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.
