A prefabricated window unit with an air conditioning system in which cold or hot air is passed through hollow vertical and horizontal members forming a framework of the window unit, and the air is blown out through a blow part formed in the framework toward a room, whereby the room air is conditioned by thermal radiation to or from the framework and by the air blown from the framework. Hollow spaces formed in an upper horizontal member and a waist transom are partitioned into indoor side and outdoor side hollow space portions. In a windowpane frame section consisting of left and right vertical members, the upper horizontal member and the waist transom connected horizontally between the vertical members, are delimited a sealingly enclosed space including a blind by indoor side and outdoor side transparent plates mounted to the outdoor side portion of the windowpane frame section. The air is circulated from an air feed duct through the indoor side hollow space portions, the blow part, the room, a suction part on the framework, the sealingly enclosed space, and the outdoor side hollow space portion to an air recovery duct. Thus, upon air-conditioning, heat accumulated on the blind as irradiated by sunshine can be removed or absorbed by the conditioned air. |
