Abstract
A forced airflow air conditioning system includes a humidifier which is operable to humidify air bypassed from a supply air plenum to a return air duct or vice versa, the humidifier airflow being controlled by a damper closure member which is operably connected to a bimetal spring actuator or to an electric motor, both responsive to temperature of air flowing through the system. One embodiment includes an electric motor connected to the damper closure member and in circuit with a humidistat for opening the damper when humidification is required.
