空气加热器厂家空气加热器的朋友都比较多，大部分问题都是空气加热器是否很节能，加热速度能否调解?空气加热器温度升高，空气粘度增大，气体雷诺数减小，传热强度减弱，空气加热器外貌温度升高，热损失增大。
Air heater manufacturers have more friends, most of the problems are whether the air heater is very energy-saving, heating speed can be adjusted? Air heater temperature increases, air viscosity increases, gas Reynolds number decreases, heat transfer intensity decreases, air heater surface temperature increases, heat loss increases.
这个问题取决于空气加热器的结构�？掌尤绕鞒Ъ抑荒芨谋浣涣鞯钠德�，这样会改变电机的转速，空气加热器不转动，热水器的频率不控制加热速度。我们有两种比较简单的要领，变压器电压变革小，优点是多级调理，缺点是电路结构比较庞大，生产本钱高。半波整流器是用来改变交流电的值，以抵达改变加热功率和加热速度的目的。该要领电路结构简单，操作便当�？掌尤绕鞯募尤人俣戎饕钦庋�，应该是合理的。想要提高空气热交换器的整体效率，我们可以做到的有：一是通过渐开线形状或阿基米德涡线，对风机和挡板形状进行适当调解，二是将正方形的外形进行切角处理，使其成为蜗壳，来降低风阻巨细。这样，通过以上这两个步伐，可以提高空气热交换器的整体效率，来抵达目的。
This problem depends on the structure of the air heater. Air heater manufacturers can only change the frequency of AC, which will change the speed of the motor, air heater does not rotate, water heater frequency does not control the heating speed. We have two relatively simple methods, transformer voltage change is small, the advantage is multi-stage adjustment, the disadvantage is that the circuit structure is more complex, high production costs. Half-wave rectifier is used to change the value of AC to achieve the purpose of changing heating power and heating speed. This method has simple circuit structure and easy operation. The heating speed of air heater is mainly like this, which should be reasonable. To improve the overall efficiency of air heat exchanger, we can do: first, through the involute shape or Archimedes vortex, the shape of the fan and baffle is adjusted properly; second, the shape of the square is tangentially processed to make it a volute to reduce the size of the wind resistance. In this way, through the above two measures, the overall efficiency of air heat exchanger can be improved to achieve the goal.
