你是不是一直在和通風櫃的风速作斗争？有人说0.5 m / s，有人说0.3 m / s，有些顾客就是觉得风速不够。人们想知道有多少风速？
　　其實通風櫃面风速在国内就没有强制的标准，现在都是参考美国和欧洲的标准，以及暖通的一些规范。到底有多少风是对的？实际上，通風櫃半开（300mm-350mm）风速0.5m/s可以满足大多数客户的使用。以下是一些不遵守的例子：
不滿足條件：室內負壓過高，已知房間負壓過高肯定會影響通風效果，即使排氣速度大，而不是負壓在空氣中過高的有效流量室內，也不能有效地排出通風櫥中的有毒有害氣體；

全钢通風櫃

条件二: 通風櫃导流板不合理！通风橱排气通风橱，使得导向板被均匀地排出的有效合理的手段。然而，由于该装置和结构设计速度的不同而变化的效果通風櫃。市场上的通風櫃大多是模仿的，很少有厂家真正有效地设计自己的，这也是大多数通風櫃的缺点。特别是变风量阀的应用，通風櫃更是如此;

當通風機的熱量過高時，熱輻射效應越大，相應的通風量越大，風速0.5m/s已不能滿足要求..
它不符合四个条件：当地大气压，空气湿度，温度等，这些都需要高度专业化的人员应进行计算。很简单。在西藏，当你设计风量和风压的时候，北京肯定有一个很大的差距,

My informant's head drooped low and she murmured, "It was I." I left him, found supper, and had been long asleep tinder a tree, when I grabbed savagely at some one for silently shaking me, and found it was Ned Ferry. His horse's bridle was in his hand; his face was more filled with the old pain than I had ever seen it; he spoke low and hurriedly. "Come, tell me what this means." I scorn to coax men for what I wish. Therefore, I must be disagreeable. In the heart of Girgaum, one of the suburbs of Bombay, at the end of a street, under a large areca palm an old man was selling grain and rice in open baskets. A whole flight of bickering sparrows settled on his merchandise, and he looked at them with happy good humour without scaring them away. Deeply graven in the stone of one of the walls is the giant hand of Ali the Conqueror, the terrible, who came from the land of the Arabs, killing all on his way who refused to be converted to Islam. And he died in the desolate Khyber, where all who pass do him honour, and entreat his protection on their way. Gauze and muslin dresses moved gracefully about against the background of bamboos and roses. Light footsteps scarcely bent the grass; the ripple of talk, with its sprinkling of Indian words, was sweet and musical. Fireflies whirled above the plants making little tendrils of light; there was dreaminess in the air—an anticipation of fairyland to which the music seemed the prelude. “Trap you?——” At noon Landor got his orders. He was to leave at four o'clock, and when he told Felipa she planned for dinner at three, with her usual manner of making all things as pleasant as possible, and indulging in no vain and profitless regrets. "We may as well have Mr. Brewster and Nellie McLane, too," she decided, and went off in search of them, bareheaded and dancing with excitement. She dearly loved rumors of war. The prospect of a scout was always inspiriting to her. But there was more stock than was needed. "Gi' me that licker fust," shouted Groundhog, but Shorty was already running back for Si. When he returned with him he threw the canteen to Groundhog with the order, "Go ahead and show us the place." "He slanders my sons and he slanders my daughters," he muttered to himself as he went home, "and I reckon as this time it ?un't true." HoME ww路741net路c0m ENTER NUMBET 00104ebony.org.cn
