摘要:
由于生产任务不足及工艺等方面原因,用于生产工艺冷却的制冷机组,常因制冷负荷偏小而停机,严重影响了生产工艺的安全与稳定运行.通过增设一旁路调节管路的方法,将部分冷却水引入到冷冻水系统中,解决了制冷机组停机问题,也避免了因其停机造成的经济损失.同时用热力学理论,对冷冻水系统中引入冷却水问题进行了讨论,获得了生产所需最小制冷负荷条件下引入冷却水量与制冷机组负荷率间的关系,及最大和最小引入冷却水量随制冷机组负荷率的变化关系,并最终确定了一个在整个生产波动范围内都不会停机的引入冷却水量,保证了生产运行的安全性和稳定性
Abstract:
Owing to underproduction and processes, the refrigerating equipment, by which the production processes are cooled, often stops. The production runs seriously bad. To solve this problem, a bypass is installed in the refrigerating system, and some cooling water is led to the chilled water system. Then, even if the production load changes greatly, the refrigerating equipment will not stop any more, and the production loss caused by the refrigerating stop has been avoided. According to thermodynamic theory, the issue about cooling water quantity, which is led from the cooling water system into the chilled water system, is analyzed. The led cooling water quantity at the minimum needed refrigerating load is obtained, and the maximum and minimum led cooling water quantities at different needed refrigerating loads are obtained too. Also, a certain led cooling water quantity, at which the refrigerating equipment will not stop any more on any needed refrigerating load, is determined. And the production running stability and security are ensured
