(Embodiment 1)
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a schematic side sectional view showing a configuration example of the air conditioner 1 according to the first embodiment. FIG. 2 is a perspective view showing the appearance of the air conditioner 1. The air conditioner 1 is provided with a box-shaped housing 15, and is placed on the floor surface of an air-conditioned space such as a factory by means of casters 151 provided at the bottom of the housing 15. The mounted state of the air conditioner 1 shown in FIG. 1 is shown vertically and horizontally as a normal usage mode of the air conditioner 1. Note that FIG. 1 is a schematic view of a cross section taken along the line AA in FIG. 2 from the left side on FIG.

The air conditioner 1 includes a heat exchanger 2 and a spraying unit 16, and uses the heat of vaporization of the sprayed water sprayed from the spraying unit 16 to lower the atmospheric temperature and cool the air-conditioned space. For example, indirect vaporization. It is a cooling type air conditioner 1.

The housing 15 of the air conditioner 1 is provided via a suction port 51 for sucking air in the air-conditioned space, a first outlet 31 for blowing out air directly cooled by the heat of vaporization of the sprayed water, and a heat exchanger 2. A second outlet 41 is provided, which is cooled by exchanging heat with the first air and blows out air for cooling the air-conditioned space into the air-conditioned space. The first air is synonymous with exhaust, and the second air is synonymous with supply air. The first outlet 31 corresponds to an exhaust outlet, and the second outlet 41 corresponds to an air supply / suction outlet.

The air conditioner 1 has a first flow path 3 through which first air that is directly cooled by the heat of vaporization of the sprayed water sprayed from the spraying portion 16 flows, and a first that is sucked from the suction port 51 and cooled. A suction flow path 5 through which air cooled by exchanging heat with air flows is provided. The air conditioner 1 includes a branching mechanism 6 that branches the suction flow path 5 into a first flow path 3 and a second flow path 4. The branch mechanism 6 includes a first fan 61 and a second fan 62 that function as a blower, and causes the suction air flowing through the suction flow path 5 to the first air flowing through the first flow path 3 and the second flow path 4. Divides into the flowing second air. Details of the branching mechanism 6 will be described later.

The suction flow path 5 is a flow path provided between the suction port 51 and the branch mechanism 6, and includes a suction path 22 of the sensible heat exchanger 2, which will be described later. A filter 52 formed of, for example, polyester or olefin fibers is provided in the suction flow path 5 in the vicinity of the suction port 51. The filter 52 collects dust in the air sucked from the suction port 51, and prevents the dust from entering the suction path 22 of the sensible heat exchanger 2.

The first flow path 3 is a flow path provided between the branch mechanism 6 and the first outlet 31, and includes the first path 21 of the sensible heat exchanger 2, which will be described later. The second flow path 4 is a flow path provided between the branch mechanism 6 and the second outlet 41.

The sensible heat exchanger 2 includes a suction path 22 that forms at least a part of the suction flow path 5, and a first path 21 that forms at least a part of the first flow path 3. The sensible heat exchanger 2 is provided with a box-shaped case made of metal or resin such as aluminum, and by providing a heat insulating member on the outer peripheral surface of the case, the first air flowing inside the sensible heat exchanger 2 is provided. Alternatively, the heat exchange between the suction air and the ambient air of the sensible heat exchanger 2 may be restricted.

The first path 21 and the suction flow path 5 formed in the sensible heat exchanger 2 are configured by, for example, providing a plurality of metal plates having a hollow structure through which the first air or the suction air flows in parallel. The metal plate having the hollow structure may be, for example, one composed of a plurality of fins or a flat tube. For example, the efficiency of sensible heat exchange can be improved by forming the plate with aluminum, copper, or the like, which are metals having good heat transfer properties, or an alloy containing these as main components. A plurality of the first path 21 and the suction path 22 are formed side by side by each of the plurality of metal plates having a hollow structure.

In the flow direction of the suction air, the inlet of the suction path 22 of the sensible heat exchanger 2 is provided on the left side surface below the sensible heat exchanger 2, and the outlet of the suction path 22 is above the sensible heat exchanger 2. It is provided on the right side of. Therefore, the suction path 22 of the sensible heat exchanger 2 is formed in a crank shape that communicates from the lower left inlet to the upper right outlet. In FIG. 2, the suction path 22 is formed in an inverted Z shape.

In the flow direction of the first air, the inlet of the first path 21 of the sensible heat exchanger 2 is provided above the sensible heat exchanger 2, and the outlet of the first path 21 of the sensible heat exchanger 2 is exposed. It is provided below the heat exchanger 2. Therefore, the first path 21 of the sensible heat exchanger 2 is formed in a straight line from the upper side to the lower side.

In the sensible heat exchanger 2, the first air flowing through the first path 21 flows from the upper side to the lower side, and the suction air flowing through the suction path 22 flows from the lower side to the upper side. The flows form countercurrents that are opposite to each other.

