空冷散热器防冻系统的研究

Researching on Prevent Frostbite System of Dry Cooling Radiator

介绍了空冷系统，分析了空冷系统在我国北方地区冬季冻损的原因，提出一种冬季用于空冷散热器防冻、夏季用于加热给水的可切换复合系统方案，阐述了该系统的运行方式。通过定性和定量分析，结果表明：系统的构思合理、可行，不仅具有可靠的防冻效果，且具有明显的节能效益，应用前景广阔，值得推广。

This paper introcduces a vapor refrigeration system,analyses the caution why the vapor re frigeration system is frozen and damaged in winter in the North of china and advances a swithable compound system which is used to keep the vapor refrigeration radiator from fraezing in winter and heet feedwater in summer. By guantitative and gualitative analysis,the results shows that the plot of the system is reasonable and feasible. The system has reliable effect on preventing frostbite and saving energy. It will be used in a vast range of prospects and be worth be spread
