Dehumidication system for server room and home use

Dehumidification is the process of eliminating water vapour from the air. Dehumidification is a critical step in protecting your health and preserving your property. Dehumidifying equipment can assist in reducing excessive humidity. Several typical problems associated with excessive humidity include the following:

Metal surfaces corrode. This is a regular occurrence in cities along the seacoast. Corrosion protection of electrical equipment and the ship's body is a significant concern in marine engineering.

Electronic equipment failure. It is critical to maintain adequate humidity levels in server rooms, data centres, and telecom rooms. Excessive humidity can result in the formation of water drops on electronics cards owing to condensation, while low humidity might contribute to the development of static charges.

Fungi and moulds on walls, food, and other surfaces. This is a frequent occurrence in homes near the sea or in indoor swimming pools. High humidity levels might be harmful to your health.

Condensation and moisture can result in a variety of problems, ranging from damp patches on walls to damaged clothing to damage to electronic and digital equipment such as dvd players and plasma televisions. A dehumidifier can easily resolve the issue. Excessive moisture tends to generate water on the floors and walls, making them extremely slippery and prone to human fall. By removing excess moisture using a dehumidifier, you may significantly reduce mould spores and house mites. The presence of moisture in the air might be detrimental to one's health. It may predispose you to rheumatoid arthritis and rheumatoid rheumatism. Additionally, current study indicates that increased humidity promotes the growth of house-mites, which raises the risk of asthma episodes. This can be remedied by the use of a dehumidifier.

Dehumidifiers are classified into two categories based on the technology used to dehumidify them: refrigerant-type dehumidifiers and mechanical dehumidifiers.

The following tutorial details how to modify the strategy of air-handling controls in a data centre so that they operate within the ASHRAE recommended range while saving energy on cooling and humidification. This means that the outside air handler is not responsible for controlling moisture.

  1. Reducing the amount of fresh air supplied to the computer room while maintaining a minimal level of pressurisation and ventilation.
  2. Determine the temperature of the air entering the information technology device.
  3. Resolve each hot spot (which affects the air that enters other IT equipment) by bleaching the plates, relocating the floor gratings, and removing the racks' glass doors, among other things.
  4. Increase the air handlers' setpoints. Increase the set point of the return air if possible, but ensure that the air supply to the IT equipment remains within the ASHRAE recommended limits (18 ° C / 64.4 ° F 27 ° C / 80.6 ° F ). Ideally, the control strategy should be changed from CRAC return air to supply air control to ensure that a constant air temperature is maintained.
  5. The next step is to change the air handlers' relative humidity setpoints. It should be kept above 5.5 ° C / 41.9 ° F dew point air for humidification (DP). This is accomplished by aligning the set point with the return air setpoint relative humidity (RH) at the following temperatures: 24 ° C / 75.2 ° F (30 percent RH), 26 ° C / 78.8 ° F (27% RH), 28 ° C / 82.4 ° F (24% RH), 30 ° C / 86 ° F (21% RH), and 32 ° C / 89.6 ° F (21% RH) (19 percent RH). Bear in mind that these HR set points are far lower than those often utilised in conventional buildings, but still fall within the ASHRAE suggested range.
  6. To dehumidify, the dew point must be below 15 degrees Celsius / 59 degrees Fahrenheit (for temperatures, air-supplied IT equipment between 23 degrees Celsius / 74.4 degrees Fahrenheit and 27 degrees Celsius / 80.6 degrees Fahrenheit). Because the dew point of the device (ADP) is often well below these values in most refrigeration systems, the necessary dehumidification will occur in the battery cooling air handler. As a result, there is typically no additional activity required to have distinct trays and condensate pipework in air handlers.
  7. However, if an external source of humidification is required due to high humidity, the relative humidity should be regulated according to the return temperature to maintain the dew point below 15 ° C / 59 ° F as follows: 24 ° C / 75.2 ° F (57 percent RH), 26 ° C / 78.8 ° F (51 percent RH), 28 ° C / 82.4 ° F (45 percent RH), 30 ° C / 86 ° (36 percent RH).
  8. You should monitor the temperature of the dry bulb and the dew point of the entering air to the IT equipment on a regular basis.

For decades, we've maintained relative humidity levels of 45 to 50% in data centres, assuming that high humidity is necessary to minimise static discharge problems. That is no longer the case.