A spraying section 16 is provided above the inlet of the first path 21 of the heat exchanger 2, and the heat of vaporization of the mist-like water sprayed from the spraying section 16 causes the first path 21 to evaporate. The first air flowing through the air is cooled. The sensible heat exchanger 2 exchanges heat between the suction air flowing through the suction path 22 and the first air flowing through the first path 21, and the suction air is cooled by the first air. Since the flows of the first air and the suction air form a countercurrent, the heat exchange rate in the sensible heat exchanger 2 can be improved.

The suction air sucked from the air conditioning space through the suction port 51 passes through the filter 52 and then flows into the suction path 22 of the sensible heat exchanger 2. The suction air that has flowed into the suction path 22 of the sensible heat exchanger 2 is cooled by exchanging heat with the first air via the sensible heat exchanger 2. The sucked air that has been cooled and has passed through the suction path 22 of the sensible heat exchanger 2 flows into the branch chamber 63 of the branch mechanism 6 located on the downstream side of the suction path 22.

The sucked air that has flowed into the branching mechanism 6 is divided into a first air that flows through the first flow path 3 and a second air that flows through the second flow path 4. The second air flowing through the second flow path 4 is blown out from the second air outlet 41 (air supply air outlet) into the air-conditioned space to cool the air-conditioned space. The first air flowing through the first flow path 3 flows into the first path 21 of the sensible heat exchanger 2.

The first air flowing into the first path 21 is further cooled by the heat of vaporization of the sprayed water sprayed from the spraying portion 16 as described above. The first air flowing through the first path 21 exchanges heat with the suction air flowing through the suction path 22 via the sensible heat exchanger 2, so that the suction air is cooled. By dividing the suction air into the first air, the first air can be substantially cooled in two stages, and the temperature of the first air can be efficiently lowered. That is, by cooling the first air in two stages, the suction air can be cooled to a lower temperature than in the case where the suction air is only directly cooled by the heat of vaporization.

The second air blown out to the air-conditioned space is a divergence of the suction air, and the suction air is cooled by the first air via the sensible heat exchanger 2. As described above, since the first air is cooled in two stages and has a lower temperature, the suction air cooled by the first air is efficiently cooled, and the suction air cooled in this way is separated. 2 Air can be blown into the air-conditioned space to supply air.

The first air that has passed through the first path 21 of the sensible heat exchanger 2 is exhausted by being blown out to the air-conditioned space or the outdoor from the first air outlet 31 after passing through the drain pan 13 described later.

The air conditioner 1 includes a drain pan 13 provided below the heat exchanger 2, a tank 14 for storing the sprayed water sprayed from the spraying section 16, and a pump 11 for supplying the water in the tank 14 to the spraying section 16. ..

The drain pan 13 is, for example, a dish-shaped container having an opening on the upper surface. On the bottom surface of the drain pan 13, a communication passage for communicating with the tank 14 is provided. In the sprayed water sprayed from the spraying portion 16, the water that has not vaporized or the water that has condensed after vaporizing is dropped downward along the inner wall surface of the first path 21 of the sensible heat exchanger 2 and is dropped onto the drain pan 13. Is retained. The water in the drain pan 13 flows into the tank 14 through the continuous passage.

The tank 14 is provided with a water supply port (not shown), and tap water is replenished into the tank 14 through the water supply port. The tank 14 and the pump 11 communicate with each other by a pipe, and the water in the tank 14 is supplied to the spraying portion 16 by driving the pump 11.

The pump 11 is controlled to be driven or stopped by a control signal output from the controller 12. The controller 12 is composed of a microcomputer or the like including a control unit and a storage unit, and drives or stops the pump 11 and the first fan 61 and the second fan 62, which are blower units, based on the operation of the operator of the air conditioner 1. Take control.

The spraying unit 16 includes a spraying nozzle for spraying atomized water, and the spraying nozzle communicates with the tank 14 via a pipe and a pump 11. As described above, the water in the tank 14 is supplied to the spraying portion 16 by the pump 11, and is sprayed from the spraying nozzle toward the inlet of the first path 21 of the sensible heat exchanger 2.

The air conditioner 1 includes an electric device 17 including an electric component 171 and a storage battery 172. The electric device 17 is provided adjacent to the first path 21 of the sensible heat exchanger 2 and the first flow path 3 after passing through the drain pan 13. In other words, the electric device 17 is provided adjacent to the first flow path 3 between the downstream side of the drain pan 13 and the first outlet 31 in the flow direction of the first air.

The electric component 171 is, for example, a resistor, a coil, a capacitor, a semiconductor element, or the like, which generates heat when a voltage is applied and a current flows. Specifically, the electric component 171 includes a circuit board such as a control board or a power supply board on which these components are mounted. The electrical component 171 may be housed in a box such as an electrical component box. The electrical component 171 may include a controller 12. The storage battery 172 is, for example, a lithium ion battery, and when the air conditioner 1 is not connected to a commercial power source, it supplies electric power to an electric load such as a blower and a pump 11.

