| Bibliography: | In view of energy waste and environmental pollution in the process of ship navigation, a triple low temperature heat source for heating system is presented. It considers the advantages of solar energy heat pump and water source heat pump and waste heat utilization. This system can make high-quality heat by using the solar radiation, seawater and residual heat in marine cylinder liner cooling water. It can change the operation mode by valve switching according to the different weather conditions. The heating mode was different in different time. For Dalian area as an example, it gives out the collector outlet temperature curve by computer simulation. And it shows that the combined heat source can increase the heating coefficient by 1.03. It solves the problem of single application of solar energy or water source heat pump, making full use of the waste heat, so it is feasible for dynamic selection of ship heating mode. marine ; triple heat source ; heat pump ; residual heat ; energy saving 31-1707/T ZHOU Li-bin, C |
