BACKGROUND

1. Technical Field

The present disclosure relates to an oxygen content adjustment apparatus and a container data center including the oxygen content adjustment apparatus.

2. Description of Related Art

For most humans, a comfortable range for oxygen content of breathable air is about 17%-21% range. Discomfort occurs when the oxygen content is between 14%-17%, this discomfort becomes a physical hazard when the oxygen content is lower than 14%. To make an enclosed space such as a container data center habitable, the oxygen content therein is controlled to be between 17%-21% of the ambient air. However, when the enclosed space is unoccupied, it is needless to have the oxygen content at the higher percentage and importantly the higher oxygen content of the ambient air will sustain a fire. Therefore, there is room for improvement in the art.

BRIEF SUMMARY OF THE INVENTION

An embodiment of an oxygen content adjustment apparatus includes an oxygen content detector, a plurality of keys, a controller, an oxygen source, a first nozzle, a first valve, a flame retardant gas source, a second nozzle, and a second valve. The oxygen content detector detects oxygen content in a container data center and issuing a first detection result. The keys regulate oxygen content in environment inside the container data center. The controller is electrically connected to the oxygen content detector and the keys. The oxygen source stores oxygen. The first valve is connected between the oxygen source and the first nozzle. The first valve includes a control terminal electrically connected to the controller for controlling open or closing of the first valve. The flame retardant gas source stores flame retardant gas. The second valve includes a control terminal connected to the controller. The second valve is further connected to the flame retardant as source and the second nozzle.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawing, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to the FIGURE, an exemplary embodiment of an oxygen content adjustment apparatus100includes an oxygen content detector10, an air pressure detector20, a controller30, three keys32,34, and36, an oxygen source40, a first valve50, a first nozzle60, a flame retardant gas source70, a second valve80, a second nozzle90, and a gate110. The oxygen content adjustment apparatus100is mounted in a container data center.

The oxygen content detector10detects the oxygen content in the environment, and issues a first detection result.

The controller30is electrically connected to the oxygen content detector10, the air pressure detector20, and the keys32,34, and36. The controller30is also electrically connected to control terminals of the first valve50and the second valve80, and electrically connected to a control terminal of the gate110. The gate110equalizes the air pressure inside the container data center and the outside air pressure.

The first valve50is connected between the oxygen source40and the first nozzle60. The controller30controls opening or closing of the first valve50.

The second valve80is connected between the flame retardant gas source708and the second nozzle90. The controller30controls opening or closing of the second valve80.

The oxygen source40stores oxygen. The flame retardant gas source70stores flame-retardant gas, such as nitrogen, carbon dioxide, or heptafluoropropane.

When a person is in the container data center, the person presses the key32, and the key32is activated. The oxygen content detector10detects the oxygen content in the environment and issues the first detection result to the controller30, which determines whether the oxygen content is within a 17%-21% range. The controller30directs the first valve50to connect the oxygen source40to the first nozzle60if the oxygen content is below 17%. The oxygen of the oxygen source40flows into the environment. At the same time, the oxygen content detector10continually detects the oxygen content in the environment. The controller30directs the first valve50to disconnect the oxygen source40from the first nozzle60if the oxygen content exceeds 17%.

When the last person leaves the container data center, he or she presses the key36, and the key36is activated. The oxygen content detector10monitors whether the oxygen content in the environment is below 14% and issues the first detection result to the controller30. The controller30directs the second valve80to connect the flame retardant gas source70to the second nozzle90if the oxygen content exceeds 14%. The flame retardant gas of the flame retardant gas source70flows into the container data center. At the same time, the oxygen content detector10continually detects the oxygen content in the environment. The controller30directs the second valve80to disconnect the flame retardant gas source70from the second nozzle90if the oxygen content is less than 14%.

When the person will to be in the container data center for only a short time, he or she presses the key34, and the key34is activated. The oxygen content detector10monitors whether the oxygen content in the container data center is within a 14%-17% range and issues the first detection result to the controller30.

The controller30directs the second valve80to connect the flame retardant gas source70to the second nozzle90if the oxygen content exceeds 17%. The flame retardant gas of the flame retardant gas source70flows into the container data center. At the same time, the oxygen content detector10continually detects the oxygen content in the environment. The controller30directs the second valve80to disconnect the flame retardant gas source70from the second nozzle90if the oxygen content is less than 17%.

The controller30directs the first valve50to connect the oxygen source40to the first nozzle60if the oxygen content is less than 14%. The oxygen of the oxygen source40flows into the container data center. At the same time, the oxygen content detector10continually detects the oxygen content in the environment. The controller30directs the first valve50to disconnect the oxygen source40from the first nozzle60if the oxygen content exceeds 14%.

The air pressure detector20detects air pressure in the environment and issues a second detection result to the controller30. The controller30directs the gate110to open if the air pressure in the environment exceeds a predetermined valve.
