Is a fan guard composed of a net.

The operation of the air conditioner of this embodiment as described above will now be described.

During the cooling operation of the air conditioner, the four-way valve 4
0 is controlled to the state shown by the solid line in FIG. When the compressor 7 is driven by the engine 6 in this state,
The high-pressure gaseous refrigerant discharged from the compressor 7 is sent to the refrigerant outdoor heat exchanger 11 through the discharge side pipe 41, the four-way valve 40, and the pipe 43, and the refrigerant outdoor heat exchanger 11 The refrigerant functions as a condenser, in which the refrigerant is cooled by the outside air and liquefied, and the refrigerant liquid passes through the heat exchanger 71, the pipes 44 and 48, and is expanded and decompressed by the throttle 4, and then the refrigerant indoor heat exchanger. Sent to 3. Then, the refrigerant indoor heat exchanger 3 functions as an evaporator, where the refrigerant takes heat from the room and evaporates, thereby performing cooling. The evaporated refrigerant passes through the pipe 49, the pipe 45, the four-way valve 40, and the suction-side refrigerant pipe 42, and is returned to the compressor 7 through the accumulators 8 and 9.

On the other hand, during heating, the four-way valve 40 is controlled to the state shown by the broken line in FIG. In this state, when the compressor 7 is driven by the engine 6, the refrigerant discharged from the compressor 7 passes through the discharge-side refrigerant pipe 41, the four-way valve 40, the pipe 45, and the pipe 49, and heats the refrigerant indoor heat. The refrigerant is sent to the exchanger 3, and the refrigerant indoor heat exchanger 3 functions as a condenser, where the refrigerant releases heat into the room and liquefies, thereby performing heating. The liquefied refrigerant is expanded and decompressed by the throttle 4, and then sent to the refrigerant outdoor heat exchanger 11 through the pipe 48, the pipe 44, and the heat exchanger 71, and the refrigerant indoor heat exchanger 3 evaporates. Where the refrigerant takes away the heat of the outside air and evaporates, and the evaporated refrigerant passes through the pipe 43, the four-way valve 40,
The refrigerant passes through the suction-side refrigerant pipe 42 and returns to the compressor 7 via the accumulators 8 and 9.

By the way, when the fan 90 is driven during the cooling or heating operation as described above, air is forcibly sent out from the outdoor heat exchange chamber 10 to the outside.
Accompanying this, outside air flows into the outdoor heat exchange chamber 10 from the front and rear wire meshes 108, and the flow of air promotes heat exchange in the refrigerant outdoor heat exchanger 11 and the radiator 12.

Further, air flows from the engine room 5 to the outdoor heat exchange room 10 by driving the fan 90, and accordingly, outside air flows into the engine room 5 from the floor 101, and the engine room 5
Ventilation is provided. That is, the outside air is supplied to the floor frame 110.
The air flows into the floor frame 110 from an air inlet 113 provided in the floor panel 110, and further blows out into the engine room 5 from an air circulation hole 119 provided in the floor panel 118. After the air has been ventilated and cooled in the engine room 5, the air flows from the air circulation holes 123 formed in the plate 122 of the partitioning section 103 through the air circulation path inside the lid member 125, and passes through the air outflow holes 12.
6 to the outdoor heat exchange chamber 10, and the refrigerant outdoor heat exchanger 1
1 and the radiator 12 flow out inside the portion where the radiator 12 is disposed, and flow out above the outdoor heat exchange chamber 10.

As described above, the partitioning section 103 allows the air after ventilation of the engine room to flow into the outdoor heat exchange chamber 10 while separating the engine room 5 from the outdoor heat exchange chamber 10. In addition to such functions, the partitioning section 103 is configured to enhance functions such as improvement of maintainability and reduction of vibration noise.

That is, the frame 121 of the partition 103
The plate 122 is detachable from the
By removing 22, the space on both sides of the center section 121b inside the edge frame 121a is opened, which is convenient for maintenance of the engine 6 and the like in the engine room 5.

Further, the frame 121 of the partitioning section 103 is reinforced by a center section bar 121b.
The plate 122 supported on the upper side is divided into left and right parts, each of which is reinforced by a peripheral edge frame 122a, and the rigidity of the central part is increased by fixing and integrating the lid member 125. The rigidity of the frame 121 and the plate 122 is increased, and the film vibration of the plate 122 is suppressed, as compared with a case where a plate having a large size is supported by a frame including only the edge frame. Moreover,
Since the plate 122 is floatingly supported via the rubber mount material 124, transmission of engine vibrations and the like to the plate 122 via the frame 121 is suppressed. By these actions, resonance of the plate 122 during operation is sufficiently suppressed, and noise is reduced.

Further, a lid member 125 is provided on the plate 122 at a position where the air circulation hole is formed.
Is formed in a meandering shape, so that a noise reduction effect is obtained and the engine room 5 to the outdoor heat exchange chamber 1
The emission of sound through 0 is suppressed. This lid member 125
Indicates that water droplets dropped on the partition 103 are
It also has the function of preventing the vehicle from entering the engine room 5 through 3. Further, the rubber mount member 124 has an opening 121.
Since it is formed in an annular shape along the periphery of d, the engine room and the outdoor heat exchange chamber communicate with each other only through the air circulation hole 123, and the lid member 125 more reliably performs a silencing operation.
