Why the Evaporator Adopts Sprayer and the Absorber Adopts Spray Plate?
In Hope Deepblue's LiBr absorption chillers, refrigerant water is kept clean to minimize the risk of blockages in the system. The refrigerant water is transferred by a pump and sprayed onto the surface of the heat exchange tubes via a sprayer. This process increases spray density, enhancing the evaporation effect. In the event of abnormal conditions, the spray process can be immediately stopped to prevent freezing of the heat exchange tubes. However, in the case of the spray plate, residual refrigerant water remains in the plate and continues to drip onto the heat exchange tubes, potentially causing the tubes to freeze if not addressed promptly.
The volume of LiBr solution in the absorber is limited, and when spraying with nozzles, there is a risk that some of the LiBr solution may be sprayed outside the absorber, where it could drip directly into the dilute LiBr solution. This results in the wastage of valuable LiBr solution and can negatively affect the absorption efficiency. On the other hand, the spray plate device, with each row of small holes corresponding to a heat exchange tube, helps improve the absorption process. This arrangement ensures that the LiBr solution is more effectively distributed over the heat exchange tubes, enhancing the absorption effect and reducing solution loss.
