的に制御することによりスイング運転も可能となる。The operation of the above structure will be described. The behavior on the refrigerant side is the same as that of the first embodiment both during cooling and during heating, and therefore its description is omitted. The pressurized air blown out from the blower 3 is guided to the indoor unit 102a through the pressurized air pipes 1aa, 1ab, 1ba, 1bb, and the ejection nozzle 5a.
The air is blown from a, 5ab, 5ba, 5bb to the air outlet 4a. The blown pressurized air flows along the throttle shape of the air outlet 4a. At this time, an attracting action occurs in which the room air around the air suction port 6a is drawn toward the indoor heat exchanger 110a, and the attracting action causes the room air to be sucked in from the air suction port 6a to move inside the indoor heat exchanger 110a. It exchanges heat with the flowing refrigerant. At this time, the indoor air is cooled in the cooling operation and heated in the heating operation. After that, the indoor air that has been deprived of heat by the heat exchange action or given heat is blown out from the air outlet 4a,
Cool or heat the room. Here, for example, flow rate control valves 9aa and 9b provided in the pressurized air pipes 1aa and 1ba, respectively.
It is assumed that the valve opening of a is narrowed. At this time, the jet nozzle 5aa,
The amount of pressurized air jetted from 5ba is the jet nozzle 5ba,
Since the amount of pressurized air ejected from 5bb decreases, the amount of indoor air to be attracted is larger on the ba and bb sides than on the aa and ba sides, and as a result, the air blown out from the air outlet 4a is on the aa and ba sides. Becomes biased in the direction. By adjusting the openings of the flow rate control valves 9aa, 9ab, 9ba, 9bb in this way, the air blowing angle can be freely controlled by 360 degrees, and the flow rate control valves 9aa, 9ab can be set at a certain time interval. Swing operation is also possible by regularly controlling the valve opening degrees of 9ba, 9ba, and 9bb.

By controlling the flow rate of the pressurized air with aa, 9ab, 9ba, and 9bb to blow it out, it is possible to give directionality to the blowing of air into the room and eliminate the uneven temperature distribution in the room. In this embodiment, the flow rate control devices 9aa, 9ab, 9b
Although the flow rate control valves are used as a and 9bb, there is no particular limitation as long as the flow rate of the pressurized air can be controlled. In addition, although the ejection nozzles 5aa, 5ab, 5ba, and 5bb are symmetrically arranged in the upper and lower portions respectively, the number is not limited, and the valve opening degree of the flow control valve or the like is controlled even if the ejection nozzles are not symmetrical.

Since the cooling operation and the heating operation are basically the same as those of the first embodiment of the present invention, the description thereof will be omitted. Here, the dehumidifying operation often used in the rainy season will be described. For example, if the indoor unit 102a performs a dehumidifying operation, the refrigerant flows as in the cooling operation. The four-way valve 107 is installed on the solid line side. The high-temperature and high-pressure refrigerant discharged from the compressor 105 passes through the four-way valve 107 and flows into the outdoor heat exchanger 121,
Here, it is condensed and liquefied. After that, the electronic expansion valve 112a,
When passing through 112d, the flow rate is controlled to an appropriate value and decompressed, and one of the two flows into the indoor heat exchanger 110a, where it is heat-exchanged with the indoor air to be evaporated and vaporized. The other flows into the heat exchanger 10 for pressurized air and heat-exchanges with the pressurized air blown out from the blower 3 to evaporate and vaporize. The evaporated and evaporated refrigerant merges in the outdoor unit 101, then passes through the four-way valve 107 and is sucked into the compressor 105. The pressurized air that has been blown out from the blower 3 and has exchanged heat with the refrigerant in the pressurized air heat exchanger 10 becomes low temperature and low humidity and flows into the pressurized air pipes 1a and 1b. Since the pressurized air pipes 1a and 1b pass through the exhaust passage 11 of the outdoor heat exchanger 121, the condensed exhaust heat is collected here, and the pressurized air in the pressurized air pipes 1a and 1b is brought into a high temperature and low humidity state. Then, it is guided to the indoor unit 102a and blown out from the ejection nozzles 5a and 5b to the air outlet 4a. The blown pressurized air flows along the throttle shape of the air outlet 4a, and at this time, the air around the air inlet 6a is attracted toward the indoor heat exchanger 110a. The indoor air is sucked from the air suction port 6a, passes through the indoor heat exchanger 110a, exchanges heat with the refrigerant flowing through the indoor heat exchanger 110a, is cooled and dehumidified, and is guided to the air outlet 4a. Here, the dehumidifying operation is performed without lowering the blowout temperature by being mixed with the high temperature and low humidity pressurized air. When executing other operation patterns, the operation control of the electronic expansion valves 112a, 112b, 112c, 112d and the solenoid valves 2a, 2b, 2c, 2d, 2e, 2f may be performed as in the first embodiment.

Part of the high-temperature and high-pressure refrigerant discharged from 5 is the bypass pipe 1.
It flows into 9. Since the bypass pipe 19 is arranged in heat exchange with the heat medium 12, the refrigerant flowing into the bypass pipe 19 exchanges heat with the heat medium 12 and is cooled, and then guided to the suction pipe 18 and returned to the compressor 105. Be done. The heat medium 12 that has exchanged heat with the refrigerant is given heat, and thermally expands in the container 13 until the pressure becomes equal to that of the discharged refrigerant. Here, when a predetermined pressure difference occurs before and after the pressure member 15, that is, on the heat medium side and the air side, the restoring force of the coil spring 16 is exceeded, and the pressure member 15 moves the inside of the connecting pipe 14 to the air side.

Further, since the bypass pipe 19 is arranged so as to exchange heat with the heat medium 12, the heat medium 12 performs the heat contraction action until the pressure becomes equal to that of the suction refrigerant.
Then, the pressure difference before and after the pressure member 15 decreases, and when the pressure difference is within a predetermined value, the restoring force of the coil spring 16 exceeds the pressure difference before and after the pressure member 15, and the pressure member 15 reaches a certain fixed position. Will be returned. By performing the intermittent operation of the two-way valve 20 in this manner, the pressurized air pipes 1a, 1b, 1c, 1d, 1
By sending air to e and 1f, it becomes possible to cool and heat the room.

The member 15 reciprocates to move the indoor units 102a, 102b,
Since the pressurized air is blown to 102c, the energy consumption of the pressurized air producing means 3 is reduced and the operating efficiency can be improved. In this embodiment, a two-way valve is used as an example of the bypass opening / closing means 20, but an electromagnetic valve, an opening / closing valve or the like may be used as long as the opening / closing operation can be performed intermittently. Further, the heating medium 12 may be any one that can easily change the pressure with a slight temperature change, such as CFC, ammonia, and water. Further, although the discharged refrigerant is used as the heating source 19, any material that intermittently heats the heating medium 12 may be used, such as a heater,
You may use warm water, solar heat, equipment waste heat, etc.
