  • Modular air conditioning system
    Patent number: 5485878
    Abstract: A heating, ventilation, and air conditioning (HVAC) system is disclosed which is capable of receiving interchangeable ventilation modules having varying degrees of air mixing abilities. A ventilation module fits inside the HVAC system and connects to a return air opening, an exhaust duct, an inlet air opening, and a supply air duct for proper routing of air to be conditioned. As ventilation needs change, a different module with appropriate ventilation characteristics can replace the existing module while keeping intact all other components of the HVAC system such as blowers, compressors, heaters, condensing coils and the like.
