AI Technical Summary

Technical Problem

In extreme low-temperature environments, the existing centrifugal air conditioning unit's antifreeze protection device may result in insufficient heating due to a single heating method, affecting the lifespan of the unit's core components.

Method used

A segmented heating method is adopted, in which the airflow is initially preheated by heating lamps and then fully heated by heaters to ensure stable and uniform airflow temperature and prevent damage to the unit from sudden temperature changes.

Benefits of technology

It achieves stable heating of airflow in low-temperature environments, improves the antifreeze protection effect of the unit, and reduces the risk of damage to the core components of the unit.
