"换热器温度控制方式 旁通和直接流量调节 方式的选择",

"换热器温度控制方式,通过流体进行旁通调节 实现温度控制 与直接流量调节的区别?分别用什么场合?适用?",

"这就要看你是以什么为主参数的了! 如果你 只要控制的是温度 那么 �量量的大小对后面没有影响 可以用流量控制! 但是 实际工况下 �量量的稳定大于温度参数 �所以 才会选用旁通流量控制温度的手段!",

"主流量调节 控制温度 会影响正常工况下主流量的介质流量 在温度变化不大的情况下 �量量调节影响影响较小 但是 对于温度变化较大的情况 流量调节时 �量变化较大 � � 但是 通过旁通调节 �能实现主管路 �量不变 而对对正常工况几乎没有影响!\"",
