Absorption chiller mainly by the four exchange equipment composition, namely generator, condenser, evaporator and absorber, they formed two cycle loop: refrigerants circulation and absorber cycle.
The problems existed in circulation pump for evaporator are analyzed, and specific improvement measures which are proved to be reasonable by practice are then put forward.
分析了蒸发器强制循环泵存在的问题，并提出了具体改进措施。实践证明，这些改进措施是合理的。

Fouling removing or preventing evaporator of natural circulation is ideal to solve the fouling problem.
