The housing 21 has a side surface and an upper surface, the side surface is formed in a cylindrical shape, and the upper surface is formed in a curved shape so as to bulge upward. On the side surface of the housing 21, a first intake port 22 is formed on the upper side, and a second intake port 23 is formed on the lower side. An outlet 24 is formed on the side surface of the housing 21 at a position opposite to the positions of the first and second intake ports 22 and 23. A heat exhaust port 25 is formed on the upper surface of the housing 21.

As shown in FIG. 3, inside the housing 21 of the main body 11, the battery (first power source) 31, the compressor 32, and the compressor 32 and the compressor 32 are provided in the lowermost part from the second intake port 23 side toward the outlet port 24 side. The 1st tank 33 is provided, the 1st fan 34 and the 1st heat exchanger 35 are provided in the center part of an up-down direction, and the 2nd heat exchanger 36 is provided in the uppermost part. Of these, the compressor 32, the first fan 34, the first heat exchanger 35, and the second heat exchanger 36 are included in a refrigeration cycle unit 61 described later. The first heat exchanger 35 operates as an evaporator during the cooling operation of the main body 11 and as a condenser during the heating operation of the main body 11. On the other hand, the second heat exchanger 36 operates as a condenser during the cooling operation and as an evaporator during the heating operation.

Here, the first intake port 22 is an opening that takes in outside air for blowing air to the second heat exchanger 36. The second intake port 23 is an opening that takes in outside air for blowing air to the first heat exchanger 35. The outlet 24 is an opening for blowing out cool air or warm air generated by the air conditioning operation in the main body 11. The heat exhaust port 25 is an opening for discharging heat generated by the air conditioning operation in the main body 11.

In the second heat exchanger 36, the refrigerant is liquefied when it is cooled by sending the air sucked from the first intake port 22 by the second fan 63 toward the second heat exchanger 36. The air that has passed through the second heat exchanger 36 is discharged from the heat exhaust port 25 in a state that it contains the heat that is released by the liquefaction of the refrigerant in the second heat exchanger 36.

The refrigerant liquefied in the second heat exchanger 36 is sent to the expansion valve 64 and injected into the first heat exchanger 35 through the minute nozzle holes of the expansion valve 64 to be vaporized at a dash. The vaporized refrigerant removes heat around the first heat exchanger 35, whereby the first heat exchanger 35 is cooled. The air taken in from the second intake port 23 by the first fan 34 is cooled by passing through the first heat exchanger 35. The cooled air is blown out as cold air from the outlet 24. On the other hand, the refrigerant exiting the first heat exchanger 35 returns to the compressor 32 and is compressed again.

In the heating operation of the refrigeration cycle unit 61, as shown in FIG. 6, the high-temperature and high-pressure refrigerant compressed by the compressor 32 is sent to the first heat exchanger 35 via the four-way valve 62. In the first heat exchanger 35, the refrigerant is liquefied when it is cooled by sending the air sucked from the second intake port 23 by the first fan 34 toward the first heat exchanger 35. The air that has passed through the first heat exchanger 35 is in a state that it contains the heat that is released by the liquefaction of the refrigerant in the first heat exchanger 35, and is blown out as warm air from the outlet 14.

The refrigerant liquefied in the first heat exchanger 35 is sent to the expansion valve 64, and is injected into the second heat exchanger 36 through the minute nozzle holes of the expansion valve 64 to be vaporized at once. The vaporized refrigerant removes heat around the second heat exchanger 36, so that the second heat exchanger 36 is cooled. The air taken in by the second fan 63 from the first intake port 22 is cooled by passing through the second heat exchanger 36. The cooled air is discharged from the heat exhaust port 25. On the other hand, the refrigerant exiting the second heat exchanger 36 returns to the compressor 32 and is compressed again.
