Thus, the inside of the pipes 72 and 73 communicates with the ventilation space SC, and heat can be discharged from the inside of the pipes 72 and 73 to the outside of the unit body 36 through the ventilation space SC. Since no wiring is stored in the pipe 73 and the pipe 73 and the ventilation space SC communicate with each other, the pipe 73 also serves as the ventilation space SC while being the wiring space SA. . That is, the wiring space SA and the ventilation space SC are combined. In the unit body 36, a ventilation space SC is provided between the heat insulation space SB and the wiring space SA.

The power storage system 40 is configured to include a solar cell module 22, a power conditioner 24, and a storage battery 26. For the power storage system 40, a vehicle mounted on an electric device 27 or a vehicle in the building 10. A storage battery 29 is connected to be supplied with power. Here, the control apparatus 43 is comprised including the power conditioner 24 and the storage battery 26, The charge from the solar cell module 22 to the storage battery 26 or the discharge of the storage battery 26 is controlled by this control apparatus 43. It is like that.

  As the storage battery 26, for example, a storage battery such as a lithium ion storage battery, a lead storage battery, or a nickel hydride storage battery is applicable, but other storage batteries such as a nickel cadmium storage battery may be used. A battery (solid polymer fuel cell) may be used. Incidentally, lead storage batteries and nickel metal hydride storage batteries are controlled with heat generated up to about 40 ° C., and lithium ion storage batteries are controlled with heat generated up to about 60 ° C. And the fuel cell is controlled by the generated heat to about 60-70 degreeC.

  The storage capacity of the storage battery 26 is set differently depending on the size of the load at each location where the storage battery 26 is installed. That is, some storage batteries 26 have a large storage capacity, some storage batteries 26 have a medium storage capacity, and some storage batteries 26 have a small storage capacity. There are two ways to change the storage capacity of the storage battery 26, one is a method of connecting the required number of storage batteries 26 of the same capacity to increase the storage capacity by an integral multiple, and the other is required. This is a method of preparing and installing in advance a storage battery 26 that can cover the storage capacity alone.

  In the former case, it is not necessary to prepare a plurality of types of storage batteries 26 having different storage capacities in advance, so that the connection work can be abolished, and the cost can be reduced accordingly. On the other hand, in the latter case, since the necessary storage capacity is covered by the single storage battery 26, the installation space can be reduced as compared with the case where the storage battery 26 is connected to increase the capacity. Which one to select is determined in consideration of the size and cost of the storage battery 26 that can be secured.

Can do. Further, since the electric power stored in the storage battery 26 can be used via the external outlet 48 outside the building 10, it is not necessary to supply power from the outlet in the building 10 using an extension cord, and the device operates with electric power. Etc. (for example, the vehicle storage battery 29) can be easily used. Furthermore, as shown in FIG. 2, since the operation state of the solar cell module 22 can be confirmed through the window portion 44 without removing the outer wall panel 38, or the power conditioner 24 can be directly operated, the maintenance is simplified. It can be carried out.

  Further, as shown in FIGS. 4A and 4B, in the lower equipment unit 32 and the upper equipment unit 34, even if the temperature of the wiring space SA changes due to a change in the external temperature, the wiring space SA changes to the building 10. The heat conducted to (see FIG. 1) is insulated in the heat insulation space SB. Furthermore, when the insides of the unit bodies 36 and 54 are in a high temperature state, the high temperature air is prevented from flowing out from the ventilation space SC and the insides of the unit bodies 36 and 54 are continuously in a high temperature state. The Thereby, the heat transfer from the lower equipment unit 32 and the upper equipment unit 34 to the building 10 is suppressed, and it is possible to suppress the temperature inside the building 10 from being affected by the outside air temperature.

  Furthermore, in the lower equipment unit 32 and the upper equipment unit 34, the heat insulating materials 82, 84, and 85 are provided in the heat insulating space SB, so that heat insulation inside the building 10 is achieved as compared with the case where heat insulation is performed using an air layer. The effect can be improved. In the lower equipment unit 32 and the upper equipment unit 34, even if the temperature of the air in the wiring space SA rises, the air is exhausted to the outside through the ventilation space SC and is insulated by the heat insulation space SB. Therefore, the heat insulation effect inside the building 10 can be increased.

  Further, as shown in FIG. 4A, in the lower equipment unit 32, when a part of the wiring is unnecessary, the wiring space SA becomes the ventilation space SC by removing the wiring as in the piping 73, and is heated. Air is discharged from the upper end of the lower equipment unit 32 through the pipe 73. Further, in the pipe 73, the warmed air inside (wiring space SA) flows out to the outside of the lower equipment unit 32 through the plurality of holes 73A, so that the temperature rise inside the pipe 73 can be suppressed. Thereby, the heat transfer to the building 10 is suppressed and the heat insulation effect inside the building 10 can be improved. In addition, when it becomes necessary to provide a new wiring, it is only necessary to pass the wiring through the pipe 73 that is also used as the ventilation space SC, so that it is not necessary to separately secure a space for the wiring.

  Further, as shown in FIGS. 4A and 4B, in the lower equipment unit 32 and the upper equipment unit 34, the louvers 42 and 58 are not provided on the heat insulation space SB side, so that the installation area of the heat insulation space SB is reduced. It is restrained and it can prevent that the heat insulation effect inside the building 10 falls. As shown in FIG. 1, in the equipment unit 30, the lower equipment unit 32 and the upper equipment unit 34 (unit main bodies 36 and 54) are respectively provided on the first floor portion 14 and the second floor portion 16 of the building 10. Heat transfer to the building 10 can be suppressed according to the wiring state of each floor. Further, since the inside of the unit main bodies 36 and 54 is continuous, a large space is formed, so that the warmed air does not stay in the narrow space, and the heat insulating effect of the building 10 can be enhanced.

  In addition, as shown in FIG. 7, as a modification of the building 10 and the equipment unit 30 of the first embodiment, in addition to the solar cell module 22 (see FIG. 1), the outer wall panels 38 and 56 are also subjected to solar power generation. A solar cell module 92 may be provided. According to this configuration, the amount of power stored by the storage battery 26 can be increased.
