The single air inlet fan assembly is composed of a single air inlet motor and an air duct shell. A fully symmetrical heat exchange core 7 is arranged in the casing 1. The fully symmetrical heat exchange core 7 is a hexagonal core. The upper and lower sides and the left and right sides of the hexagonal core are symmetrically fixed to the casing 1. In the middle, the upper and lower sides and the left and right sides are divided into four spaces by partitions 8, and the four spaces correspond to the outdoor air inlet 2, the outdoor air outlet 3, the indoor fresh air outlet 4 and the indoor return air outlet 5, respectively. A primary filter 9 is set in the space corresponding to the outdoor air inlet 2 and the indoor return air outlet 5, and a high-efficiency filter 10 is set in the space corresponding to the outdoor air outlet 3 or the indoor fresh air outlet 4. A lower inspection port 11 is set on the bottom surface of the casing 1, and a detachable inspection door panel 12 is set on the lower inspection port 11. The main feature of this solution is that a fully symmetrical heat exchange core 7 is arranged in the casing 1. The fully symmetrical heat exchange core is a hexagonal core.
