Air conditioning apparatus is disclosed. The apparatus is a terminal of the mixing type, receiving primary conditioned air, and delivering that air or a mixture including that air and recirculated air as required, for air conditioning. The rate at which primary conditioned air is delivered to the zone is varied between a maximum and a predetermined lesser rate as the air conditioning load on the space varies between a maximum and an intermediate load. The apparatus also includes a blower, nozzle or the like for inducing a flow of air from outside, and for mixing the induced air with primary conditioned air, so that such mixture is delivered to the zone. According to preferred embodiments which are disclosed, the apparatus is effective to deliver to the zone such a mixture of primary conditioned air and induced air under all conditions of air conditioning load on the zone. One disclosed mixing unit induces a flow of air from a closed zone surrounding the induction portion, and provides temperature control by admitting primary air, room air, heated air or mixtures, as required, to the closed zone.