FIG. 3 is an explanatory diagram showing the branching mechanism 6. The branch mechanism 6 includes a blower unit, a first fan 61 that functions as the blower unit, and a branch chamber 63 that houses the second fan 62. In FIG. 3, the first fan 61 and the second fan 62 are described so as to be on the top and bottom, but they may be arranged back and forth in the depth direction of FIG.

The branching mechanism 6 branches the suction flow path 5 located on the downstream side of the suction path 22 into the first flow path 3 and the second flow path 4, thereby passing through the suction path 22 of the sensible heat exchanger 2. The air is divided into the first air flowing through the first flow path 3 and the second air flowing through the second flow path 4. Therefore, the suction flow path 5 communicates with the first flow path 3 and the second flow path 4 via the branch chamber 63.

The first fan 61 and the second fan 62 are centrifugal fans such as a turbo fan, and have a suction portion 611 and 621 located at the center and a blowout portion 612 and 622 extending in one direction. The suction portion 611, 621 and the blowout portion 612, 622 are provided on the shell member forming the outer shell of the turbofan. The first fan 61 and the second fan 62 are provided in the branch chamber 63 so that a part thereof overlaps with each other.

The first fan 61 is provided with the blowout portion 612 facing the first flow path 3. A spraying portion 16 is provided in the first flow path 3, and the blowing portion 612 of the first fan 61 is directed to the spraying portion 16. The first fan 61 blows out a part of the suction air that has flowed into the branching mechanism 6 into the first flow path 3 as the first air. The first air blown out from the first fan 61 is guided to the spraying portion 16 by the guide wall 32 provided in the first flow path 3.

The second fan 62 is provided with the blowout portion 622 facing the second flow path 4. The second flow path 4 communicates with the second outlet 41, and the outlet portion 622 of the second fan 62 faces the second outlet 41. The second fan 62 blows out a part of the suction air that has flowed into the branching mechanism 6 into the second flow path 4 as the second air. The second air blown out from the second fan 62 is supplied to the air-conditioned space from the second air outlet 41.

The blowout portions 612 and 622 of the turbofan have a shape extending in one direction, and the air blown from the blowout portions 612 and 622 of the turbofan has directivity toward the extension direction of the blowout portions 612 and 622. Therefore, the first fan 61 can efficiently blow out the suction air sucked from the suction section 611 from the blowout section 612 toward the spray section 16. In addition, the second fan 62 can efficiently blow out the suction air sucked from the suction section 621 from the blowout section 622 toward the second outlet 41.

The first path 21 branched by the branching mechanism 6 and the second path are extended in different directions so as to be opposite to each other. Similarly, the blowout portion 612 of the first fan 61 and the blowout portion 622 of the second fan 62 are oriented in different directions so as to be opposite to each other.
Therefore, when the first air and the second air separated by the first fan 61 and the second fan 62 are blown out from the first path 21 and the second path, interference by the first air and the second air is suppressed and ventilation is performed. It is possible to reduce the generation of resistance.

The first fan 61 and the second fan 62 are communicably connected to the controller 12, and drive or stop rotation or the like based on the control signal output from the controller 12. The controller 12 rotates the first fan 61 and the second fan 62 based on the operation content input from the operator of the air conditioner 1 or by executing a program stored in the storage unit of the controller 12. May be different to control the volumetric flow rates of the first air and the second air. By controlling the volumetric flow rates of the first air and the second air, the types of operation modes of the air conditioner 1 can be increased.

As shown in FIG. 1, the branching mechanism 6 is provided above the sensible heat exchanger 2. The suction path 22 is provided from below to above in the flow direction of the suction air. Since the suction path 22 forms a part of the suction flow path 5, the suction flow path 5 is provided from the lower side to the upper side in the flow direction of the suction air. The first path 21 is provided from the upper side to the lower side in the flow direction of the first air. Since the first path 21 forms a part of the first flow path 3, the first flow path 3 is provided from the upper side to the lower side in the flow direction of the first air.

The branching mechanism 6 is provided at a turning point by a suction flow path 5 provided from the lower side to the upper side and a first flow path 3 provided from the upper side to the lower side. In FIG. 1, a portion where the flow path is folded back by about 270 degrees in the vicinity of the branching mechanism 6 is a turning point. Where a U-shaped flow path is formed by the suction flow path 5 provided from the lower side to the upper side and the first flow path 3 provided from the upper side to the lower side, the U-shaped flow path is formed. By providing a branching mechanism 6 provided with a blower portion at a turning point in the flow path of the above, the influence of pressure loss in the U-shaped flow path can be mitigated. Although the case where the branching mechanism 6 is provided at the turning point above the sensible heat exchanger 2 has been described, if it is provided within the range of the turning point, it can contribute to the alleviation of pressure loss. As an example, the suction portion 611 and the suction portion 621 may be adjacent to the outlet of the suction path 22 in FIG. In that case, it can be easily deformed by providing a wall surface or the like that defines the directions and flow paths of the blowout portions 612 and 622 of each fan in the direction of the first path 21 or the direction of the second outlet 41.
