The core components of fresh air handling units (especially direct expansion type) include the direct expansion heat exchanger and expansion valve. Some products utilize technologies such as fully enclosed scroll compressors, copper tube-clad aluminum finned evaporators/condensers, and thermostatic expansion valves.
Variable frequency fresh air handling units can automatically switch operating modes based on outdoor ambient temperature to achieve energy-saving operation. Furthermore, some units support installation designs with extra-long ductwork (e.g., 150 meters) and significant elevation differences (e.g., 50 meters).
Fresh air handling units are used in medical fields such as makeshift hospitals, industrial fields such as cleanrooms, and commercial building fields such as commercial office buildings to provide air handling and ventilation solutions.
