Claims

[Scope of utility model registration request]

A multi-unit system consisting of one outdoor unit 1 equipped with a compressor 3 having a drive source 17 whose rotation speed is controlled in response to load fluctuations, and a plurality of indoor units 2, 2, etc. that can be operated in parallel. In a room air conditioner, a rotation speed calculation means 22 calculates and outputs the rotation speed of the drive source 17 in response to the output of a load detection means 21 that detects the load of the entire system, and a predetermined time measured by a timer 24. The rotation speed change calculation means 25 calculates and outputs the change value of the rotation speed at , and the surplus air conditioning capacity is calculated from the maximum rotation speed of the drive source 17 output from the rotation speed calculation means 22 and the output of the rotation speed change calculation means 25. A surplus capacity calculation means 26 calculates and outputs the load of each indoor unit 2, and when there is an operation request from each indoor unit 2, it calculates the load setting value corresponding to the indoor unit 2 that has received the operation request. Indoor load setting means 30 that outputs, comparison means 31 that outputs a control signal if the surplus air conditioning capacity is equal to or higher than the load setting value, and input of the control signal of the comparison means 31 and the operation request signal of each indoor unit 2. A multi-room air conditioner characterized in that an operation control means 32 for outputting an operation command signal to each indoor unit 2 is attached.
