摘要
本文主要叙述船舶制冷系统变频控制时热力循环参数的计算。目的是了解系统在一定的蒸发温度下 ,当环境温度和转速变化时 ,热力循环中各状态点压力、温度以及系统制冷量、功率等物理量的变化情况 。
The calculation of thermodynamic cycle parameters is mainly introduced in the paper when the frequency is converted.The aim is to find the laws of the thermodynamic parameters' change under certain evaporating temperature and vario us environment temperature and rotating velocity of the compressor.The parameter s include pressure,temperature,refrigerating effect,power and so on.It is helpfu l to the understanding of the model of the controlled plant when a control syste m is established.
