METHOD OF WATCHING CONDENSER PERFORMANCE AND SYSTEM THEREFOR

摘要

A method of watching the performance of a condenser and a system for carrying such method into practice, wherein a cooling water temperature, a cooling water flow rate, a condenser temperature and/or a heat flux through walls of cooling water tubes of the condenser are sensed by sensors to obtain values representing the operating conditions of the condenser, and an overall heat transmission coefficient or a heat transfer rate of the cooling water tubes is calculated at an arithmetic unit from the values representing the operating conditions. A cleanness of the cooling water tubes is calculated by an arithmetic unit from the value of the overall heat transmission coefficient or the heat transfer rate, and the performance of the condenser is judged by a performance judging unit based on the cleanness of the cooling water tubes.
