Abstract
A thermally-powered active master and passive satellite or slave diffuser system is disclosed. The system includes a master diffuser (24) with a displaceable damper assembly (41) mounted in the diffuser housing (31) and a thermal sensor-actuator assembly (46) positioned proximate the damper assembly (41) and proximate the master outlet (34, 58). An induction channel (47) communicates secondary air from proximate the master discharge outlet (34, 58) to the thermal sensor-actuator assembly (46) for accurate control of modulation by the damper assembly (41) of air flow to both the master (24) and passive slave (26) diffusers. The thermal sensor-actuator assembly (46) is capable of both cooling and heating and employs opposed sensor-actuator units (81, 102, 111) with override mountings (126, 128, 141) to effect changeover between heating and cooling.
