  On the other hand, an underfloor air supply port 50 as a first air supply port is formed on the floor of the storage battery storage chamber 16, and the storage battery storage chamber 16 and the underfloor space 52 communicate with each other through the underfloor air supply port 50. Has been. The underfloor air supply port 50 uses an opening originally formed when the building unit 22 is disposed adjacent to the floor unit.

  The underfloor air supply port 50 is provided with an underfloor air supply fan 54 as an air supply side fan. The underfloor air supply fan 54 rotates when the underfloor air supply fan motor 56 (see FIG. 5) is driven to suck and supply the air in the underfloor space 52 to the storage battery storage chamber 16.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.

  In the present embodiment, the storage battery storage chambers 16, 18, and 20 are provided using a dead space formed in the indoor space 14 of the unit building 10, and the storage battery 42 is provided in the storage battery storage chambers 16, 18, and 20. Stored. By the way, generally, a narrow space along the height direction of the building is not easy to use, so it is often not used effectively and becomes a dead space. However, even in such a narrow and unusable space, the space in the unit building 10 can be effectively used by using the storage battery storage chambers 16, 18, and 20 for storing the storage battery 42. .

  Here, based on the following Table 1, the temperature control in the said storage battery storage chamber 16,18,20 is demonstrated.

In the present embodiment, the storage room temperature detection sensor 78, the underfloor temperature detection sensor 82, and the indoor temperature detection sensor 80 use the storage battery storage room temperature t <b> 1 that is the air temperature in the storage battery storage room 16, and the underfloor temperature that is the air temperature in the underfloor space 52. The indoor temperature t3, which is the temperature of the room 70, is detected at t2, and is output to the controller 58. In the controller 58, the switching control of the underfloor switching damper 62 and the indoor switching damper 72 and the operation control of the underfloor air supply fan 54 are performed based on these detection results t1, t2, and t3.

≪When t1 ≧ 30 ℃ ≫
If the storage battery storage room temperature t1 in the storage battery storage room 16 is 30 ° C. or higher (in the high temperature range), the summer mode shown in FIG. The control is performed by dividing into five.

  Specifically, when the storage battery storage room temperature t1 is 30 ° C. or higher and the underfloor temperature t2 is higher than the storage battery storage room temperature t1, the temperature in the storage battery storage room 16 is too high and the temperature in the underfloor space 52 is It will be even higher than that. In such a case, even if air is supplied from the underfloor space 52, the temperature in the storage battery storage chamber 16 cannot be lowered, so the underfloor switching damper 62 is closed by the controller 58.

  Then, the above case is further classified into patterns 1 to 3, and if the indoor temperature t3 is equal to or higher than the underfloor temperature t2 at that time, the temperature of the room 70 is higher than the temperature in the underfloor space 52. Therefore, the indoor switching damper 72 is closed by the controller 58 (pattern 1).

  If the room temperature t3 is lower than the underfloor temperature t2 but still higher than the temperature t1 in the storage battery storage chamber 16, the temperature of the storage battery storage chamber 16 cannot be lowered even if air is supplied from the room 70. Both the underfloor switching damper 62 and the indoor switching damper 72 are closed (pattern 2).

  However, when the room temperature t3 is equal to or lower than the temperature t1 in the storage battery storage chamber 16, the underfloor switching damper 62 is closed and the indoor switching damper 72 is opened (pattern 3) by the controller 58. As a result, the air in the room 70 flows into the storage battery storage chamber 16 from the indoor air supply port 68, and the storage battery storage room temperature t1 in the storage battery storage room 16 is lowered. As a result, the inflowing air in the room 70 and the storage battery 42 exchange heat, the temperature of the storage battery 42 is lowered, and the air that has been deprived of heat and exhausted is exhausted from the exhaust port 44 to the ceiling space 46.

  In the pattern 3, when the ceiling exhaust fan 60 is installed in the exhaust port 44, the controller 58 operates the ceiling exhaust fan 60 to forcibly flow the air in the room 70 into the storage battery storage chamber 16. You may make it make it.

