Airconditioning of incoming air keeps houses cool
At the end of July the air conditioning once again proves to be a blessing for humans and animals. Even when it’s stiflingly hot outside, the livestock houses at the Van Dijk-Peters farm are still quite comfortable. The secret is conditioning of the incoming air, which is done using ‘Geo Balance’ technology from Inno+.
Coils of plastic pipe 42 kilometres long lie at a depth of four metres under the ground. Water is pumped through them continuously. At this depth the temperature is 12 °C all year round. The water in the LDPE pipe cools the incoming house air during the summer period. The air is conditioned by means of four heat exchangers, which are hung on the outer wall. There is one heat exchanger on each corner. Two heat exchangers maintain a constant temperature for the pregnant sows. The other two exchangers ensure a constant climate in the farrowing pens and service pen.
Twelve years’ experience with air conditioning in the houses
The company has twelve years of experience with this form of air conditioning. Van Dijk is still delighted with the technology in the houses “Air conditioning offers many small advantages that together make a big difference: Fewer dead sows. The birth weights of the piglets remain more constant throughout the year. The sows feed intake remains higher. The energy advantage: I burn less in the winter and ventilate less in the summer. All things considered, it was a good choice. I make a lot of decisions based on instinct anyway. That was the case here, and I still think it was the right decision.” Mark van Dijk.
