[0029] Such as figure 1 Shown: a fresh air pretreatment geothermal exchange system, which includes three parts: an outdoor fresh air intake part, a ground heat exchange part and an indoor fresh air treatment part connected by a ventilation pipe. The outdoor fresh air intake part is set on the ground, and the outdoor fresh air intake The part includes fresh air outlet 1, medium-efficiency filter device 3, electrostatic precipitator 4, solid dehumidification device 5 arranged in order from top to bottom; fresh air outlet 1 is greater than or equal to 2.0m from the ground, and coarse-efficiency filter is installed in fresh air outlet 1. 2. For particle size ≥5.0μm, filtration efficiency 90>E≥70%; medium-efficiency filter device 3. The initial resistance of the medium-efficiency filter is about 50-90Pa, the final resistance is about 100-180Pa, and the particle size is ≥ 1.0μm, filtration efficiency 99>E≥70%. The solid dehumidification device is a cylindrical solid adsorption and d...
