本文针对用户使用吸收式机组中忽视的问题进行分析，指出吸收式机组的使用寿命并非人们想象的那么短，采取真空度控制、水的控制、溶液的控制和易损件的定期更换等措施可延长溴化锂机组的寿命，并保证机组长期具有优越的性能。作者推荐定期检测吸收器损失，从而了解机组的运行状况、进行机组真空度的检测和控制。 This paper analyzes the problems that users neglected in absorption units and points out that the service life of absorption units is not as short as people think. Vacuum control, water control, solution control and periodic replacement of wearing parts can be taken Extend the life of lithium bromide units, and ensure the unit has long-term superior performance. The author recommends to periodically detect the absorber loss, so as to know the operation status of the unit and to detect and control the vacuum degree of the unit.
