ABSTRACT:
In an air-conditioning system controller provided with a central control unit and a local control unit, the central control unit includes a heat source machine measurement system for measuring an input/output state of a heat source machine, a setting unit for setting air-conditioning condition data on air-conditioning object spaces, an outdoor air measurement system for measuring outdoor air condition data, a total air-conditioning load operating unit, an optimal operating state estimation unit, and a heat source machine control. The total air-conditioning load operating unit calculates a total air-conditioning load or a heat exchange rate of the heat source machine based on chilled water inlet and outlet temperatures and chilled water flow rate of the heat source machine.
