Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to power equipment designed to improve the reliability of an air conditioner that cools a plurality of containers containing electrical equipment. [Prior Art] Figures PJ3 and 4 are plan views showing conventional air conditioners for power equipment housing electric equipment.

First, Figure 3 shows an air conditioning system called the central system, where 9, fi+ is a hallway, (2) is a door, and (2) is a door.

In addition, in FIG. 4, for example, regarding the container (3a), one of the two indoor units (8) placed indoors.
The container (3a) can be cooled by the stand. The remaining one is a backup machine in case this one breaks down. Other containers (3b) - (
A similar operation can be performed for 3d).

[Problem that the invention seeks to solve]

As mentioned above, the conventional air conditioner is the central type shown in Figure 3, which requires additional power equipment.

It was not easy to cope with the increase and decrease of 9 containers due to the change,
The problem was that the capacity of the indoor unit (8) and outdoor unit (9) of the near conditioner had to be changed, the size of the ventilation duct (41) had to be changed, and the size of the air conditioner room α had to be changed. The same applies to the central system shown in Figure 3, but in the individual system shown in Figure 4, there is only one set of spare near conditioners for each container, so the spare machine is also A frequent problem was that in the event of a breakdown, the electrical equipment in the container had to be shut down.

This invention was made to solve the above-mentioned problems, and can easily cope with the increase and decrease of containers.

In addition, it is an object of the present invention to obtain power equipment equipped with an air conditioner that has a long hole length as a whole and is difficult to cause system failure, by having another normal near conditioner compensate for the failure of a near conditioner.

[Means for solving problems]

The power equipment according to the present invention is provided with a container housing electrical equipment and a storage chamber through which gas can flow, and the outputs of a plurality of air conditioners are stored in the storage chamber.

[For production]

In this invention, by storing the output of a plurality of air conditioners in a storage chamber and supplying air from this storage chamber to each container, even if one or more air conditioners fail, the entire air conditioner [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. No. [
In the figure and FIG. 2, (1) to (IG) are the same as the above-mentioned conventional device. (111 is an indoor unit (8) of eight near conditioners with the same capacity installed on the top of the F111. filter with an air chamber that commonly connects the outlet sides of the

), the total cooling capacity of each container (3a) to (3
d) shall be greater than the total value of the maximum cooling load.

In the power equipment configured as described above.

The air cooled by the near conditioner +81 (9) is blown to each container (3a) to (3d) via the common air chamber U and the ventilation duct (4), and the air is blown to each container (3a) to (3d) through the air outlet +5.
1, it is blown into the room. The blown air flows into each container (
After cooling 3a) to (3d), open from the door grill.
Return to F l+, where they are mixed with each other and sucked into the indoor unit (8), and the 8 near conditioners + 81 (for 91,
During cooling loads, multiple units will perform cooling operations, but
Based on the temperature of the return air obtained by a sensor installed in the hallway, a number-of-units control operation is performed for cooling operations according to increases and decreases in the cooling load. However, the minimum number of blower fans in the indoor unit (8) is set and operated at all times, regardless of the size of the cooling load.

In addition, regarding the operating order of the indoor unit (8) air blower fan and the outdoor unit (9) compressor of each near conditioner, in order to equalize the degree of wear and tear, the operating order is changed at certain time intervals. Good too.

The air chatter damper port is for preventing air from flowing back into the hallway (1) from the common chamber αD inside the stopped indoor unit (8).

In addition, if you want to adjust the amount of air blown to each chamber according to the cooling load and set temperature of each container (3s to 3d), use the air volume adjustment damper (6), which is installed in each air duct. The electric heater was controlled by the room temperature thermostat in each container, and the electric heater was controlled by the room temperature thermostat in each container.

In addition, if a near conditioner fails, the entire air conditioner operates as if it does not exist, so even if one or more units fail, normal operation can be carried out. Even if the buoyancy increases, it is possible to continue cooling each container by reducing it from the rated buoyancy at the time of design.

Furthermore, as is clear from Fig. 1, it is easy to expand or contract the power equipment in the longitudinal direction of the second corridor F. For example, if there are no containers (3a) and (3C), the near conditioner can be Reduced from one to four.

Common air chats can also be reduced to half their length.

In the above embodiment, a case was described in which a ventilation duct was provided in each container, but no duct was used.

Air may be blown from the upper part of each chamber using a blow-off nozzle.

Furthermore, as an air conditioner, it is not a near conditioner;
It may be another cooling device or heating device, and its capacity is not necessarily required, since if it breaks down, the capacity of the electrical equipment may be lowered. It doesn't have to be more than your ability.

〔Effect of the invention〕

In this invention, a container housing electrical equipment and a storage chamber through which gas can flow are provided, and the output of a plurality of air conditioners is stored in the storage chamber, and air is sent from the storage chamber to each container. Alternatively, even if multiple air conditioners break down, system failure of the air conditioners can be prevented.
