Radchenko M. Increasing the efficiency of heat- and cold consumption on ships

The dissertation is devoted to creation of theoretical base for designing of high efficiency heat- and cold consumption contours. The methodological principles following from the regularities for influence of heat-mass transfer processes at the phase change final stage of heating or cooling working medium flowing inside channels and non-equal distribution of heated (cold) medium mass-flows upon ship heat exchangers efficiency were put into the base of this. The decrease in 20...30 % in heat exchangers efficiency because of non-equal air streams distribution was revealed. Increasing the heat flux in 20...40 % (heat- and cold consumption) and refrigeration coefficient in 10...20 % (cold consumption) by excluding the final stage of phase change was proved. The scheme-construction decisions of heat- and cold consumption contours developed have found design, ship and industrial applications.
