设备费用低,气流分布效果好,这是一家瑞典公司研制的两种新的工业通风、采暖系统的特点。一种系统是靠高紊流和高风速动量的合理作用;另一种系统完全是用没有紊流的低速空气扩散。喷口(射流)-屏幕系统瑞典对苏联巴杜林发明的单点送风技术作了改进,并制成南模数构件组成商品化系统。在本系统中,从屋顶机组或屋顶下装置送出的热风横贯建筑物的上部空间。射流诱导室内空气,在工作区内形成反向气流,使温度横向竖向都很稳定。该设计使从地板到屋顶竖向最大温差为2℃,厂房内横向最大温差为3℃。工作区的空气流速保持0.2～0.5米/秒。射程限制在喷嘴至对面墙距离的60％～75％范围。实际情况表明,如果射程为整
The low equipment cost and good air distribution effect are the characteristics of two new industrial ventilation and heating systems developed by a Swedish company. One system is based on the rational action of high turbulence and high wind momentum; the other system is completely diffused with low velocity air without turbulence. Spout (jet) - screen system Sweden made improvements to the single point air blast technology invented by the Soviet Union Baturulin, and made a modular system consisting of South modulus components. In this system, the hot air sent from the roof unit or the under-floor unit traverses the upper space of the building. The jet induces indoor air and forms a reverse air flow in the work area, so that the temperature is vertically and horizontally stable. The design has a maximum vertical temperature difference of 2°C from the floor to the roof, and a maximum temperature difference of 3°C in the horizontal direction in the building. The air flow rate in the work area is maintained at 0.2-0.5 m/s. The range is limited to 60% to 75% of the distance from the nozzle to the opposite wall. The actual situation shows that if the range is full
