| Abstract: | In order to evaluate the energy-saving effect of seawater source heat pump units over conventional water cooled chillers precisely,various factors that affect the energy consumption of chillers are analyzed.Then a mathematical model of optimal chiller loading was set up on the basis of dynamic programming theory.Through a case study of an office building,the steps of optimal selection of heat pumps or chillers with different capacities are brought out based on the principle that the total energy consumption throughout the cooling season is minimized.And the energy-saving of the seawater source heat pump units in the case project is calculated to be 16.3%.The energy-saving evaluation method of seawater source heat pump units provided in the paper can minimize the calculation error as it is based on the optimal selection of different heat pumps or chillers. |