According to a 2014 research study commissioned by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) technical committee TC 9.9, the danger to IT equipment from static generation and discharge in the data centre environment is negligible at 15% relative humidity (RH), and can be reduced to 8% RH with only minor precautions (Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment). That data centre humidity revelation can assist you in reducing energy use and increasing your power usage effectiveness ratio, or PUE.

If you run your data center's equipment at higher intake temperatures in compliance with the 2008 and 2011 ASHRAE Thermal Guidelines, maintaining a high relative humidity needs significant moisture addition; heated air contains more water vapour than cool air. Using unnecessary water and energy to humidify the data centre is incompatible with current green practises.

According to the Uptime Institute's newest survey, almost one in five racks had a density of 30 kilowatts (kW) or greater, demonstrating the expanding prominence of high density computing. The majority of respondents said that their current rack density was between 10 and 29 kW. On an individual server level, the majority are set to operate at a maximum of 600 watts.

Sorbents are solid or liquid compounds that remove and retain other substances (often water vapour) when they come into contact with them.

Sorbents fall into two broad types.

— Adsorbents

Asorbent is a substance that undergoes physical, chemical, or both changes during the sorption process. Lithium Chloride is an example of an absorbent that is solid. When this material absorbs water, it becomes hydrated. The air is passed through sprays of a liquid sorbent such as lithium chloride or glycol solution in a liquid sorption dehumidification system.

When activated, the sorbent has a vapour pressure lower than that of the dehumidified air and collects moisture from the air stream. During the absorption phase, the sorbent solution becomes diluted with moisture, which is then given up to a hot air stream during regeneration.

Typically, lithium chloride is employed as an absorbent, either in liquid form or as solid crystals in a honeycomb shell.

Adsorbent : A sorbent that remains physically and chemically unchanged during the sorption process. Adsorbents are often granular beads or solids having porous features that enable them to store a significant amount of water on their surface.

Desiccant dehumidification works on the idea of exposing the desiccant to moisture-laden air and extracting the moisture. Heat is applied to the saturated desiccant, which evaporates the moisture gathered into the exhaust air stream. The desiccant has been regenerated and is ready for use.

Thus, it is possible to establish a continuous cycle of sorption and regeneration, resulting in extremely low dew points. Silica gel, Molecular Sieve, and Activated Alumina are all examples of absorbents that are frequently utilised.

Knowing the rate at which an object cools down is a useful tool in any research experiment. While the process can be lengthy, the more precise the data collected, the more precise the outcomes. Additionally, graphing the cooling rate on graph paper can assist you in visualising and explaining the process.

Take note of the room temperature of the item for which the cooling rate will be determined.

Significantly heat the object, almost twice the room temperature if possible.

Take a temperature reading soon after turning off the heat source.

Every minute, take the temperature of the item and record it. Continue recording temps until the object reaches its initial room temperature.

Construct a graph using the results on graph paper. On the X and Y axes, plot temperature versus time.

Plot the results on the graph and connect the dots to create a cooling rate curve line.

Calculate the cooling rate by dividing each temperature data point by its corresponding time data point and then averaging your responses to obtain a cooling rate. In other words, the temperature change divided by the time change yields the average temperature rate change.

The term "relative humidity" refers to the difference between the amount of moisture in the air at a certain temperature and the maximum amount of moisture the air can hold at that temperature. Maintaining ambient relative humidity levels between 45 and 55% in a data centre or computer room is suggested for best performance and dependability.

When relative humidity levels become excessive, water condensation can develop, resulting in hardware corrosion and premature system and component failure. When the relative humidity level is too low, computer equipment becomes prone to electrostatic discharge (ESD), which can harm sensitive components. When monitoring the data center's relative humidity, we recommend setting early warning alerts at 40% and 60% relative humidity, and critical alerts at 30% and 70% relative humidity. It's crucial to remember that relative humidity is proportional to the present temperature, making it critical to monitor both temperature and humidity simultaneously. Risk and associated expenses can grow exponentially as the value of IT equipment increases.

When temps fall below 50°F and rise over 82°F, your server begins to fail. A server failure might put your business's operations on wait for several days, if not a week. As a result, it's critical to understand the warning signals that your server is likely to collapse. These include the following:

  1. Reboots on an ongoing basis
  2. Unpredictable server failures
  3. Computers that run slowly
  4. Services are ineffective.

