AI Technical Summary

Technical Problem

In the existing water system of the outdoor unit of a dual-supply air conditioner, the expansion tank installation method poses a risk of falling off, which increases the difficulty of production and assembly, makes maintenance inconvenient, and reduces production efficiency.

Method used

The space is divided into a first chamber and a second chamber by setting a partition inside the outdoor unit. The fan and air refrigerant heat exchanger are located in the first chamber, while the compressor, water refrigerant heat exchanger and expansion tank are arranged side by side in the horizontal direction in the second chamber. The expansion tank is close to the side wall of the shell and has an inspection port. The design is compact and easy to maintain.

Benefits of technology

This design achieves a compact arrangement of the expansion tank and the compressor or water refrigerant heat exchanger, reducing assembly difficulty, improving production efficiency, and facilitating the maintenance and repair of the expansion tank.
