AI Technical Summary

Technical Problem

Traditional ceiling-mounted indoor units have low refrigerant detection efficiency, are easily affected by airflow, and have a limited detection range. They cannot respond to refrigerant leaks in a timely manner, and the air guide plate cannot completely seal the air outlet, resulting in a high leakage rate.

Method used

The unit adopts a refrigerant detection structure, including a centralized detection chamber and a heat exchanger outer chamber, and is equipped with a gas collection pipe, air guide plate, flow guide plate and refrigerant detection device. The detection efficiency is improved by sealing the detection chamber and guiding the airflow.

Benefits of technology

It effectively reduces airflow interference during refrigerant detection, improves refrigerant accumulation efficiency, reduces air leakage rate, ensures refrigerant concentration is within the detection range, and improves the overall efficiency of refrigerant detection.
