[0009] BACKGROUND OF THE INVENTION

[0010] Field of the Invention. The present disclosure relates generally to data center equipment and more specifically relates to a humidification system for use in data centers.

[0011] Description of the Related Art. Some equipment in a data center may prefer certain levels of humidity. It is well understood that a typical refrigeration cycle, often used to provide cooling air to a data center, can reduce humidity. Humidity dropping below a preferred humidity can be problematic and may reduce heat transfer from heat sources within the data center. [0012] The use of electricity to add water to the airstream of a data center can have a negative impact on power usage effectiveness (PUE) and the overall efficiency. The addition of water via electric humidification is often done using the cooled air stream. This method is inefficient due to the low mass ratio that can be applied to the already cool air which is often 20-30 degrees Fahrenheit below the dry-bulb temperature of the area in concern. There are also issues that arise from the possibility of water droplets in ducts. This often requires controls modification during the process.

[0013] A need exists in the art for improved humidification in data centers. [0014] BRIEF SUMMARY OF THE INVENTION

[0015] Applicants have created new and useful devices, systems and methods for humidification of data centers.

[0016] In at least one embodiment, a data center humidification system can include a housing having an inlet for receiving warm air and an outlet for ejecting humid air, an inlet wetted media within the housing near the inlet, an outlet droplet trapping media within the housing near the outlet, and a fan within the housing and configured to move air through the housing. In at least one embodiment, the data center humidification system can include a liquid delivery pipe to deliver liquid to the inlet wetted media.

[0017] In at least one embodiment, the housing can be mounted to or within a server cabinet. In at least one embodiment, the housing can be less than 74 inches tall, less than 21 inches wide, and less than 44 inches deep. In at least one embodiment, the data center humidification system can include two, three, or more fans within the housing. The fan(s) can provide an air velocity within the housing of over 500 feet per minute (FPM). [0018] In at least one embodiment, the data center humidification system can include a secondary wetted media within the housing between the inlet wetted media and the outlet droplet trapping media. In at least one embodiment, the secondary wetted media can be spaced apart from the inlet wetted media, such as by between 2 inches and 5 inches. In at least one embodiment, the data center humidification system can include a secondary delivery pipe at least partially within the housing and configured to deliver liquid to the secondary wetted media.

[0019] In at least one embodiment, the data center humidification system can include a first outlet droplet trapping media and a second outlet droplet trapping media.

[0021] In at least one embodiment, the data center humidification system can include a controller to monitor and/or control aspects of the data center humidification system. For example, in at least one embodiment, the controller can monitor pressure, temperature, and/or humidity at the inlet and/or outlet of the housing.

[0065] It can be seen that the data center humidification systems 100 of the present disclosure can be mounted in a cabinet 200 next to other cabinets 200 containing servers 202. In at least one embodiment, the data center humidification systems 100 of the present disclosure can be mounted in a cabinet 200 containing servers 202. In at least one embodiment, the data center humidification systems 100 of the present disclosure can be mounted in a cabinet 200 containing servers 202 below those servers 202. In at least one embodiment, the data center humidification systems 100 of the present disclosure can be mounted in a cabinet 200 containing servers 202 above those servers 202. In at least one embodiment, the data center humidification systems 100 of the present disclosure can be mounted in a cabinet 200 containing servers 202 between those servers 202.

[0066] It can be seen that the data center humidification systems of the present disclosure can use heat from the servers to humidify the air, rather than additional heat sources, which can be more efficient than conventional systems and can provide high levels of localized cooling. By using the heat from the servers, the data center humidification systems of the present disclosure require less fan energy and less air velocity to evaporate the water. By locating humidification near the point of use, such as near the servers, the data center humidification systems of the present disclosure reduce water waste and reduce condensing requirements of perimeter units. By not attempting to humidify the cooling air, from the cooling unit, there can be less risk of condensation in ducts and/or under floors.
