The invention discloses an anti-ice blockage method of a plate type evaporator. According to the anti-ice blockage method, a pressure balance valve is not used for preventing ice blockage, but a common electromagnetic valve is used for preventing the ice blockage, so that the anti-ice blockage cost is greatly reduced; compared with the pressure balance valve, the electromagnetic valve has the advantages of high accuracy, light weight and accuracy in control, no ice in the evaporator is guaranteed, and the ice blockage phenomenon of the plate type evaporator is completely eliminated. 本发明公开了种板式蒸发器防冰堵方法，本发明不再采用压力平衡阀来防止冰堵，而是采用普通的电磁阀即可达到防冰堵的效果，大大降低了防冰堵成本，采用电磁阀相对于压力平衡阀精度更高，重量更轻，而且控制更加精确，保证蒸发器内无结冰，彻底消除了板式蒸发器的冰堵现象。
