For example, when a stop signal is output from the remote control unit, the air conditioner receives the stop signal and the air conditioner transmits the stop signal to the heat exchange ventilator. Then, the air conditioner and the heat exchange ventilator are stopped at the same time.

However, when there is a problem in transmitting and receiving signals between the air conditioner and the heat exchange ventilator, or when the number of air conditioners is large, a stop signal reaches the heat exchange ventilator from the air conditioner. It takes time, and the heat exchange ventilator may stop after the air conditioner has stopped first.
In such a case, the following problems occur.

That is, when the heat exchange ventilator is driven even though the air conditioner is stopped, FIG.
As shown in FIG. 5, as a result of the supply of air from the heat exchange ventilator V entering the indoor unit 3 that is not operating, air is passed through the suction port 10 due to the air resistance in the heat exchanger 7. Is blown into the room R1 and dust adhering to a filter (not shown) or the like falls into the room R1 to give a user a discomfort.

In view of the above, it is an object of the present invention to provide an air conditioner which can prevent dust from falling when stopped.

Includes a microcomputer having a CPU, a data RAM, a program ROM, and the like, and controls according to a program stored in the ROM in advance. The stop operation of the air conditioner will be described with reference to FIGS. FIG. 5 is a flowchart showing the stop operation of the air conditioner, and FIG. 5 is a flowchart showing the stop operation of the heat exchange ventilator.

As shown in FIG. 5, the control circuit 80 of the indoor unit 40 determines whether or not the operation-OFF condition of the indoor circulation fan 42 has occurred in step S1 during normal operation. Here, when a stop signal of the air conditioner is input from the remote control unit 70, the circulation fan 4
It is determined that the operation of No. 2 should be turned off, and the process proceeds to step S2. On the other hand, when it is determined that the operation OFF condition of the circulation fan 42 has not occurred, the operation is continued.

When the process goes to step S2, a fan OFF signal is transmitted to the heat exchange ventilator V, and the process goes to step S3. In step S3, it is determined whether or not the system is a duct direct connection system based on the initialization signal at the time of system construction. If it is determined that the system is the duct direct connection system, the process proceeds to step S4. On the other hand, when it is determined that the system is not the duct direct connection system, the process proceeds to step S6, and the circulation fan 42 is actually turned off.

When the process proceeds to step S4, the residual operation of the circulation fan 42 for one minute is started, and the process proceeds to step S5. Regarding the remaining operating time of the circulation fan 42,
Maximum transmission delay time when the number of systems is maximum 1
Therefore, it is determined based on the condition that the time from when normal transmission cannot be performed until the transmission abnormality is finally determined and the fan of the heat exchange ventilator V is stopped is 1 minute.

After the lapse of minutes, the process proceeds to step S11, the fan motors FM1 and FM2 are actually turned off, and the air supply fan 31 and the exhaust fan 32 are stopped.

If the fan OFF signal is received from the control circuit 80 in step S8, the process proceeds to step S9. On the other hand, if the fan OFF signal is not received from the control circuit 80, the operation is continued. When the process proceeds to step S9, it is determined whether or not the system is the duct direct connection system based on the initialization signal at the time of system construction. If it is determined that the system is a duct direct connection system, the process proceeds to step S11, and the air supply fan 31 and the exhaust fan 32 are actually turned on.

In this way, when the indoor unit 40 determines that the circulation fan 42 of the indoor unit 40 should be stopped based on the stop signal from the remote control unit 70, it outputs a fan OFF signal to the heat exchange ventilator V. Since the residual operation of the circulation fan 42 for one minute is started, the circulation fan 42 is always stopped after the supply fan 31 and the exhaust fan 32 of the heat exchange ventilator V are stopped.

Therefore, the circulation fan 42 of the indoor unit 40
However, the air supply fan 31 and the exhaust fan 32 of the heat exchange ventilator V are not driven even though the heat exchange ventilator V is stopped. The air supply from V never comes in. Therefore, due to the air resistance in the heat exchanger 41 of the indoor unit 40, it is possible to prevent the air from blowing into the room R2 through the suction port 45a and the dust adhering to the filter 43 from falling into the room R1.

The process proceeds to 2 and it is determined whether a fan OFF signal is received from any of the air conditioners A1, A2, A3. on the other hand,
If the signal is not normally received, the process proceeds to step S4. In step S4, if one minute has passed, the process proceeds to step 5, and the air supply fan and the exhaust fan are actually turned off.

In step S2, if the fan OFF signal is received from any of the air conditioners A1, A2, A3, the process proceeds to step S3. On the other hand, if the fan OFF signal is not received from the control circuit 80, the operation is continued. When the process proceeds to step S3, it is determined whether or not the system is the duct direct connection system based on the initialization signal at the time of system construction. When it is determined that the system is the duct direct connection system, the process proceeds to step S5, and the air supply fan and the exhaust fan are actually turned off. On the other hand, if it is determined that the system is not the duct direct connection system, the operation is continued.
