船舶伙食冷库压缩机制冷量的预测

船舶伙食冷库的所配用的压缩机制冷量同伙食冷库的库容大小存在着一定的函数关系,本文通过实船设计的样本数据采用曲线拟合的方法,推导出压缩机制冷量关于冷库库容的函数,并由此生成冷库库容和压缩机制冷量的关系曲线,对于在设计初期快速预测伙食冷库制冷压缩机的制冷量有实际应用意义.

Prediction of Refrigerating Capacity of Compressor in Shipboard Provision Cold Store

In a shipboard provision cold store,there should be a functional relation between the refrigerating capacity of the compressor and the store's volume.In this paper,based on some sampled data from several ships that have been designed,and by use of a curve fitness method,a functional relation equation between the refrigerating capacity and the volume is derived,and a useful relation curve between the two is generated from the equation.The effort is of practical meaning to quickly predict the refrigerating capacity necessary for a provision cold store in preliminary design.
