The invention provides a high-efficiency temperature-control solar heat utilization curtain wall system. The system is of a structure composed of a plurality of curtain wall units. Each curtain wall unit comprises an external heat collecting element, an internal insulating element and an air passage formed in the middle of the external heat collecting element and the internal insulating element; the external heat collecting element comprises outer glass and inner glass; the outer glass and the inner glass form a sealed hollow structure; the internal insulating element comprises a heat reflecting layer and inner glass; and the heat reflecting layer and the inner layer also form a sealed hollow structure, and the air passage is arranged between the inner glass and the heat reflecting layer. The system disclosed by the invention combines the solar heat utilization with a curtain wall of a building, so that the curtain wall system used as the building material has the solar heat collecting function, and various functions such as supply of domestic hot water for the building, heat preservation of the building, heat supply in winter, refrigeration in summer and the like can be achieved by heating the air.
