CPC Subclass Not Allocatable
F24F AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING (removing dirt or fumes from areas where they are produced B08B15/00; vertical ducts for carrying away waste gases from buildings E04F17/02; tops for chimneys or ventilating shafts, terminals for flues F23L17/02)
Description
F24F covers systems and apparatus for controlling indoor air quality and environmental conditions through cooling, heating, moisture regulation, and air movement. This subclass encompasses air conditioning units, ventilation systems, air humidifiers and dehumidifiers, and devices that utilize air currents for dust or particle screening purposes. It includes both centralized climate control systems and localized air treatment equipment used in residential, commercial, and industrial applications. Related heating and combustion systems are classified separately under F24B and F24D.
