    • A device for generating an air wall comprises a primary blower slit for generating a flat primary air stream in a passage opening mutually separating two spaces with different temperatures. Two adjacent air streams with the same direction and speed are added to the primary air stream. The primary air stream has a temperature between those of the secondary air streams. The absolute humidity of the air of the primary air stream is at least equal to that of the cold secondary air stream and lower than that of the warm secondary air stream. The air speed of the primary air stream amounts to at least 15 m/s. The width of the primary blower slit lies in the range of 15-40 mm. The length of the primary blower slit in the direction of the air stream lies roughly in the range of 5-40 cm, preferably 10-30 cm. No mixing occurs hereby occurs between the primary air stream Sp and the second secondary air stream Ss2 on the side of the warm space, whereby condensation (misting and vaporization) and/or sublimation (icing) is prevented.
    • 一种用于产生空气壁的装置包括:主鼓风狭缝,用于在相互分离两个具有不同温度的空间的通道开口中产生平坦的一次空气流。 将相同方向和速度的两个相邻的空气流添加到主气流中。 一次空气流的温度与二次空气流的温度无关。 一次空气流的空气的绝对湿度至少等于冷二次气流的绝对湿度,并且低于暖二次气流的绝对湿度。 一次空气流的空气速度至少为15m / s。 一次鼓风机狭缝的宽度在15-40mm的范围内。 主风机狭缝在空气流方向上的长度大致在5-40厘米,优选10-30厘米的范围内。 因此,在温暖空间一侧的一次空气流Sp和第二次气流Ss2之间不发生混合,从而防止冷凝(雾化和汽化)和/或升华(结冰)。

    • The invention relates to a blower unit for generating an air wall for thermal separation of the air in a first relatively cold space from the air in a second relatively warm space, for instance the surrounding area, which spaces are mutually connected by a passage opening, the blower unit comprising: an elongate blower unit positioned on one side of the passage opening and comprising fan means and a blower slit for generating a flat air stream directed toward the opposite side of the passage opening. The unit has the special feature that the speed of the air in the air blower slit amounts to at least 15 m/s; the width of the blower slit lies in the range of 5-40 mm; the length of the blower slit in the direction of the air stream lies in the range of 5-100 cm; the cavity has a prismatic form; connecting to which cavity on one side is at least one air feed, extending substantially over the whole longitudinal dimension of the cavity, and on the other side the blower slit; in the upstream zone of which cavity an airflow resistance is present; and the zone of which cavity downstream of the airflow resistance has a form narrowing in the flow direction.
