The heating element 3 has a warm air discharge port 3a for discharging generated heat at the upper portion, and an intake port 3b for sucking in air for cooling itself.

  As shown in FIG. 2, the cooling device 4 integrally includes a circulation unit 11, a heat exchanger 12, and a cooling unit 13. The cooling device 4 has a cubic shape whose outer shape is long in the vertical direction, and a heat exchanger 12 is arranged in the upper part and a cooling means 13 is arranged in the lower part. The cooling device 4 has a suction port 14 for sucking air at the upper part of one side surface, and has a blower outlet 15 for blowing air on the bottom surface. The cooling device 4 has a ventilation path extending from the suction port 14 to the blowout port 15 via the heat exchanger 12 and the cooling means 13.

  As shown in FIG. 1, the cooling device 4 is attached along the outer surface of the building 2. The cooling device 4 is attached by aligning the suction port 14 with the exhaust port 2 b of the building 2 and connecting the air outlet 15 and the supply port 2 c of the building 2 with a duct 16.

  As shown in FIG. 2, the circulation means 11 includes a fan and is provided on the downstream side of the suction port 14. The circulation means 11 is configured to blow out the air sucked from the suction port 14 from the blowout port 15 through the ventilation path. That is, the circulation means 11 sucks the air in the storage chamber 2a from the exhaust port 2b of the building 2 through the intake port 3b, passes through the heat exchanger 12 and the cooling unit 13, and passes through the duct 16 from the blowout port 15 through the duct 16. It is configured to return to the storage chamber 2a from the supply port 2c.

  The heat exchanger 12 is a commercially available boiling-cooling type, and is configured to cool the air in the storage chamber 2 a sucked by the circulation means 11 by heat exchange with the air outside the building 2. The cooling means 13 is made of a commercially available air conditioner, and can further cool the air cooled by the heat exchanger 12. The cooling means 13 has a control board 13a, and when the air cooled by the heat exchanger 12 is higher than a preset temperature, the air is cooled to the preset temperature, and the air cooled by the heat exchanger 12 When is below the set temperature, the operation is stopped and the air is allowed to pass through without cooling. The set temperature is 30 ° C., for example. In the specific example shown in FIG. 1, the heat exchanger 12 has a cooling capacity of 3.6 kW and a rated power consumption of 0.15 kW. The cooling means 13 has a cooling capacity of 7 kW and a rated power consumption of 2.4 kW.

Next, the operation will be described.
The cooling system 1 can cool the air in the storage room 2 a of the building 2 by the heat exchanger 12 and the cooling means 13 of the cooling device 4. At this time, since the cooling burden can be distributed to the heat exchanger 12 and the cooling means 13, even when the storage chamber 2 a for storing the heating element 3 that generates a large amount of heat is cooled, it is large and high. It is not necessary to use the heat exchanger 12 with high performance, and the equipment cost can be reduced. Moreover, after cooling with the heat exchanger 12 with low power consumption, it is sufficient to cool with the cooling means 13 as necessary. Therefore, the power consumption of the cooling means 13 can be suppressed, and the operating cost can be reduced. As described above, the cooling system 1 can efficiently cool the air in the storage room 2a with low power consumption and low cost even in the building 2 that stores the heating element 3 that generates a large amount of heat. In the specific example shown in FIG. 1, the cooling device 4 can cool the storage room 2 a of the building 2 with 1/5 power consumption as compared with the case of cooling only with an air conditioner.

  The cooling system 1 sucks high-temperature air in the storage room 2a from the exhaust port 2b in the upper part of the building 2 by the circulation means 11, cools it, and returns it from the supply port 2c in the lower part of the building 2. Air can be cooled efficiently. Further, since the circulation means 11, the heat exchanger 12, and the cooling means 13 are attached to the outside of the building 2 without using the space of the storage room 2a, it is an obstacle when the heating element 3 is installed in the storage room 2a.

In particular, when the air sucked from the storage chamber 2a becomes equal to or lower than the set temperature only by cooling the heat exchanger 12, the cooling means 13 can be stopped and the power consumption can be further reduced. For example, since the temperature of the air sucked from the storage room 2a becomes high in the hot summer season, it is necessary to operate the cooling means 13. However, in the cool autumn season, spring, and cold winter season, the cooling means 13 is hardly operated. The storage chamber 2a can be cooled, and the power consumption can be reduced.

  The cooling system 1 can transport and attach the cooling device 4 by integrating the circulation means 11, the heat exchanger 12, and the cooling means 13, and can efficiently install the cooling device 4. In addition, pipes and wirings between the circulation means 11, the heat exchanger 12, and the cooling means 13 can be integrally incorporated in the cooling device 4, and it is not necessary to route them outside, so that it is difficult to break down. . Moreover, since the cooling device 4 can be attached along the outer surface of the building 2, piping and wiring between the building 2 can be reduced as much as possible, and the cooling device 4 can be easily attached to the building 2. .

  The cooling system 1 may be configured to blow air toward the intake port 3b of the heating element 3 when returning air from the supply port 2c to the storage chamber 2a by the circulation means 11. In this case, the heating element 3 can be efficiently cooled by the air cooled by the cooling device 4 and directly blown to the air inlet 3b of the heating element 3. Thereby, the temperature rise of the air of the storage chamber 2a can be suppressed, and the power consumption of the cooling device 4 can be suppressed.

  Further, as shown in FIG. 3, the cooling system 1 may have a warm air guiding means 21 provided in the storage chamber 2a so as to collect the air heated by the heating element 3 and guide it to the exhaust port 2b.

The ceiling board 22 has an opening 23 above the warm air outlet 3a of the heating element 3 so that air heated by the heating element 3 can be collected. In the example shown in FIG. 3B, the warm air guiding means 21 includes an exhaust duct 24 connected from the warm air discharge port 3 a to the exhaust port 2 b of the heating element 3.

  When the warm air guiding means 21 is provided, the air warmed by the heating element 3 can be guided to the exhaust port 2b by the warm air guiding means 21 without being mixed with most of the other air in the storage chamber 2a. . For this reason, while preventing most other air from being warmed by the heat generating body 3, only the warmed air can be cooled, and the cooling efficiency is high.

  In addition, as shown in FIG. 4, the cooling system 1 includes a cool air induction means 31 provided in the storage chamber 2a so as to guide the air returned from the supply port 2c to the storage chamber 2a to the intake port 3b of the heating element 3.

In the example shown in FIG. 4 (a), the cold air guiding means 31 is composed of a double-floor underfloor space in which the lower portion of the storage chamber 2a is provided by a partition floor plate 32 so as to include the supply port 2c. . In the underfloor space of the double floor, the cooled air returned from the supply port 2c can be stored. The floor plate 32 has an opening 33 at a position corresponding to the air inlet 3b so that the cooled air can be supplied to the air inlet 3b of the heating element 3. In the example shown in FIG. 4B, the cool air guiding means 31 includes a supply duct 34 connected from the supply port 2 c to the intake port 3 b of the heating element 3, and the cooled air is used as the intake port of the heating element 3. It is comprised so that it may spray toward 3b.

  When the cold air guiding means 31 is provided, the air cooled by the cooling device 4 can be directly guided to the air inlet 3b of the heating element 3 without being mixed with the air in the storage chamber 2a. . For this reason, the heat generating body 3 can be cooled only by the cooled air, and the cooling efficiency of the heat generating body 3 is high. Thereby, the temperature rise of the air of the storage chamber 2a can be suppressed, and the power consumption of the cooling device 4 can be suppressed.
