Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法，在不考慮燃燒的冷態情況下，研究了熱風爐燃燒室內的氣流分佈規律.在此基礎上，比較了2種不同設計方案的氣流流動特徵，尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和煤氣的流動和混合的影響.結果表明，阻流板的設計對加強空氣和煤氣的混合有著極為重要的作用，同時也增加了空氣管道的阻力損失，在同樣的工況條件下需要提高管道系統的總壓力The simulation results indicated that the air flow, airside pressure drop, water flow and flux of heat exchange in water side decreased with the increase of frosting time, and the airside pressure increased
模擬結果表明，隨著結霜量的增加，空氣側換熱器的換熱量減小，風量也將逐漸減小，而阻力卻迅速增加；水側換熱器的換熱量減小，水流量也減小。Ptc heater uses the ptc heating sensitive resistance as the heating source. it is widely use in the air - conditioner, warm drier and warmer etc. as the secondary heating. the resistance value of the ptc heater will rise or reduce with the change of the environment temperature as it makes the ptc heater has the features of energy saving, even heating, safe and long life. it is widely welcomed by a lot of customers
Ptc加熱器是採用ptc熱敏電阻元件為發熱源的一種加熱器，廣泛用於空調器的輔助加熱和暖風機取暖器等電氣設備上， ptc熱敏電阻元件因具有隨環境溫度高低的變化，其電阻值隨之增加或減小的變化特性，所以ptc加熱器具有節能恆溫安全壽命長等特點，被越來越多的用戶所歡迎。
