Summary
Highlights
The assembly of the indoor unit proceeds with seal plate installation, attachment of sealing materials to the drain pan, and installation of the cross-flow fan and heat exchanger. Electrical equipment is then installed, followed by leakage and operating inspections to ensure proper functionality. Finally, the front grill is installed, and a withstand voltage test is conducted.
The video begins by showcasing the molding processes for various indoor unit components, including the indoor grill, indoor frame, and cross-flow fan. This is followed by ultrasonic welding to join molded fan parts and a balance inspection process.
This section focuses on the creation of the heat exchanger, starting with hairpin processing where straight copper tubes are bent into a U-shape. These U-shaped tubes are then inserted into aluminum pinholes, followed by bending the heat exchanger and U-tube insertion to create a single path. Soldering processes join copper pipes, and pressure sealing and leakage inspections ensure structural integrity.
The production of the outdoor unit begins with pressing and painting processes for its components. Resin molding for various parts, including the propeller fan, is also shown. The assembly involves installing a coupler, applying putty, and attaching soundproofing material to the compressor. The propeller fan and side plates are then installed.
The assembled outdoor unit undergoes a withstand voltage test to check for abnormalities. A machine nameplate is attached, and then both indoor and outdoor units are prepared for packaging, signifying the completion of the manufacturing process.
