If desired, a series of room units may be so connected by conduits connecting the upper chambers 11. These units may be placed in tandem or series without interfering with the balancing of the various units since damper arrangement 13 permits a desired static pressure to be maintained in the lower chamber 12 of each unit. This arrangement provides many advantages from the standpoint of economy in manufacture and installation of the system.
- pumps 116, 124 supply medium, either hot or cold water depending upon conditions exteriorly of the building structure and seasonal conditions, to the heat exchangers 4 of the various room units.

- Jets of air are discharged from chamber 12 through nozzle members 23 at a predetermined velocity.
- Primary air discharged through nozzle members 23 induces secondary air from the area being conditioned through inlet 6 and heat exchangers 4 in heat exchange relation with heat exchange medium passing through the coil.
- the stream of secondary air after passage through heat exchanger 4 mixes with the streams of primary air being discharged from nozzle members 23.
- the mixture of primary and secondary air is discharged through outlet 7 into the areas being con di-tioned.
- the damper may extend along a substantial part of the unit length if desired to assure uniform distribution of treated air within lower chamber 12 of plenum 10.
