  • the controller 46 provides a drive signal to change the dampers 32, 33 for the exhaust switched mode. Then, the controller goes to STEP 12.
  • the controller 46 provides a signal to the first fan 31 for running at the number of revolutions corresponding to the instructed amount of airflow. Consequently, the first fan unit 21 performs the exhaust mode. Then, the controller goes to STEP 13.
  • the controller 46 provides a signal to the second fan unit 22 for running at the number of revolutions corresponding to the instructed amount of airflow, and returns to STEP 1. Then, the state is maintained until the remote controller 49 is operated again and the ventilation mode is changed.
  • the condition of the air pollution detected by the CO2 sensor 47 or the gas sensor 48 is fed to the controller 46, which then goes to STEP 22.
  • the controller 46 compares the condition of the air pollution with predetermined high and middle settings to determine whether the condition of the air pollution is high state, middle state or low state. The controller goes to STEP 23 if high state, STEP 24 if middle state, and STEP 25 if low state.
  • the controller 46 executes the above STEPS 11-13 to perform the double exhaust mode, and then returns to STEP 21 to maintain the present state until the condition of the air pollution will be under the high state.
  • the controller 46 executes the above STEPS 8-10 to perform the single exhaust mode, and then returns to STEP 21 to maintain the present state until the condition of the air pollution will be under the middle state.
  • the controller 46 provides a halt signal to the fan units 21, 22 to halt the fan units 21, 22 and then returns to STEP 21 to maintain the halt state until the condition of the air pollution will be over the low state.
  • the controller allows the double exhaust mode if the condition of the air pollution is high state, and allows the single exhaust mode if middle state, but halts the exhaust mode if low state.
  • the controller as the control means, having following controls: 1) when air-supply/exhaust operation signal is made, the first fan unit is changed to air-supply mode, and the exhaust mode of the second fan unit will be started; 2) when the signal of air-supply mode is made, the first fan unit is changed to air-supply mode; and 3) when the signal of exhaust mode is made, the second fan unit is changed to exhaust mode.
  • control means further includes means corresponding to each step to be executed, which is operative to execute each step. It is not always required to include all of the above means.
  • FIG. 11 is an operation pattern table for control of the air conditioner according to the second example.
  • Fig. 12 is a brief illustrative view of double air- supply mode.
  • those corresponding to the components of the preceding first example are denoted with the same reference numerals and omitted from the following detailed description.
  • the second fan unit 22 is the exhausting fan unit while in the second example a second fan unit 60 is provided instead of the second fan unit 22.
  • the second fan unit 60 the ventilation fan unit for taking in the air from the outside or exhausting the room air similar to the first fan unit 21 and includes a second fan 61, an inlet side damper 62, and an outlet side damper 63.
  • the second fan 61, the inlet side damper 62 and the outlet side damper 63 have the same structures and functions as those of the second fan 31, the inlet side damper 32 and the outlet side damper 33 in the first fan unit 21.
  • the second fan unit 60 is possible to perform both air-supply mode and exhaust mode. In the second example, therefore, a double air-supply mode can be performed as shown in Fig. 11.
  • the controller 46 performs the single air-supply mode if the power of airflow to be sent is middle or weak while it performs the double air-supply mode if the power of airflow is strong.
  • the following STEPS 14-16 (not shown in the figure) are added to the flow shown in Fig. 8 such that the first fan unit 21 is subjected to the air-supply mode (STEP 14) , and the dampers 62, 63 are changed to the air-supply mode (STEP 15) and the second fan 61 is run (STEP 16). Consequently, both the first fan unit 21 and the second fan unit 60 are subjected to the air-supply mode as shown in Fig. 12.
  • the second fan unit 60 is the air-supply/exhaust double-functioned fan unit, in STEPS 4, 7, 10, 13 the indication "EXHAUST-SPECIFIED UNIT” should be replaced by "AIR-SUPPLY/EXHAUST DOUBLE-FUNCTIONED UNIT” and the indication "RUN” by "ALLOW EXHAUST OPERATION OF".
  • the flow of the exhaust operation of the second fan unit 60 is same as the flow (STEPS 11, 12) of the exhaust operation of the first fan unit 21, which switches the dampers 62, 63 to the exhaust switched position and runs the second fun 61.
  • the actuation of the operating unit makes it possible to select from among the operation modes of ventilation including the air-supply/exhaust operation with simultaneous execution of both air-supply and exhaust, the air-supply operation with only air-supply and the exhaust operation with only exhaust. Therefore, the present invention is optimally applicable to air conditioners operative to ventilate while air conditioning.
