An air conditioning equipment operation system in which air conditioning equipment provided in a contract site is operated by a service provider company, wherein the service provider company has a control server, said system comprising a device information database storing a device characteristic data of an air conditioner constituting the air conditioning equipment, a fuel or electricity rate database storing rate data of at least one of gas, oil and electric power, and an air conditioning equipment simulator for obtaining a partial load factor, and at least one of power consumption and fuel consumption during partial load running by using the device characteristic data and a cycle simulator, and for calculating running costs from the obtained power consumption and/or fuel consumption by using the rate data, wherein the contract site includes an air conditioning equipment management controller provided to manage and control the air conditioning equipment;

  • the control server and the air conditioning equipment management controller are connected to each other through a network;

    the control server predicts a cooling load from predictable time series data on a temperature and humidity of outside air by referring to the device information database to make an operation plan of the air conditioner; and

    the air conditioning equipment management controller operates the air conditioner in accordance with the operation plan; and

    wherein the air conditioning equipment simulator calculates running costs for each operation of the air conditioner, and makes operation plan data by an operation method having lowest running costs among the calculated running costs.
