Bu makalede, kış aylarında köprü ısıtmada
kullanılan deniz suyu kaynaklı bir pompası dizayn edilmiştir. Kışın özellikle
karlı havalarda köprü ve yolların donması pek çok kazaya neden olmaktadır. Bu
nedenle muhtemel kazaların önlenmesi açısından kar eritme sistemlerinin
kullanılması gereklidir. Optimum boru
boyunun belirlenmesi denizden ısı transferinin maksimum olması için önemli bir
kriterdir. Bu çalışmada boru çapı, et kalınlığı, sarmal çapı ve sarmal adımının
ısı transferine etkileri incelenmiştir. Ayrıca, sarmal borulardaki sürtünme
katsayısı ve pompaların enerji tüketimleri de hesaplanmıştır.

In
this paper, a seawater source heat pump system is designed for a bridge heating
in winters. It is probable to freeze of the ways and bridges which may cause
many accidents in the cold and snowy weathers. Snow melting system is necessary
to prevent the possible accidents and privative situations. Design of the
optimum pipe length of seawater heat exchanger is a critical issue to transfer
the maximum heat from the sea. Effects of the pipe diameter, wall thickness,
radius of the coil and coil pitch on the heat transfer were shown in this
paper. Moreover, friction factor of the helicoidal pipes and energy consumption
of pumps were also calculated.
