A blow molding machine with air conditioning that while minimizing the introduction rate of outside air, realizes maintaining of constant temperature in not only a plant building but also the interior of a blow molding machine and production of a bottle as a final configuration with stability in its measurement value. The blow molding machine with air conditioning is constructed so that air for use in biaxially stretching blow molding together with hot air of heating zone (1) and internal air of a plant building is suctioned by means of suction chamber (4), filtered by means of primary filer (6) and secondary filter (7) into clean air, brought into heat exchange with primary cooling coil (8), fed under pressure by air blower (10) and released through low-temperature duct (12) into the interior of the plant building. Further, the construction is made so that housing (3) on its side face is provided with vent (3a) so as to allow reflux of the clean air released into the interior of the plant building and flow i
