At present, the electric auxiliary heat of the air duct machine is fixedly installed between the fan assembly and the heat exchanger assembly through the electric auxiliary heat connecting piece and the electric auxiliary heat installation frame. The installation of electric auxiliary heat between the fan assembly and the heat exchanger assembly must not only consider the space required for the installation of electric auxiliary heat, but also consider the impact of electric auxiliary heat on the heat exchange efficiency of the heat exchanger. Moreover, if the electric auxiliary heat is damaged, it is very inconvenient to disassemble the casing of the air duct machine or even the heat exchanger assembly for maintenance or replacement. In addition, the difference between the air conditioner models that include electric auxiliary heating and the air conditioner models that do not include electric auxiliary heating is only whether electric auxiliary heating is included, but the models need to be managed separately, which doubles the number of air conditioner models, giving production and sales departments Model management adds to the difficulty. Due to the location where the electric auxiliary heat is installed in the existing air duct machine, it is difficult to disassemble and assemble the electric auxiliary heat, so the air duct machine with electric auxiliary heat and the air duct machine without electric auxiliary heat can only be produced and sold separately. Moreover, when one of the models is in short supply, they cannot quickly replenish each other. If you want to replenish, you can only do it through complicated rework, which reduces the coordination between related models.
