What is good today must be better tomorrow…
That is the philosophy behind the Vevar pig farm run by the van der Velden family. It is a modern pig farm with locations in the Netherlands and Germany. It is their passion to be and remain a leader in every field, a line of thinking that Inno+ asked us to help realise in the realisation of the new piglet house.
The existing house is already equipped with a Triple EEE system and heat pump. The latter is already dimensioned for the newly built piglet house and a future house. This will ensure that all three stables have the most sustainable housekeeping possible. A large part of the energy requirements of this system is provided. Apart from making the entire concept more sustainable, this is also particularly advantageous given the current gas and electricity prices.
A step forward
A total of 6,500 piglets are kept in the newly built barn. To take the next step towards a more sustainable piglet farm, it was decided to pre-condition the incoming air. The heat that is used is released from the section and goes to the central exhaust channel via the individual exhaust channel.
At the end of the central drain, two air scrubbers are installed, each with a capacity of 78,000 m3 air per hour. These biological scrubbers are constructed in accordance with BWL 2010.02.V6 and have a minimum ammonia reduction of 85%. During the washing process, the heat from the stall air is captured in the process water. This process water is the source of heat for the pre-conditioning of the stables.
The heated process water and the process water from the existing stable are fed into a central process water tank. This is where the parameters and operation of both scrubbers are centrally controlled and logged. But this is also the place where the heat is extracted by means of our Triple EEE system. By means of a separate system, the heat is transferred to the secondary circuit and pumped towards the inlet exchangers.
At the front of the house, there are four inlet exchangers, each with a capacity of 120 kW. With this installed capacity, it is even possible to pre-condition at -10° Celsius outside air temperatures. The heat enters the department through the perforated ceiling.
Always guaranteed temperature
The size of the process water well was designed from the start to accommodate more than just one Triple EEE system. The existing barn already has one Triple EEE system with inlet exchangers and one Carrier heat pump. The heat pump is not part of the pre-conditioning but gets its maximum output by heating the floor heating in the wards.
Past, present, future
Together with excellent operational management and the preconditioned air, this ensures that the use of antibiotics is minimal. Due to the reduction of the air scrubbers, the odour is limited for the neighbourhood. Together with Inno+ and its systems, there will be a further reduction of ammonia, waste, antibiotics, and energy.
Where in the past extra heating was used, it is now pre-conditioned and optimised with the underfloor heating. The future… It smiles at us.
