Project Profile

    Fangshan Line, one of the construction projects for the ***2 Beijing rail transit network, the main function is to meet the need of traffic to travel between the the Fangshan Metro Center City to improve the conditions of public transport. To speed up the Fangshan Metro construction, effectively ease the central city population and industry, promote the layout of urban functions to optimize. Subway Fangshan Line, a total of three required hot water, are the parking column check the library, the public security building, office building.

System Design

    In accordance with the actual situation of the project, Solatube sun design the entire project total water consumption of *0 tons, three solar hot water systems are pressurized secondary heat exchanger system. Allocated as follows:
    Parking for train inspection Library: 8 tons of water tank, **0 square meters of U-shaped tube solar collector;
    Public security floor: 8 tons of water tank, **5 square meters of U-tube solar collector;
    Integrated office: *4 tons of water tank, **3 square meters of U-tube solar collector.

System Features

    1. The system uses solar medium forced circulation heat exchanger;
    2. solar collector with U-shaped tube collectors, heat exchangers using the corrugated tube heat exchanger (this heat exchanger and the volume of heat exchanger, the heat transfer coefficient K is the traditional GB displacement of **2 times the heat reasonable diversion device into an organized flow of heat, reducing the cold water zone and the stagnant water zone is heated by natural; and maintenance side cheap line);
    3 .solar water tank for a closed pressure vessel;
    4. loop solar heating piping and circulating pumps wetted at a stainless steel tube;
    5.Cold water add the water treatment equipment;
    6.hot water at plus thermostatic valve;
    7.The control cabinet brushed stainless steel, internal use of the epoxy powder electrostatic spraying process, all internal components are Siemens, Schneider, ABB is equivalent to a grade or more products.
