It will not be possible to achieve its original performance, and operation outside the operating air volume range will result in equipment damage and reduced reliability. Also, even when checking by driving, the damper opening/closing means is thermo-O.
In the case of installing a duct-type air conditioner, the sensor for temperature control in each air area is closed. The installation is also carried out on-site, and there is also the problem of discovering incorrect connections, disconnections, etc. after actually driving the vehicle. An opening/closing unit room setting means for setting correspondence between a plurality of corresponding damper opening/closing means and a plurality of air conditioning areas; and an installation position confirmation control means that opens and closes the damper opening/closing means for a certain period of time in a predetermined order when installation position confirmation is input. A sensor connection determination device for determining the connection of temperature control sensors in a plurality of air conditioning areas; and a sensor connection determination device that determines the connection of temperature control sensors in a plurality of air conditioning areas; Use room determination means that compares the input of the opening/closing section room setting means that sets correspondence with multiple air conditioning areas.
The apparatus is characterized by comprising a warning means that warns when the result of the used room determination means is abnormal.The correspondence between the plurality of dampers and the plurality of air conditioning areas is set by the operation opening/closing part room setting means.When inputting the installation position confirmation The dampers are opened and closed at regular intervals in a predetermined order in the air-blowing state, and air is sent to multiple air-conditioning areas sequentially.Also, it is possible to deal with disconnected temperature control sensors in multiple air-conditioning areas, and how to deal with multiple dampers and multiple air-conditioning areas. Compare with the room used by the opening/closing room setting means to set l, x,
The connection state between the air conditioning area set by the opening/closing room setting means and the sensor is determined, and a warning is issued in case of an abnormality.Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. FIG. 3 is a block diagram and a flowchart of the operation control device for a duct type air conditioner according to the first embodiment of the present invention. Operation control means 5. The opening/closing room setting means 6 is the same as the conventional block diagram. 7 is the installation position confirmation control means;
Although it is activated by the installation position confirmation input (for example, when the switch is initially turned on), room A is set to the damper 3a by the opening/closing room setting means 6 in Fig. 2! , :, damper 3cK for room 13,
If chamber C is set to damper 3b, the fan will be set to 0NLA from damper 3a to 3b by the installation position confirmation input.
, 3c, and so on at regular intervals. The air is blown in the order of room A, room C, and room B corresponding to each damper. In the second embodiment of the present invention, a block circuit diagram and a flowchart of an operation control device for a ducted air conditioner are shown. In FIG. Reference numeral 10 denotes a warning means.Used room determination means 9 (Y) Compares and makes a determination between the setting state of the opening/closing section room setting means 6 and the result of the sensor connection determination means 8.In FIG. If the voltage level on the positive side is set by the comparator 8a to be lower than the potential on one side in the normal use area of the sensor 11, the output of the comparator 8a will be L in the normal use area of the sensor.If the sensor is not connected, the output of the comparator 8a will be L. H output and flowchart in Figure 6 Steps 1 to 3C
The correspondence between the damper and the air conditioning area is confirmed by the opening/closing room setting means 6. Step 4 is branching based on the result of the sensor connection determining means 8, and steps 5 to 7 are the opening/closing room setting means when the sensor is connected or not connected. 6.

Effects of the Invention According to the duct type air conditioner of the present invention, correspondence between multiple dampers and multiple air conditioning areas is set by the opening/closing room setting means, and the installation position is confirmed. At the time of input, the installation position confirmation control means opens and closes the damper at regular intervals in a predetermined order, and blows air to multiple air conditioning areas sequentially. Since the operation involves thermo-operation, it can be easily determined regardless of the installation factory date, making it a simple method for construction.To prevent mistakes, it is possible to prevent equipment damage and reliability due to operation outside the operating air volume range when incorrect settings are made. Although it is possible to prevent the deterioration from occurring, it is also possible to compare and judge the results of the sensor connection determination means and the opening/closing room setting means.
Warnings can be issued in the event of an abnormality, such as unconnected sensors, incorrect wiring if there is an unused damper, or incorrect setting of the opening/closing room setting. Although it is possible to prevent mistakes,
