Abstract：Research proposes: Through comparing and analyzing of the two kinds of systems, it was well known the main difference and each characteristics of the open /shut ventilated system and the shield system. As far as the profession of air condition and ventilated system is considered, in the aspects of engineering price and effect of constructing, it will be definite the advantages in the shield system compare to the open /shut ventilated system.
Research methods: In the aspects of system constituting, calculation in result, ventilated engine room and equipment's arranging, contrast method is adopted to precede the comparison. At the same time, the aspects of the working expenses, the constructing price and early investment in equipment are compared and analyzed. The author made a technique economy comparison and analysis.
Research results: From this paper, we know that the shield system is less than the open /shut ventilated system in the working expenses. On the early investment, include the early investment in equipment and construct price, the shield system saves to invest more one million Yuan.
Research conclusions: Only as far as the air condition and ventilated system is considered, whether on the early investment or in the working expenses, the shield system has greater advantage than the open/shut ventilated system in Tianjin. Further confirmed, it is available that air condition and ventilated system was changed from the open/shut ventilated system to the shield system during the first step designs of Tianjin subway No. 2 line.
