[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and the indoor air is exhausted through the duct. The ductless fresh air system consists of a fresh air fan, which also purifies the outdoor air and introduces it into the room. When the fresh air system is in use, a double-sided line wiring board is used to make the line distribution more organized.

[0003] Traditional double-sided wiring boards for fresh air systems are mostly designed with holes to facilitate threading. However, since the holes are of uniform size and the wires used are of varying thicknesses, it is difficult to pass wires of different sizes through them. This results in smaller wires becoming loose when passing through the holes, while larger wires are difficult to pass through the holes, thus limiting their use.

[0004] In order to solve the above problems, the present application provides a double-sided circuit arrangement board for a fresh air system. Utility Model Content
