摘要

搭建了真空制冰动态特性实验台，在相同起始温度、预设压力下改变喷射流量，通过对闪蒸室内温度、压力等参数的采集，分析了流量及固体吸附模块对动态二元冰制备过程的影响。研究表明流量越大平衡态压力越低，平衡时闪蒸室内温度基本不变，维持在0℃左右；通过对含冰率的测定发现过高流速并不利于冰晶的生成，较低喷射速度下成冰率相对较高；吸附条件下易形成动态平衡环境，且更有助于维持较低的平衡压力。

Abstract

A test bench was built to study the dynamic characteristics of a binary ice vacuum system. The tests started with the same initial temperature and preset pressure but different jet flow. By collecting the indoor parameters of the flash such as temperature

pressure and so on

the influence of flow and solid adsorption module on the dynamic binary ice preparation process was analyzed qualitatively. The results showed that of the higher the flow rate

the lower the equilibrium pressure

while indoor balance temperature of the flash basically remained unchanged

maintaining at about 0℃. Through measuring the content of ice

it was found that the high flow rate was not favorable to the formation of ice crystals

while the low injection rate was relatively good for it. With adsorption it was more likely to achieve the dynamic balance and to maintain the balance at low pressure.
