(4) Performance Evaluation Measurement A performance evaluation test was performed on the outdoor air conditioner 100 at room temperature of 35 ° C. The use side heat exchanger 3 was operated as an evaporator, and the heat source side heat exchanger 6 was operated as a condenser. The wind was blown in one direction. The blowing temperature is 22 ° C. The height of the second outlets 31a to 31d from the ground is 1.25 m. An omnidirectional probe was used as the anemometer.

When the wind was blown off at a blowing wind speed of 15.2 m / s and a blowing air flow rate of 8 m ³ / min (equivalent to 32 m ³ / min when added in four directions), the following results were obtained.

  At a distance of 1.5 m downwind from the outlet, the temperature was almost equal to room temperature. It should be noted that there was almost no change in this point even when the blowing air volume was changed. The wind speed was 0.9 m / s at a position 3 m away from the outlet and leeward from the outlet and at a height of 0.5 m from the floor.

According to the results of this experiment, if the blowing air velocity is 15.2 m / s or more, and the total blowing air volume is 32 m ³ / min or more, 0 m at the position 3 m away from the outlet and 0.5 m above the floor surface. A wind speed of 0.8 m / s or more can be realized.

(5) Features (5-1)
The outdoor air conditioner 100 of the present embodiment includes a compressor 1, a heat source side heat exchanger 6, a use side heat exchanger 3, a first fan 7, and a second fan 4 in one casing 10. . The casing 10 has a first outlet 29 and second outlets 31a to 31d. The first outlet 29 blows out the air that has passed through the heat source side heat exchanger 6 toward an upper portion outside the casing 10. The second outlets 31a to 31d are outlets disposed below the first outlet 29. The second outlets 31a to 31d blow out the air that has passed through the use-side heat exchanger 3 in a lateral direction outside the casing 10.

  The outdoor air-conditioning apparatus 100 according to the present embodiment can exhaust the air that has passed through the use-side heat exchanger 3 in a direction where a user is present and the air that has passed through the heat source-side heat exchanger 6 upward without any user.

  In the outdoor air conditioner 100 of the present embodiment, the casing 10 is formed with the second outlets 31 a to 31 d for blowing out the air that has passed through the use-side heat exchanger 3. In other words, air is blown out without passing through another flow path such as an air guide or a duct. Therefore, the air velocity, air volume, temperature, and the like of the air that has passed through the use-side heat exchanger 3 can be blown out without much change. Therefore, the air around the outdoor air conditioner 100 can be efficiently air-conditioned over a wide range.

  Further, the air-conditioning apparatus 100 of the present embodiment blows air from the second outlets 31a to 31d in the lateral direction. Therefore, the blown air can reach a range relatively far from the air conditioner 100, and air conditioning in a relatively large area is possible.

  Further, in the air-conditioning apparatus 100 of the present embodiment, the first outlet 29 blows out the air that has passed through the heat source-side heat exchanger 6 toward an upper portion outside the casing 10. Therefore, the blowout direction of the first blowout port is configured not to interfere with the lateral blowout direction of the second blowout ports 31a to 31d. This effect is particularly remarkable when the second outlets 31a to 31d blow out in all directions.

In the first embodiment, the case where the second outlets 31a to 31d are formed on all four side surfaces of the casing 10 has been described. In the outdoor air-conditioning apparatus of Modification Example 1A, the second outlet is not formed on one side surface. Others are the same as the first embodiment. Even if it is outdoors, there may be cases where cooling or heating need not be performed in a specific direction. In this case, if the second outlet is not provided on one side, cooling or heating can be performed more efficiently on the other side. Further, the configuration may be such that the second outlet is not provided on the two side surfaces.

(6-2) Modification 1B
The outdoor air-conditioning apparatus 100 according to the first embodiment has a rectangular parallelepiped shape. The outdoor air-conditioning apparatus 100 according to Modification 1B has a cylindrical shape. Others are basically the same as the first embodiment. That is, the top view of the outdoor air conditioner 100 is substantially circular. In this case, the side surface of the outdoor air conditioner 100 is one curved surface. Two or more second outlets are formed in different directions in a top view. The second outlet may be formed over substantially the entire circumference of the circle. The top view of the outdoor air conditioner 100 may be elliptical.

(6-3) Modification 1C
In the outdoor air-conditioning apparatus 100 of the first embodiment, the use-side heat exchangers 3 are arranged on four surfaces of the casing 10. In the outdoor air-conditioning apparatus 100 according to Modification 1C, the use-side heat exchangers 3 are arranged only on three side surfaces of the casing 10. The second outlet of the use side heat exchanger 3, its inlet, the heat source side heat exchanger 6, and its inlet are formed or arranged only on the same three side surfaces. Others are the same as the first embodiment.

