[Abstract]:The mathematical model of the closed heat source tower is established, and the numerical simulation of the heat source tower under spray condition is realized by using MATLAB program, and the calculated results are compared with the experimental results. The distribution of spray solution, carrier heat fluid and air enthalpy in the closed heat source tower under spray condition is obtained by using the program. The results show that the air enthalpy in the tower is linearly distributed, and the heat transfer effect of the upper half of the finned heat exchanger is better than that of the lower half. The frosting phenomenon occurs first near the middle position of the tower. The air dry ball temperature is higher than 5.1 鈩，
