In the embodiment of the present disclosure, the total heat exchange core includes a plurality of heat exchange membranes 130, and the heat exchange membranes 130 are used for heat exchange and moisture exchange. The plurality of heat exchange membranes 130 are stacked, and a support structure is arranged between two adjacent heat exchange membranes 130 to maintain a preset distance to form a sandwich layer, and the support structure defines an air flow channel in the sandwich layer. If the number of the heat exchange membranes 130 is n, the number of the air flow channels is n-1. For convenience of understanding, the embodiments of the present disclosure are illustrated by sequentially numbering the plurality of heat exchange membranes 130 from top to bottom, and sequentially numbering the plurality of air flow channels from top to bottom. The air flow channels with odd numbers in the multilayer air flow channels are first air flow channels, and the air flow channels with even numbers in the multilayer air flow channels are second air flow channels. The first air flow channel is communicated with the first direction, and the second air flow channel is communicated with the second direction. The first direction is the direction different from the second direction, the air inlet of the first direction is staggered with the air inlet of the second direction, and the air outlet of the first direction is staggered with the air outlet of the second direction.
Illustratively, the heat exchange membrane 130 is rectangular, and a plurality of heat exchange membranes 130 are stacked to form a heat exchange membrane group. The heat exchange membrane assembly is a cube and is provided with four sides, wherein the four sides are a first side, a second side, a third side and a fourth side in sequence. The first side is opposite to the third side, and the second side is opposite to the fourth side. The first direction is from the first side edge to the third side edge, and the second direction is from the second side edge to the fourth side edge. Therefore, the air inlets of the first air flow channels are positioned on the same side, and the air inlets of the second air flow channels are positioned on the same side. When the full heat exchange core is installed, the first side edge corresponds to a first air inlet of the fresh air machine, the second side edge corresponds to a second air inlet of the fresh air machine, the third side edge corresponds to a first air outlet of the fresh air machine, and the fourth side edge corresponds to a second air outlet of the fresh air machine. The air of the fresh air machine entering from the first air inlet flows through the plurality of first air flow channels and is discharged from the first air outlet; and air entering the fresh air fan from the second air inlet flows through the plurality of second air flow channels and is exhausted from the second air outlet.

The first electrode and the second electrode are opposite electrodes for forming a high voltage direct current electric field between an adjacent pair of the first heat exchange film 131 and the second heat exchange film 132.
When air flows through the high-voltage direct-current electric field, the air is ionized to generate a large number of electrons and ions, and the electrons and the ions move to two poles of the high-voltage direct-current electric field under the action of the electric field force. The electrons and ions encounter dust particles in the air during movement and cause the dust particles to be charged correspondingly. The charged dust particles move to both poles of the high voltage dc electric field by the electric field force, and are adsorbed on the surfaces of the first and second heat exchange films 131 and 132. The flowing electrons and ions create a corona current that can break down cell walls composed of proteins, thereby killing bacteria in the air.