A deliberate approach to server room cooling is required. If you require assistance with cooling your server room, contact an expert such as Heinz Mechanical. We provide computer room air conditioning units that are energy efficient and ensure the safety and operation of your equipment.

While we are all aware of the importance of humidity to our skin, hair, and overall health, did you realise that it is also critical to the health of our homes? If the humidity level in your home falls too low, your furnishings and residence may decay and some viruses will flourish. Let's discuss the humidity levels you should maintain year-round in your home and the many strategies for doing so.

The ideal humidity level in the home should be around 45 percent. Anything less than 30% is considered too dry, and anything over than 50% is considered excessive.

When an object is heated, its temperature increases proportionately to the amount of heat applied. The increase in temperature is referred to as sensible heat. Similarly, when an object's heat is removed and its temperature decreases, the heat removed is likewise referred to as sensible heat. Sensible heat is heat that causes a change in the temperature of an object.

Maintaining a server room's temperature is a difficult task. Due to the fact that servers generate heat, you must establish a cool environment while also using fans to disperse the heat away from the servers.

If you are in charge of this difficult work, you actually hold the life of those servers in your hands. If the right temperature is not maintained, permanent damage can occur.

Graphics cards have the potential to catch fire.

It is not uncommon for customers to report graphics cards catching fire due to excessive heat. The same thing can happen in your server room if the temperature rises too high.

Overheated servers might cause the CPU to fail.

CPUs are brittle and are frequently the first component to fail. When the CPU melts due to excessive heat, the server is toast. This consequence of a failed CPU is instantly obvious, as a server cannot run without a functioning processor.

While you can replace the CPU, the memory, motherboard, and power supply will have been irreversibly compromised due to heat exposure. This means that certain components will fail sooner than anticipated, assuming they weren't already burned by the CPU.

Memory of a programme can become corrupt.

As the temperature rises, ROM memories that are dependent on a charged, isolated plate will lose memory. When this occurs, the memory of the application can get corrupted.

Programs can begin to malfunction.

As thermal noise grows, a larger bit error rate may occur, resulting in programmes misinterpreting commands. At this stage, programmes may begin to behave erratically, and the entire server may reboot for no apparent reason.

Fans and compressed air alone are insufficient; a liquid cooling system is required.

If your server room does not have an ice cold temperature, it is not cold enough. While fans are necessary, they cannot bring the temperature down to the level of a computer room cooling system.

To safeguard your servers, you must regulate the room's temperature and air flow to avoid hot areas. Additionally, you must filter the air to prevent particulates from damaging the machinery. This is possible with the aid of a computer room air conditioner.

Historically, a computer room air conditioner (CRAC) has been an excellent technique to maintain exact temperature and humidity control in a server room. A CRAC system cools the air using a compressor, but liquid cooling is gaining traction. Indeed, Alphabet, Google's parent firm, was forced to use liquid cooling to cool its powerful TensorFlow 3.0 AI computers.

There is a worry with fluids in a server room where lines may need to be severed and rejoined. However, the cooling fluid is dielectric, and manufacturers are designing non-drip modular couplers for liquid cooling systems. Couplers used in low-pressure liquid cooling systems are comparable to those used in agriculture and industrial machinery.

Anyone can use liquid cooling.

A liquid cooling system does not require a large budget. Although it will cost money to power the system. However, if you rely on your servers, the expense is justified. To begin, liquid cooling systems are more efficient than forced air cooling systems. You will pay slightly more for energy use, but the outcome will be a cool server room free of hot spots that could harm or destroy your servers.

If you're inquisitive about the options, there are several startups that sell various types of liquid cooling systems. For instance, one method makes advantage of a low flow rate and negative pressure. When a line is broken, the fluid retreats rather than spills out.

Another cooling method allows for the purposeful spillage of small amounts of coolant onto the CPU and RAM to further cool the components. It is not a concern because this liquid is non-corrosive, non-flammable, and dielectric.

Certain liquid cooling systems cannot be simply retrofitted onto operational servers. Special mounting and configuration are required.

Are you unable to use liquid cooling? Continue to use compressed air.

If you are unable to retrofit your existing server room with a liquid cooling system, a compressed air system is still the ideal alternative. It makes no difference which system you use as long as the server room remains cold.
