る。(Prior art) An air conditioner mainly includes an indoor unit and an outdoor unit,
These were often set. But,
In recent years, there is a tendency to use an indoor unit and an outdoor unit, each having a control unit therein, connected to each other. In this case, as the outdoor unit, the capacity of the compressor is controlled by the inverter and the "inverter heater" capable of switching between the cooling operation and the heating operation. The capacity of the compressor is controlled by the inverter, but only the cooling operation is performed. "General inverter", which can switch between cooling and heating operation by controlling on / off of the compressor, "general cooling", which only performs cooling operation by controlling on / off of the compressor, etc. There are various types. On the other hand, the control unit of the indoor unit and the control unit of the outdoor unit are both configured by microcomputers, and perform operation control by transmitting and receiving signals between them, but unless different control signals are used according to the type of the outdoor unit. May not be. Then, the control unit of the indoor unit transmits a model identification signal to the control unit of the outdoor unit, and returns the model signal to the control unit of the outdoor unit to determine the type of the outdoor unit. Is to be sent.

して以下にこの空気調和装置の動作を説明する。FIG. 2 is a schematic configuration diagram of a conventional air conditioner of this type, in which an indoor unit 1 having a control unit 4 and an outdoor unit 2 having a control unit 5 are connected by a crossover 3, and 1 is connected to a remote control device 6. Here, the crossover 3 has a power supply voltage supply and a control signal transmission / reception.
The remote controller 6 outputs an operation command, a stop command, etc., and sets the temperature.
The control unit 4 receives signals of control input elements such as a room temperature sensor and a heat exchange sensor, and controls controlled elements such as an indoor fan and a heater. The control unit 5 of the outdoor unit also has a heat exchange sensor and a compressor thermostat. And the like to control the controlled elements such as the outdoor fan and the four-way valve. However, since these are not directly related to the present invention, the description thereof is omitted, and mainly the relationship of signal exchange performed between the control unit 4 of the outdoor unit 1 and the control unit 5 of the outdoor unit 2 will be mainly described. The operation of the air conditioner will be described below with reference to FIG.
先ず、時刻t1にて電源が投入されたとすると、室内機
１の制御部４は、第３図に示すように、機種判別信号S1
1を送信し、これに応じて室外機２の制御部５に対して
機種信号S21を返送させることにより、いわゆる室外機
種類判別を行っている。First, when at time t 1 the power source is turned on, the control unit 4 of the indoor unit 1, as shown in FIG. 3, model determination signal S1
By transmitting 1 and returning the model signal S21 to the control unit 5 of the outdoor unit 2 in response to this, the so-called outdoor unit type determination is performed.

運転を続行する。Next, at time t 2, the When operation command from the remote control device 6 is provided, the control unit 4 together with to start operation of the indoor unit 1, and transmits the operation command to the control unit 5. In response, the control unit 5 starts the operation of the outdoor unit. Then, based on a signal from the remote control device 6 or a control input element in the room,
When the control unit 4 transmits the operation control command S12 to the control unit 5,
The control unit 5 controls the outdoor unit 2 in response to this, and continues the operation in the procedure of returning the operation state signal S22 to the control unit 4.
次に、時刻t3にてリモコン装置６から停止指令が与え
られたとすると、制御部４は室内機１の運転を停止させ
ると共に、制御部５に停止指令を送信する。これに応じ
て制御部５は室外機の運転を停止させる。Next, when a stop command from the remote control device 6 at time t 3 is given, the control unit 4 stops the operation of the indoor unit 1, and transmits a stop command to the control unit 5. In response to this, the control unit 5 stops the operation of the outdoor unit.
以下、電源が投入されている限り、リモコン装置６の
信号に基づいて制御部４と制御部５とが同様な動作を繰
返す。Hereinafter, as long as the power is turned on, the control unit 4 and the control unit 5 repeat the same operation based on the signal of the remote control device 6.

問題であった。(Problems to be Solved by the Invention) In the above-mentioned conventional air conditioner, the outdoor unit type determination is performed only when the power is turned on. If a model signal from the control unit 5 is erroneously received due to the occurrence of sag or noise,
Thereafter, the operation control is performed with the model of the outdoor unit being erroneously recognized until the power is turned on again, so that appropriate operation control cannot be performed. This has been a particularly serious problem in a commercial air conditioner in which power is hardly re-input.

するものである。(Means for Solving the Problems) In the control method for an air conditioner according to the present invention, when the remote controller outputs an operation command, the control unit of the indoor unit starts the operation of the indoor unit and controls the outdoor unit. When the unit starts the operation of the outdoor unit and the remote control device outputs a stop command, the control unit of the indoor unit stops the operation of the indoor unit,
The air conditioner in which the control unit of the outdoor unit stops the operation of the outdoor unit is applied.When the power is turned on and when the remote control device outputs the stop command, the control unit of the indoor unit controls the outdoor unit. The type of the outdoor unit is transmitted to the control unit of the outdoor unit in response to the type determination signal, and the type of the outdoor unit is returned to the control unit of the outdoor unit in response to the type determination signal.

If an outdoor unit type discrimination signal is added to the
The determination process becomes complicated and causes erroneous determination. However, when the air conditioner is stopped, the signal configuration and its processing are simplified only by the stop signal, and the operation is stopped thereafter, so that erroneous determination due to power sag or noise hardly occurs. Accompanying improper control operation can be eliminated at an early stage.

FIG. In the figure, when the power is turned on at time t 1, the control unit 4 transmits a model determination signal, the control unit 5 is the point of performing the outdoor unit type discrimination and return the model signal is the same as the conventional. Also,
Together with the control unit 4 when the operation command from the remote control device 6 is given to start the operation of the indoor unit 1 at time t 2, the control unit 5
Starts the operation of the outdoor unit 2, and further, when the control unit 4 transmits the operation control command S21, the control unit 5 returns an operation state signal as in the conventional case. However, if the stop command from the remote control device 6 at time t 3 is given, Again, the control unit 4 outputs a model determination signal, the control unit 5 makes a outdoor unit type discrimination and return the model signal The point that the control unit 4 stops the indoor unit 1 and the control unit 5 stops the outdoor unit 2 later is clearly different from the related art.

させることができる。As described above, if the outdoor unit type determination is performed when the stop command is received from the remote control device 6, for example, power sag when the outdoor unit type determination is performed when the power is turned on,
Even if the type of the outdoor unit is erroneously determined due to noise, the improper control operation accompanying the erroneous determination is eliminated at the time of re-operation, so that the commercial air conditioner can continue to operate with peace of mind. Thereby, the reliability of the device can be improved.

大幅に向上させることができる。As is apparent from the above description, according to the present invention, the signal configuration and processing are simpler than those in the normal control operation, and after that, the operation stop command for stopping the operation is received from the remote control device. Sometimes, the outdoor model is determined, so even if the outdoor unit type is erroneously determined due to power sag, noise, etc., the improper control operation associated with the erroneous determination is eliminated at an early stage, thereby improving the reliability of the device. Can be greatly improved.
