Air conditioning equipment operation system and air conditioning equipment designing support system

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.

An air conditioning equipment designing support system for supporting designing of a number of air conditioners provided in air conditioning equipment, comprising a step (A) of generating an annular cooling load fluctuation pattern of the air conditioning equipment;

• a step (B) of calculating initial costs by referring to a device information database storing device characteristics and prices of the number of air conditioners;
• a step (C) of calculating annual running costs from the annual cooling load fluctuation pattern by referring to the database storing the device characteristics and the prices, and a database storing fuel and electricity rates;
• a step (D) of calculating costs including device taxes and interest rates;
• and a step (E) of calculating total costs including the initial costs, and running costs of a set number of years, wherein the steps (B) to (E) are repeated changing the configuration of the air conditioners of the air conditioning equipment to set each air conditioner of the air conditioning equipment in such a way as to minimize the total costs.
