even less feed.  A higher temperature can have negative consequences for the next litter.  The units were mounted in the side wall and provided with a plastic package to make the exchange between air and water as large as possible.  A water buffer was provided near the stable.  A pump that is controlled from the climate computer will pump water from the rainwater buffer to the various evaporative coolers.  Part of the water will evaporate.  The surplus part runs back to the buffer tank by gravity.
