Abstract
An air powered terminal unit comprising a housing, a fluid to air heat exchanger, an induced flow air inlet upstream of the heat exchanger, a venturi downstream of the heat exchanger, a nozzle cooperatively disposed with the venturi so as to direct a primary air jet discharged from the nozzle through the venturi, such that an air flow through the heat exchanger is induced, and an outlet downstream of the venturi for discharging a mixture of the induced flow air and the primary air.
