The invention relates to a marine variable-water-volume air conditioner system which comprises a water chilling unit and a plurality of marine air conditioners, a variable-frequency cooling water pumpis arranged on a cooling water inlet pipe on one side of cooling water of the water chilling unit, one side of refrigerant water of the water chilling unit is connected with a water distributor, andthe water distributor is in liquid inlet connection with the marine air conditioners through a plurality of control valves. Liquid return of the marine air conditioners is connected to the water collector, and the water collector is connected to one side of refrigerant water of the water chilling unit through the variable-frequency refrigerant water pump in a return mode. A pressure difference sensor is connected between the water distributor and the water collector, the water distributor is communicated with the water collector through an electric control valve, and the pressure difference sensor controls the variable-frequency cooling water pump, the variable-frequency refrigerant water pump and the electric control valve through a PLC. The energy-saving effect of the system is more remarkable in a large ship air conditioning system, especially in an area with a large air conditioning area.
