The invention relates to a solar heat collecting, heating and heat insulating curtain wall and roof and solar air conditioner system which comprises a solar heat collecting, heating and heat insulating curtain wall and an air conditioner equipment pipeline system. The solar heat collecting, heating and heat insulating curtain wall is composed of a heat insulating mortar leveling layer 11, a fireproof heat insulating plate 12, a cavity layer 13, a solar heat absorption water tank 14, a panel solar heat absorbing water tank 14', a water tank connecting pipe 14L, a heat insulating frame 15, a sun shielding roller blind 1A, a lighting glass panel 16, a clamping and fixing bar 17 and a ventilation air conditioner system 4-1. In winter, an air conditioner ground is directly heated through a heat exchange water tank 44; and in summer, the sun shielding roller blind is put down for preventing direct irradiation of sunlight, refrigerant water is provided for the air conditioner ground and the solar heat absorption water tank for refrigerating through a water source heat pump or an air source hat pump. In addition, the ventilation air conditioner system can be used for directly conveying cool air of summer in the curtain wall and warm air of winter in the curtain wall into a room, the cool air forms convection with hot air in the room and the warm air forms convection with cold air in the room, and the purpose of greatly reducing energy consumption of an air conditioner is achieved.
