Abstract

PURPOSE: To eliminate drawbacks of a variable pitch fan by providing a vacuum fan heat exchanger being employed in a ventilator for cowhouse with two blades for discharging excess heat in summer season and removing excess moisture in winter season by reversing the rotation of a fan. CONSTITUTION: Control shaft 12 of a reversible blade 13 is provided at the lower end thereof and the end part is substantially aligned with the diameter. These blades 13 produce an upward or outward air flow constantly in a passage 4 regardless of the rotational direction of a motor 10. Since a blade 14 is fixed, air flow is reversed in the passage 3 when the rotational direction of the motor 10 or a fan 1 is reversed. The fan 1 is changed from a vacuum tan to a heat exchanger by simply reversing the rotational direction through the motor 10 and the air flow is directed inward in the passage 4.

DETAILED DESCRIPTION OF THE INVENTION There is a need, especially in cattle barns, for ventilation systems that can remove excess heat during the warm season and excess moisture during the cold season.

Excess heat is conveniently removed by means of a vacuum fan, since large volumes of air can be transferred with minimal power consumption. To reduce humidity, heat exchangers can be used as described below. That is, the cold intake air is warmed by the moist exhaust air. The ventilation requirements are therefore too low to allow the use of the lower efficiency vacuum fans. On the other hand, in southern and central Finland, sufficient heating is obtained if the air drawn in is heated to an extent corresponding to one quarter of the temperature difference between indoor and outdoor air. For example, if the temperature difference is 40°C, heating at 10°C is sufficient.

In the ventilation of cowsheds, it is known to use fans with radially two-part propeller blades operating in the inner and outer aisles. Furthermore, the pitch of the propeller blades can be varied independently of each other in the inner and outer passages.

The ventilation effect of this type of fan is adjusted by changing the pitch of the propeller blades. However, the adjustment mechanism is rather complex and expensive. It is fairly easy to adjust the pitch of the propeller blades by changing the voltage while keeping the pitch constant. Furthermore, if the pitch of the propeller blades could be reversed to cause the airflow to flow in the opposite direction, such a device could be used as a heat exchanger. However, in the case of adjustable pitch,
The system that regulates the hitch is extremely complex.

The control shaft 12 of the reversible blade 13 is provided at the lower end of the blade 13, which end is aligned with the radius. These blades thus always produce an air flow in the passage 4 from bottom to top or from the inside to the outside, regardless of the direction of rotation of the motor 10. Since the blade 14 is fixed,
When the direction of rotation of the motor 10 or the fan is reversed, the direction of airflow is reversed within the passageway 3. Thus, the fan according to the present invention can be replaced with a vacuum fan as shown in FIG. 1 by simply reversing the direction of rotation of the motor 10 or the fan.
It changes into a heat exchanger as shown in the figure.

If it is desired to keep the flow direction of the outer passage constant, from inside to outside, the reversible blades are mounted on the outside of the intermediate frame and the fixed blades on the inside of this frame. When the direction of rotation of the motor 10 is changed, the vacuum fan device operates according to the principle shown in FIG. The airflow in the passageway 4 is directed from the outside to the inside in FIG. 2, and the airflow in the passageway 4 is directed from the outside to the inside.
