となる。 To explain the operation of the device configured as described above, first, during heating, when heating is performed by heating the room when the indoor temperature is low as in the early stage of heating (hereinafter referred to as heating), this is detected by the temperature detection element 25. It is detected, the solenoid valve 16 is turned on and opened, the burner 23 is burned, and the solenoid valve 22 is also turned on and opened.
Further, the wind direction plates 13 and 14 are moved so that the discharge direction is downward. As a result, the refrigerant is heated by the refrigerant heater 17 and evaporated to become a high-temperature, high-pressure gas refrigerant, as shown by the broken line, and is sucked into the compressor 18 and discharged.
It passes through the bypass circuit 21 to the second heat exchanger 8 and further passes through the solenoid valve 16 to the first heat exchanger 7 and returns to the refrigerant heater 17. At this time, the first and second heat exchangers 7 and 8 are heated and the blower 9 is operated to exchange heat and heat the room, but the indoor temperature distribution at this time is the same as in the conventional case, as shown in Figure 1. However, when the temperature in the upper part of the room rises to a predetermined temperature, the temperature detection element 25 detects this, and the heat utilization operation (in which the heat in the heated upper part of the room is used to heat the lower part of the room) (hereinafter referred to as heat utilization operation). That is, when the temperature in the upper part of the room reaches a predetermined temperature, the temperature sensing element 25 activates the solenoid valve 16.
is turned off and blocked, combustion of burner 23 is stopped,
In addition, while leaving only the side of the wind direction plate 14 as it is, the wind direction plate 14 is moved so that the air is discharged upward into the room.
As a result, the refrigerant flows as shown by the dashed line,
Since the throttle resistor 15 is interposed, the second heat exchanger 8 acts as a condenser, and the first heat exchanger 7 acts as an evaporator. The refrigerant passing through the first heat exchanger 7 is
Bypass circuit 2 from refrigerant heater 17 and compressor 18
1 and reaches the second heat exchanger 8. At this time, by operating the blower 9, one side of the air from the common blades 10 is cooled through the first heat exchanger 7 and discharged upward into the room, and the other side is sent to the second heat exchanger 8.
The gas is heated and discharged downward into the chamber. As a result, the temperature distribution in the room is almost uniform as shown in Figure 4, and the amount of heat from the temperature difference (shaded area in the diagram) compared to the conventional one is used effectively, eliminating discomfort in the living space and saving energy. It also becomes. On the other hand, during cooling, the solenoid valve 16 is turned on and opened, and the burner 23
The combustion is turned off, and the solenoid valve 22 is turned off and closed. Further, both of the wind direction plates 13 and 14 are moved so that the discharge direction is upward in the room. As a result, the refrigerant is transferred to the compressor 18, the outdoor heat exchanger 19, the throttle resistor 20, the second heat exchanger 8, the solenoid valve 16, the first heat exchanger 7, and the refrigerant heater 1, as shown by the solid line.
7 and returns to the compressor 18. At this time, the outdoor heat exchanger 19 acts as a condenser, and the first and second heat exchangers 7 and 8 act as evaporators.
By operating the blower 9 to blow air,
The air is cooled and discharged upward into the room to cool the room. In this way, since the blades 10 of the blower 9 and the electric motor 11 are commonly used, the cost becomes low.

から安価に製作できる効果がある。 As explained above, this invention includes an outer casing, a first ventilation passage and a second ventilation passage formed in the outer casing, and a first heat exchanger provided in the first ventilation passage and functioning as an evaporator of a heat pump. an exchanger and the second
a second heat exchanger that is provided in the ventilation passage and is connected to the first heat exchanger and acts as a condenser of the heat pump; and a common heat exchanger that blows air to both the first ventilation passage and the second ventilation passage. The first heat exchanger and the second heat exchanger are connected through a throttle resistor and a solenoid valve installed in parallel with the fan, and during heating operation, the blower is installed in the upper part of the room. By controlling the opening and closing of the solenoid valve using the detection output of the installed temperature detection element, the heat in the upper part of the room heated by the heater is effectively used to cool the upper part of the room and heat the lower part of the room. Since the indoor temperature can be made uniform, it is possible to obtain an indoor unit of an air conditioner that is comfortable and has little heat loss, and because the blades are common, it can be manufactured at low cost.
