Claim 15:
16. The method of claim 15, wherein the calculating of the amount of change in the total operation load of the plurality of indoor units and the controlling of the at least one refrigerant control valve further comprise:
calculating each of a first amount of change in a first operation load for an indoor unit, of the plurality of indoor units, connected to a first fluid-refrigerant heat exchanger of the plurality of fluid-refrigerant heat exchangers and a second amount of change in a second operation load for an indoor unit of the plurality of indoor units, connected to a second fluid-refrigerant heat exchanger of the plurality of fluid-refrigerant heat exchangers; and
determining an opening degree of a first refrigerant control valve of the plurality of refrigerant control valves that controls an amount of the refrigerant flowing through the first fluid-refrigerant heat exchanger, based on the first amount of change in the first operation load, and determining an opening degree of a second refrigerant control valve of the plurality of refrigerant control valves that controls an amount of the refrigerant flowing through the second fluid-refrigerant heat exchanger, based on the second amount of change in the second operation load.
