Climate in pig houses

A diffuse air intake is a principle where the fresh air is lead to the room through the ceiling construction, taking the air from the attic. The air is coming through the insulation mat and cladding, and the air speed is thus reduced when having to penetrate this ceiling material. So, the idea with diffuse ventilation is to have a big open intake area, however with reduced airspeed in order to prevent draft, especially in cold periods. This principle is very suitable in relatively cold areas, but absolutely not to be recommended as the only option in areas with high summer temperatures.

In practice, it is important to choose the right type and amount of insulation mat as well as being careful to establish the correct amount of edge covering. This is essential in order to establish the correct amount of air as well as the correct negative pressure for the benefit of the animals. All these factors to be obtained in interaction with the amount of exhaust air, which is suitable for the animals in the section.

At SKIOLD we possess the experience and expertise in establishing a diffuse air intake. We have the knowhow using the necessary components as well as the composition in order to obtain the optimal diffuse air intake.

SKIOLD ventilation with wall or ceiling inlets has an optimal ratio between ventilation performance and energy consumption. The direction and speed of the airflow is adapted to the current conditions by controlling fan speed, chimney damper and valve opening independently of each other.

SKIOLD intake valves are available in PE (polyethylene) and PUR (polyurethane) and in several different sizes depending on the type of animal and area in the section. The intake valves are fitted with an insulated valve box and flap to prevent condensation and freezing.

In buildings with flat ceilings or insufficient volume, ceiling inlets are used. The ceiling vents are integrated into the ceiling cladding and the air is thus taken into the stable section via the ceiling space.

LA12

The LA12 servomotor controls the damper inside the chimney. The colored diodes on the outside of the LA12 control box is constantly giving a feedback from the monitoring and operating status. This is a real advantage at your daily operation check because you do not need to access the chimney but is having the full view from the diode indicators from distance.

The servo motor is positioning the damper within a span from 0 to 90° and is thus constantly optimizing the angle in accordance with the exhaust capacity. Further it contributes to maintaining a constant negative pressure inside the section, because it is compensating for the varying outside pressure onto the building.

LA35

The LA35 has the task of adjusting the opening level of the air intake, for instance the wall and ceiling inlets, thus having an essential impact on the optimization of the climate inside the section.

The servo motor has great reliability, long lifetime and a lot of smart functions, which contribute to a lot of useful information about the air intake. In the event of a power failure, the LA35 will automatically provide the optimal emergency setting of the air intake elements. This operation is secured via the built-in emergency power battery.

LA35 is the motorized unit which interlinks the complete ventilation system by coordinating the functions of the intake and the exhaust. The built-in potentiometer safeguards that the settings are absolute accurate. If inaccuracies are detected, the system will automatically carry out a test and adjust the system back to the correct position and setting. Also, the LA35 is equipped with color diodes, which are constantly indicating the operating status.
