Aluminum alloy tuyere has positive pressure air-conditioning room automatic exhaust, usually by the self weight of the louver of the tuyere and natural droop, blocking the air exchange in the table of the room, when the indoor air pressure is greater than the outdoor air pressure, the air flow will blow the louver open and exhaust outwards, on the contrary, when the indoor air pressure is less than the outdoor air pressure, the air flow cannot flow into the room in reverse, the tuyere has a one-way check effect.
When the orifice plate is used for air supply, the wind speed is uniform and small, and the regional temperature difference is also small. Therefore, for air-conditioned rooms with strict requirements for regional temperature difference and wind speed in the operation area, large air supply volume per unit area, small room temperature allowable fluctuation planning, and high requirements for constant temperature and purification, orifice air supply method should be selected. The air conditioning direction of the single-layer louver is one-dimensional, either horizontal left-right or vertical up-down, but the air conditioning direction of the double-layer louver The air conditioning direction of tuyere is two-dimensional, with horizontal left and right and vertical up and down two directions.
Aluminum alloy tuyere is commonly used for air suction and supply in the pipeline. The specification and scale of single-layer louver tuyere can be promoted. At the same time, herringbone gate (multi leaf split regulating valve) can be equipped according to the actual situation to control the air volume or install aluminum alloy filter for supporting use. The blade can be divided into two types: horizontal and vertical. It can flexibly roll left and right or up and down to control the air flow direction.
When the air outlet, the difference between the inside and outside of the air conditioner should be considered. The air conditioning load of the inner room is small and the change is not big. The air conditioning effect is simple. In order to cooperate with the architectural decoration planning, the air distribution of the inner room of the air conditioning can be slightly worse than that of the outer room of the air conditioning. The total width of the narrow edge of the aluminum alloy tuyere is only 150 mm or 200 mm, and the folding edge is very small, so it is necessary to accurately size the opening of the ceiling. When planning the slot type air vent, it should be prevented from being too long. The extra long slot type air vents are connected one by one.
