Abstract
Abstract A method and apparatus for wiring/piping confirmation of a multiple air conditioner is disclosed in which a plurality of internal units is actuated manually or automatically or by remote control, a refrigerant pipe for a single internal unit is opened and the resulting change is detected by the internal unit. The changing data is returned to the controller through a serial communication wiring or together with the identification number of the internal unit by bus communication. The controller confirms the correspondence relationship between the wiring that has received the data or the identification number of the internal unit and the opened piping. This process is repeated with respect to each internal unit.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
123 words
A method of confirming wiring between a plurality of internal units and a controller provided in an external unit and piping supplies of a refrigerant to each internal unit in a multipie air conditioner system,wherein said method comprises the steps of: actuating at least one of the plurality of internal units connected to the controller; supplying the refrigerant to an internal unit by opening a refrigerant pipe connecting said internal unit and said externai unit; detecting a change in temperature produced by the refrigerant in said internal unit; transmitting data of said change in temperature to the controller from said internal unit through wiring; and detecting a correspondence relationship between said wiring transmitting said change in temperature data and said opened refrigerant pipe.
Claim 2
Independent Claim
123 words
A method of confirming wiring between a plurality of internal units and a controller provided in an external unit and piping supplies of a refrigerant to each internal unit in a multipie air conditioner system,wherein said method comprises the steps of: actuating at least one of the plurality of internal units connected to the controller; supplying the refrigerant to an internal unit by opening a refrigerant pipe connecting said internal unit and said externai unit; detecting a change in temperature produced by the refrigerant in said internal unit; transmitting data of said change in temperature to the controller from said internal unit through wiring; and detecting a correspondence relationship between said wiring transmitting said change in temperature data and said opened refrigerant pipe.
