Geothermal effects on the underground water conveyance pipe system have been investigated through the multi-regional water supply system from Paldang water intake station. To make an investigation of raw water thermal energy, temperature sensors are installed the surface of the pipes of metropolitan area water supply system. In 2009 winter and early spring seasons, the monthly averaged temperatures at Paldang 2 intake stations are 1.94℃ in February, 4.96℃ in March, and 10.56℃ in April. After the transfer in 26.0 km distance of tunnel and buried pipe, the raw water temperatures are raised to 3.13℃, 6.04℃, and 11.39℃ respectively. As the temperature difference between the raw water and the air reduces, the temperature increasement is reduced by 1.19℃ in Feb., 1.08℃ in Mar., and 0.83℃ in Apr. Since the flowrate is over 1,150,000 m3/day, it is estimated that the water exchanges a huge amount of heat over 1.0 Tcal a day with the ground. |
