The intensive development of pig farming has led to the emergence of new ventilation methods on modern farms that utilize minimal energy resources. Technologists strive to consider all factors that affect animal productivity and reduce the impact of critical temperatures on animal well-being. In hot weather, highly efficient evaporative cooling systems such as PadCooling and nozzle systems are actively used. They are being installed not only in southern regions but also in central regions, Siberia, and the Urals. In cold regions, heat recovery systems are being actively implemented, significantly reducing energy consumption for heating the facilities.

One of the most interesting new ventilation methods is the use of a system that preheats the air in a corridor and subsequently delivers it to the overhead space of the farm. The prepared air then enters the pig-rearing area through ceiling air inlets, can be additionally heated if necessary, and removed using adjustable exhaust chimneys. This system can be adjusted to provide the desired air flow rate, which is not always achievable with side air inlets due to wind interference.

This scheme combines the advantages of a ventilation system based on the negative pressure principle using supply air inlets and a system that delivers air through the roof, with the air reaching the animals already warmed.

The presence of a corridor and overhead space also allows for proper air cooling during the summer period. The cooled supply air will not create drafts in the animal-rearing area. After passing through cooling cassettes, the fresh air first enters the roof area from the corridor and then, due to negative pressure, it flows through the ceiling air inlets into the pig section. At the same time, the degree of opening of the air inlets and the performance of shaft fans can reach maximum values.