  The outdoor air-conditioning apparatus 100 of Modification Example 1C can reduce the cost by adopting such a configuration. Further, even when the air conditioner is placed outdoors, for example, when the air conditioner is arranged near a wall, there is no useless configuration in the heat exchanger.

  The outdoor air-conditioning apparatus 100 of Modification Example 1C is formed on three sides, but the same applies to two sides.

  In the modification 1C, the use side heat exchanger 3, its outlet, its inlet, the heat source side heat exchanger 6, and its inlet are arranged or formed only on the same three side surfaces. Although the description has been given of the case where the three sides are provided, the three sides may not be configured. For example, if only the use side heat exchanger 3 has three sides, the cost can be reduced accordingly.

(6-4) Modification 1D
In the first embodiment, the heat source side heat exchanger 6 is disposed on the use side heat exchanger 3. In the case of Modification 1D, the heat source side heat exchanger 6 is arranged below the use side heat exchanger 3. However, the positions of the first outlet 29 and the second outlets 31a to 31d are not changed from those of the first embodiment.

(7-1) Overall Configuration The configuration of the refrigerant circuit of the outdoor air-conditioning apparatus 101 of the second embodiment, the configuration of the casing 10 and the components inside the casing 10 are the same as those of the outdoor air-conditioning apparatus 100 of the first embodiment shown in FIGS. , 3B. The difference is mainly in the configuration of the outlet member 30 arranged in the outlets 31a to 31d. A detailed description will be given below mainly of points different from the first embodiment.

(7-2) Detailed configuration around the outlets 31a to 31d on the use-side heat exchanger 3 side In the present embodiment, the outlet members 30 are arranged at the outlets 31a to 31d. The outlet member 30 has a frame 25, a panel 300, and a flap unit 40.

  The frame 25 is a metal plate having the shape shown in FIG. 7C. The frame 25 is attached to the columns 11a to 11d. The frame 25 has four holes corresponding to the four side surfaces 20a to 20d. The frame 25 has a first component 25a and a second component 25b that form two holes. Four panels 300 are attached to the holes of the frame 25, respectively.

  Panel 300 is made of resin. As shown in FIG. 7A, one panel 300 has four holes 301 formed therein. The flap units 40 are attached to the holes 301, respectively.

  The surface of the panel 300 or the flap unit 40 may be subjected to a weather resistance treatment. Here, examples of the weather resistant material include an acrylonitrile styrene polymer, but are not limited thereto.

  As shown in FIG. 7B, the flap unit 40 has a first flap 401, a second flap 402, and a wind direction adjustment knob 403. Air is blown out from a gap between the flaps 401 and 402 of the flap unit 40 or a gap between the flaps 401 and 402 and a frame around the flap. The flap unit 40 is made of resin. It may be made of metal. The first flap 401 is arranged outside the second flap 402. The first flap 401 can change the air blowing direction in the horizontal direction. The second flap 402 can change the air blowing direction in the vertical direction. In the present embodiment, the plurality of first flaps 401 belonging to the same flap unit 40 are designed to face in the same direction. The same applies to the second flap 402. By moving the wind direction adjustment knob 403 up and down, the inclination of the second flap 402 can be changed, and the wind direction can be changed up and down. By moving the wind direction adjustment knob 403 left and right, the inclination of the first flap 401 can be changed, and the wind direction can be changed left and right. By moving the wind direction adjustment knob 403, the outlet can be closed. In the present embodiment, four flap units 40 are arranged on each of four side surfaces 20a to 20d. Each flap unit 40 can adjust and close the wind direction by independently moving the wind direction adjustment knob 403.

  The orientation of the flaps 401 and 402 may be manually controlled as in the present embodiment, or may be automatically controlled. In order to manually operate the flaps 401 and 402, the wind direction adjustment knob 403 needs to be accessible from outside. Therefore, for example, a portion of the decorative plate that is in contact with the front surface of the wind direction adjusting knob 403 may be perforated. The decorative panel may be removable or open. As an example of the automatic control, the direction of the wind blown from a certain side surface may be changed according to time. Alternatively, blowing from a blowing port from a certain side may be sealed by a user's switch operation.

  The outdoor air conditioner of the second embodiment also has all the features described in (5-1) to (5-11) of the first embodiment.

  While the embodiments of the present disclosure have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the present disclosure described in the claims. .
