摘要
以实际营运船舶额定工况下空调负荷为基准,首先从热平衡角度,分析利用柴油机缸套冷却水余热制冷的可行性.其次以特定船舶中央空调所需冷量为标准,对吸附式制冷系统的核心部件吸附床进行初步设计.最后对吸附单元进行传热传质数值计算,分析吸附床厚度、缸套水流速、硅胶填充密度及硅胶比热容对吸附床传热性能的影响.
In this paper,the heat load of ship＇s central air conditioning system at nominal working condition was used to evaluate the feasibility of the application of adsorption refrigeration by employing the cooling water of the marine diesel engine as heating source.The silica gel-water was selected as working pair.An adsorbent bed,specially designed to conform to the working condition on ships,was developed.Finally,numerical simulation for the heat transfer enhancement was carried out on a typical tube of the adsorbent bed.Comparisons were made for the influence on the performance of the adsorbent bed by the thickness of the adsorbent layer,the cooling water capacity,the packing density and the specific heat of the silica gel.
