わらず、゛冷風、、を感しることになり、極めて不快に
なる。Conventional cooling/heating/rough air conditioners cannot control the capacity, so the indoor discharge air temperature does not drop during heating operation. Depending on the temperature, the heating capacity may go into a save state, and with the same air volume as in the high capacity state, the discharge air temperature may become low. That is, your body temperature may drop below 37 degrees Celsius, and even though you are in heating save mode, you will feel cold air, which will be extremely uncomfortable.

FIG. 1 is a system diagram of the present invention. ■ is a control circuit, 2 is a compressor drive circuit, 3 is a fan motor drive circuit, 4 is a capacity control compressor, 5 is an outdoor heat exchanger, 6 is an outdoor fan, 7 is a wringer, only + Hiroyasu 116 11 is the blown air temperature sensor. Thin lines indicate the control signal or power supply direction, and thick lines indicate the coolant flow path. Moreover, FIG. 2 shows the relationship between the blown air temperature and the indoor fan rotation speed. Next, the operation of this embodiment will be briefly explained. Based on the difference between the indoor temperature detected by the indoor temperature sensor 10 and the set temperature set by the customer, the compressor rotation speed is determined by the control circuit (2), and is transmitted to the compressor drive circuit (2) to perform capacity control compression. The machine 4 is driven at a predetermined rotation speed. If the rotational speed of the compressor 4 decreases, the temperature of the indoor heat exchanger 8 decreases, and as shown in FIG. 2, the blown air temperature T also decreases. The temperature of the blown air is Tym
When the temperature drops to lh, the outlet air temperature sensor, 11
Based on the temperature detected by the control circuit 1, the control circuit 1 instructs the fan motor drive circuit to reduce the fan rotation speed. As the fan rotation speed decreases, even if the compressor rotation speed remains the same, the blown air temperature, T1, increases as shown in Figure 2, but when it reaches T, the fan rotation speed is increased. Δ[0 is maintained for a certain period of time without being lowered. After that, follow the same procedure to increase the fan rotation speed. By controlling in this way, the blown air 11
