Case study no. 7:
Stable ventilation in animal husbandry
Initial situation
Stables in animal husbandry are forced ventilated, resulting in low temperatures in winter and very high temperatures in summer. In summer in particular, very high temperatures can occur in the barn, as the animals themselves give off a lot of heat.
This temperature range means a high risk of disease for the animals and increases the need for medication to contain or prevent the risk of disease.
Technical heating or cooling of the incoming fresh air by means of heating or air conditioning would mean an enormously high energy requirement, as the barn buildings in modern animal husbandry are very large.
Task definition
The stable building is to be preheated in winter and precooled in summer by means of a basic feed into the supply air heat exchanger. The heat exchanger must be resistant to the contaminated and therefore corrosive air in order to ensure high availability and perfect hygiene.
Solution
The Calorplast gas-liquid heat exchanger made of polyethylene (PE) is made entirely of corrosion-resistant material.
Thanks to its modular design, it can be installed as a large-area solution in the side walls of the barn, whereby the heat exchanger design in the large inlet openings and as a heat exchanger for the intake between the foundation structure and the sheet pile wall have proven their worth.
Result
The groundwater has a largely constant temperature of 10-15°C throughout the year.
In winter operation, the outside air can be preheated and, together with the energy output of the animals, this results in a consistently pleasant temperature. In summer operation, the groundwater cools the outdoor air, which is clearly too warm, down to pleasant temperatures and thus ensures the well-being of the animals.
