However, in the case of a plant or ship installed on the land or sea in a low temperature region, since the temperature of the outside air is too low, icing or icing phenomenon occurs in the inside of the outflow window.

Fig. 1 shows a heat ray structure arranged in a wind-up window as a conventional plant or ship wintering system.

As shown in the drawings, in the conventional case, a heat ray 5 is provided through a ventilation window 3 provided in a plant or a ship 1, and the heat ray 5 has a height H direction of the ventilation window 3, (D) at a constant interval. And a control unit 7 for controlling the heating operation of the heating wire 5.

However, when ice is icing through a ventilation window of a plant or a ship installed on a land or a sea in a low temperature region, ice is not evenly iced on the entire surface of the vane plate arranged vertically to the ventilation window, It can be seen that a large amount of icing phenomenon appears at the center portion than at both end portions. This is due to the fact that the air suction pressure is relatively strong at the height of the wind tunnel or in the longitudinal center portion.
