It may be in a form of communicating with the exhaust port of the resistance portion 73.

(About air flow)
Next, the flow of air via the air guiding unit 91 and the air discharging unit 92 will be described.
As an initial state, the generator 50 and the load test device 70 are installed in the generator storage rack 60.
The generator 50 is electrically connected to the cooling fan 71a of the load test device 70 and the vending machine 10, and when the generator 50 is turned on, power is supplied to the cooling fan 71a and the vending machine 10. It is in a possible state.
Air so that the side of the first induction pipe 91a where the check valve 91c is located communicates with the rear opening 19a on the side of the first vending machine, and the first collecting unit 91b communicates with the intake port of the cooling unit 71 of the load test device 70. The guide portion 91 is attached to the back surface 10b of the vending machine 10 or the back wall 62 of the generator storage rack 60.
The air discharge section 92 communicates with the exhaust port of the resistance section 73 of the load test device 70, and the other end of the second guide tube 92a opens outside the generator storage rack 60. , Attached to the load test device 70.
When the power is supplied from the commercial power source, the generator 50 is turned off in the normal use mode.

When performing a load test of the generator 50 or a load test of another power source to be tested, the load test device 70 releases the state in which the air guide unit 91 and the air discharge unit 92 are attached, and the generator is used. It is taken out from the storage rack 60.
After the load test is completed, the load test device 70 is installed in the generator storage rack 60 and is connected to the air guiding unit 91 and the air discharging unit 92.

When the power supply from the commercial power source is not performed, the generator 50 is turned on in the first emergency mode or the second emergency mode to supply power to the vending machine 10.
If the temperature T outside the vending machine 10 is not higher than the first temperature threshold T1 while the vending machine 10 is receiving power from the generator 50, the generator is in the second emergency mode. 50 does not supply power to the cooling fan 71a of the load test device 70.
In the normal use mode and the second emergency mode, the cold air of the vending machine 10 is not sucked from the cooling fan 71a of the load test device 70 through the air induction unit 91.

If the temperature T outside the vending machine 10 is higher than the first temperature threshold T1 while the vending machine 10 is receiving power from the generator 50, the generator 50 is in the first emergency mode. Supplys power to the cooling fan 71a of the load test apparatus 70.
In the first emergency mode, the cold air of the vending machine 10 is sucked from the cooling fan 71a of the load test device 70 through the air guiding unit 91.

When the cooling fan 71a rotates so as to send air to the resistance portion 73, the air guide portion 91 attached to the intake port of the cooling portion 71 becomes a negative pressure, and the check valve 91c opens.
As a result, a part of the cold air flowing through the circulation path 21 of the vending machine 10 is sucked into the cooling unit 71 via the air guiding unit 91.
The cold air sucked into the cooling unit 71 is discharged to the outside of the temperature control system 1 by the cooling fan 71a via the resistance unit 73 and the air discharge unit 92.

This makes it possible to discharge a part of the cold air from the vending machine 10 to the outside and cool the outside of the vending machine 10.

That is, in the present embodiment, when the power supply from the commercial power source is interrupted due to a power outage or the like, the power supply from the generator 50 housed in the generator storage rack 60 adjacent to the vending machine 10 causes the vending machine. It becomes possible to maintain the operation of 10.
Further, by sucking from the load test device 70 housed in the generator storage rack 60, it becomes possible to supply the cold air inside the vending machine 10 to the outside.

(Another form of arrangement of the load test device 70)
In the present embodiment, the air guide unit 91 communicating with the vending machine 10 is attached to the intake port of the cooling unit 71 of the load test device 70, and the other opens to the exhaust port of the resistance unit 73 of the load test device 70. The mode in which the air discharge portion 92 is attached has been described.
However, the air guide unit 91 may be attached to the exhaust port of the resistance unit 73 of the load test device 70, and the air discharge unit 92 may be attached to the intake port of the cooling unit of the load test device 70.
In this case, the cooling fan 71a rotates in the reverse direction so that the air flows in the direction opposite to the case where the cooling air is sent to the normal resistance portion 73 because the cooling air of the vending machine 10 is sucked.

(Another form that discharges cold air to the outside)
Further, in the present embodiment, the embodiment in which the load test device 70 sucks in the cold air of the vending machine 10 and discharges it to the outside has been described.
However, the load test device 70 may send air to the vending machine 10, and a part of the cold air of the vending machine 10 may be discharged to the outside from the take-out port 17.
In this case, since the air from the outside flows into the circulation path 21, the flow rate of the cold air inside the vending machine 10 increases, and the cooling capacity of the temperature adjusting unit 11 can be increased.

Further, in the present embodiment, an example is shown in which an air guide unit 91 is attached to the back wall 62 of the generator storage rack 60 and an air discharge unit 92 is provided in front of the generator storage rack 60, but these are generator storage. It may be provided on the upper surface wall or the side wall of the rack 60.
