Delivery device for conditioned air at a central air conditioning system

摘要

A variable flow, modular-type terminal unit for conditioning rooms in a centralized conditioning system is provided with means for controlling the conditioned air flow arranged within the outlet diffuser in order to vary the cross-section area of the outlet ports, being operated by a thermostatic device. The thermostatic device, directly fed with conditioned air operates such controlling means through a control lever, a control rod displaceable in the direction of its length and a triangular lever hinged at one vertex for rotation in a plane parallel to that where the control lever is pivotedly mounted. The operating member of the thermostatic device engages the control lever through the end of a threaded rod adjustable for setting the operation temperature. Other two adjusting screws are provided for hand control of the maximum and minimum cross-section opening of the diffuser outlet ports, by limiting the control lever rotation in two opposite directions.
