The vertical air temperatures 12 m away from the wet pad are given in Fig. 9.Combined with
the results obtained 28 m away (Fig. 8(b) and (c)), it can be found that the temperature gap between the ends of the lower part (1.5 m and 3 m) gradually decreased with increasing distance from the evaporative pad. For example, at 12 m, the temperature difference in the lower part was 2.5 C; at 28 m, the gap was reduced to 0.5 C in the EC + ES working mode, which means that the distribution in air temperature in the second half (near the fan) of the greenhouse is even more pronounced than in the first half (near the pad).
