The characteristics of a heat exchanger composed of plate and tube operating with melting of piled and falling snow have been investigated theoretically and experimentally. In case of the melting of falling snow, the perfect melting condition and the melting efficiency were related to dimensionless parameters for the heat exchanger and the surrounding conditions. The calculated results for the perfect melting condition and the melting efficiency were in agreement with the results obtained from the field experiments. In case of the melting of piled snow, a quasi-state model of two dimensional snow melting was presented. The melting efficiency becomes higher with a higher inlet brine temperature for the melting of subcooled snow. The melting efficiency of piled snow is higher than that of the falling snow, because the piled snow remaining on the plate acts as an insulator during melting.
