AI Technical Summary

Technical Problem

When the indoor air conditioner is installed and used, insufficient air inlet volume will cause the indoor heat exchanger to freeze, and the lower side of the electrical box is too close to the indoor heat exchanger, which is easy to produce condensation and cause short circuits and fires of the computer board, which poses a major safety hazard.

Method used

By providing a sealed space on the lower side of the electrical box to isolate the temperature transfer of the indoor heat exchanger and a dual-channel structure inside the housing, the air inlet of the first channel is stronger than the second channel to increase the air inlet volume.

Benefits of technology

It effectively avoids short circuits and fires caused by condensation inside the electrical box, ensures safety of use, and improves the working reliability of indoor heat exchangers, and avoids icing.
