【 摘 要 】

The working environment of the air-cooled condenser is very complicated. By analyzing the heat transfer process of the air-cooled condenser, it is found that the temperature of the environment, the lateral wind speed in the environment and the rotational speed of the axial fan all have an influence on the condensation capacity of the air-cooled condenser. Through research, it is found that the condensation capacity of the space-time condenser at -25 ° C is about 3.75 times that at 30 ° C; compared with no lateral wind speed, when the wind speed increases from 4m/s to 12m/s, the decline of the condensation capacity of the air condenser changes from 1.2% to 12.6%; when the axial fan is at 1.1 times rated speed, its condensation capacity is 1.6 times that of 0.5 times. It can be seen that the rotational speed of the axial flow fan and the ambient temperature are the main influencing factors, and the rotational speed of the axial flow fan is an active adjustment factor. Furthermore, the control scheme of the axial fan speed as a function of ambient temperature can be obtained through analysis.
