1. Ji'nan ventilation pipe processing strip seam air supply through the strip shaped air supply air supply, its range is short. The temperature difference and the speed change are fast, and it is suitable for the room with large heat dissipation, but only for cooling. For example, textile factories, advanced public buildings, etc., the use of slit air supply has been adopted.
2. vents are supplied by hot and humid air. They are ejected from several vents at the side of the room and are returned at a certain distance. The working area is in the course of circumfluence. This air supply mode has high wind speed, long range, slow attenuation of speed and temperature, and even temperature distribution. The utility model is suitable for public buildings such as large stadiums, halls, theaters and large factories.
3. diffuser, air diffuser, air supply can be delivered and delivered side by side. It also performs heat exchange in the air recirculation zone. The jet and return flow are short, and the effect is better when the attached jet is formed along the top gate. It applies to a room with a top grid.
Orifice plate, jet diffusion and indoor air mixing speed, the air temperature and velocity in the work area are relatively stable, suitable for the regional difference and the wind speed of working area is strict, room temperature fluctuation situation allows. Ventilation duct season maintenance method:
1, the unit's internal cleaning: if the crew leader time operation, in order to ensure the cooling effect, the machine must be cleaned 1 or 2 months;
2, unit maintenance: should pay attention to chassis cleaning, should be every day by "cleaning" key cleaning, prevent bacteria, odor happen.
3, unit cycle maintenance: unit running 1 - 2 months, such as wet curtain, filter screen plug or chassis is too dirty, should be made cleaning, lest cause machine fault.