  On the other hand, when the underfloor temperature t2 is lower than the storage battery storage room temperature t1, the underfloor switching damper 62 is opened by the controller 58, and the indoor switching damper 72 is closed (patterns 4 and 5). As a result, the underfloor air supply port 50 is opened, and the underfloor air supply fan motor 56 is driven and rotated by the controller 58 to rotate the underfloor air supply fan 54. When the underfloor air supply fan 54 is operated, the air in the underfloor space 52 is forcibly taken into the storage battery storage chamber 16 to lower the temperature of the storage battery 42. Air deprived of heat from the storage battery 42 is exhausted from the exhaust port 44 into the ceiling space 46. In addition, you may perform this control including the case where the underfloor temperature t2 is the same as the storage battery storage room temperature t1.

  Further, when the underfloor temperature t2 is lower than the storage battery storage chamber temperature t1 in the storage battery storage chamber 16, the magnitude relationship between the indoor temperature t3 and the underfloor temperature t2 does not matter. That is, even if the temperature t3 in the room 70 is higher or lower than the underfloor temperature t2, control is performed to supply the air in the underfloor space 52 and cool the storage battery 42. However, the control may be further refined, and in the case of pattern 5, the underfloor switching damper 62 may be closed and the indoor switching damper 72 may be opened, or both may be opened.

≪When 10 ℃ <t1 <30 ℃ ≫
The storage battery storage room temperature t1 in the storage battery storage room 16 is basically shown in FIG. 1 even when it is higher than 10 ° C. and lower than 30 ° C. (in the middle temperature range), which is appropriate for storage of the storage battery 42. The summer mode.

  In this case, when the underfloor temperature t2 is equal to or higher than the storage battery storage room temperature t1, the underfloor switching damper 62 is opened by the controller 58 and the indoor switching damper 72 is closed regardless of the indoor temperature t3. (Patterns 6 and 7). However, in the sense of finer control, in the case of pattern 7, the storage battery 42 is not directly cooled even if the air in the underfloor space 52 is taken into the storage battery storage chamber 16. The underfloor switching damper 62 may be closed and the indoor switching damper 72 may be open. Then, the air in the room 70 having a temperature lower than that of the air in the underfloor space 52 is supplied from the indoor air supply port 68 into the storage battery storage chamber 16, so that the storage battery 42 is cooled.

  Even when the underfloor temperature t2 is lower than the storage battery storage room temperature t1, the underfloor switching damper 62 is opened by the controller 58 and the indoor switching damper 72 is closed regardless of the indoor temperature t3. (Patterns 8 and 9). Thereby, the air in the underfloor space 52 flows into the storage battery storage chamber 16 from the underfloor air supply port 50, and cools the storage battery 42. In this case, it is more effective if the underfloor air supply fan 54 is operated by driving and rotating the underfloor air supply fan motor 56.

  Supplementally, in general, the underfloor temperature t2 in the underfloor space 52 is lower than the storage battery storage room temperature t1 in the storage battery storage room 16 in both summer and winter. For this reason, even if there is a situation in which the underfloor temperature t2 becomes equal to or higher than the storage battery storage room temperature t1 as in the patterns 6 and 7 in summer, the pattern moves to the patterns 8 and 9 in a short time, and the underfloor temperature t2 is The situation lower than the storage room temperature t1 becomes dominant. In that sense, the underfloor temperature detection sensor 82 is not necessarily essential, and it is possible to omit the underfloor temperature detection sensor 82 on the assumption that the underfloor temperature t2 is always equal to or lower than the storage battery storage room temperature t1.

≪When t1 ≦ 30 ℃ ≫
When the storage battery storage room temperature t1 in the storage battery storage room 16 is 10 ° C. or lower, the winter mode shown in FIG. 2 is basically set, and control is performed by dividing the pattern 10 to the pattern 13. The

  Specifically, when the storage battery storage room temperature t1 is 10 ° C. or lower and the underfloor temperature t2 is higher than the storage battery storage room temperature t1, the temperature in the storage battery storage room 16 is too low and the temperature in the underfloor space 52 is It will be higher than. In such a case, the controller 58 opens the underfloor switching damper 62 and closes the indoor switching damper 72 to increase the temperature in the storage battery storage chamber 16 by supplying air in the underfloor space 52. (Patterns 10 and 11). Thereby, the air in the underfloor space 52 flows into the storage battery storage chamber 16 from the underfloor air supply port 50 and warms the storage battery 42. In this case, it is more effective if the underfloor air supply fan 54 is operated by driving and rotating the underfloor air supply fan motor 56. Moreover, when this underfloor temperature t2 is higher than the temperature t1 in the storage battery storage chamber 16, the magnitude relationship between the indoor temperature t3 and the underfloor temperature t2 is not ask | required.

