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.

DETAILED DESCRIPTION It is therefore one aim of the present invention to provide a prefabricated window unit with an air conditioning system in which a cooling and heating efficiency is improved.
A more specific aim of the present invention is to provide a prefabricated window unit with an air conditioning system in which air-conditioning in a room would not be disturbed, even when sunshine irradiates the room directly through the window.
According to one feature of the present invention, there is provided a prefabricated window unit with an air conditioning system, in which a blind (Venetian blind or a louvre) is disposed within a sealingly enclosed space delimited between outdoor side and indoor side transparent plates mounted to a window frame to shield sunshine, and heat applied to the blind from the sunshine is removed or absorbed by passing conditioned air that is blown out of the window frame into a room and then recovered to the window frame, through the sealingly enclosed space containing the blind.
According to a more specific feature of the present invention, there is provided a prefabricated window unit with an air conditioning system comprising a rectangular framework consisting of left and right vertical members, an upper horizontal member and a lower horizontal member, a waist transom disposed between and connected to the left and right vertical members, a sealingly enclosed space delimited by indoor side and outdoor side transparent plates mounted to the outdoor side portion of a windowpane frame section consisting of the left and right vertical members, the upper horizontal member and the waist transom, a blind or louvre disposed within the sealingly enclosed space, indoor side hollow space portions formed in the upper horizontal member and the waist transom, respectively, so as to open at and communicate with hollow space portions in the vertical members, outdoor side hollow space portions formed in the upper horizontal member and the waist transom, respectively, so as to open at and communicate with the sealingly enclosed space, an air feed duct connected to the indoor side hollow space portion in the upper horizontal member, an air recovery duct connected to the outdoor side hollow space portion in the upper horizontal member a blow port for opening one of the indoor side hollow space portions formed in the waist transom toward a room, and a suction port for opening one of the outdoor side hollow space portions formed in the waist transom toward the room