  On the other hand, when the underfloor temperature t2 is lower than the storage battery storage room temperature t1, the air in the storage battery storage room 16 is too cold and the temperature in the underfloor space 52 is lower than this. The underfloor switching damper 62 is closed by the controller 58. When the indoor temperature t3 of the room 70 is equal to or higher than the underfloor temperature t2, the air in the room 70 is warmer (by indoor heating or the like) than the air in the underfloor space 52. Therefore, the indoor switching damper 72 is opened by the controller 58 (pattern 12).

  On the other hand, when the room temperature t3 in the room 70 is lower than the underfloor temperature t2, the room switching damper 72 is closed by the controller 58 because the room 70 is cooled because it is not heated (pattern). 13).

  Note that 10 ° C. in the above control corresponds to the “first predetermined temperature” in the present invention, and 30 ° C. corresponds to the “second predetermined temperature” in the present invention. However, these 10 degreeC and 30 degreeC are examples, and are adjusted by the area, the structure of a building, the specification of a storage battery, etc. The case where the storage battery storage room temperature t1 is 10 ° C. <t1 <30 ° C. corresponds to the “medium temperature range” in the present invention, and the case where the storage battery storage room temperature t1 is t1 ≧ 30 ° C. is the “high temperature range” in the present invention. The case where the storage battery storage room temperature t1 is t1 ≦ 10 ° C. corresponds to the “case of the low temperature range” in the present invention.

  Moreover, although mentioned suitably in description of the said control, since the control pattern shown in Table 1 is an example to the last, it changes suitably according to a need. However, temperature control is performed based on the storage battery storage room temperature t1 in the storage battery storage room 16. Furthermore, when there are a plurality of detected temperatures, the storage battery storage room temperature t1 has the highest priority.

  Thus, in the present embodiment, the air supply flow path is switched depending on whether the storage battery storage room temperature t1 of the storage battery storage room 16 is in the intermediate temperature range or the low temperature range, so that the performance of the storage battery 42 can be improved even in summer and winter. Can keep good. In other words, the opening / closing control of the underfloor switching damper 62 and the indoor switching damper 72 and the operation control of the underfloor air supply fan 54 (and the ceiling exhaust fan 60) are performed so that the temperature in the storage battery storage chamber 16 is approximately in the middle temperature range throughout the year. Since it performed, the performance of the storage battery 42 can be maintained favorable throughout the year.

  In the present embodiment, the underfloor air supply fan 54 is installed in the underfloor air supply port 50, or the ceiling exhaust fan 60 is installed in the exhaust port 44, and the storage battery storage room temperature t1 is a second predetermined temperature of 30 ° C. In the case described above (patterns 4 and 5), the controller 58 forcibly operates the underfloor air supply fan 54 or the ceiling exhaust fan 60. For this reason, it is possible to respond more rapidly to a rapid temperature change in the storage battery storage chamber 16 than in the case of natural ventilation.

  Furthermore, in this embodiment, the indoor temperature detection sensor 80 is installed in the room 70, the storage battery storage room temperature t1 is 10 ° C. or less which is the first predetermined temperature, and the room temperature detected by the room temperature detection sensor 80. When t3 is equal to or higher than the underfloor temperature t2 (in the case of pattern 12), the underfloor switching damper 62 is closed and the indoor switching damper 72 is opened by the controller 58. For this reason, when the room 70 is sufficiently warmed by heating or the like in winter or the like, the air in the room 70 having a temperature relatively higher than the storage battery storage room temperature t1 is taken into the storage battery storage room 16. Thereby, the air in the storage battery storage chamber 16 can be warmed and the performance of the storage battery 42 can be maintained. That is, the opening / closing control of the indoor switching damper 72 is performed in consideration of the temperature of the room 70. As a result, it is possible to prevent the storage battery 42 stored in the storage battery storage chamber 16 from being excessively cooled.
