Why Air Conditioners Are Necessary For Server Rooms

Rooms with computer servers require adequate cooling to keep the room temperature cool and prevent it from excess heating.

Consistent overheating can damage your equipment beyond repair. Your business operations may be disrupted entirely without a functioning room in addition to the hefty replacement cost.

As the backbone of your network infrastructure, they must continue to operate smoothly. That is why buying effective and efficient air conditioners are not a matter of if, but when.

How To Choose An Air Conditioner For Server Rooms

Coverage Area

One of the most important factors that you need to consider before making a purchase is the server room’s coverage area. The type of AC you need to buy depends on the room size and the amount of heat generated. You can utilize an air conditioner BTU calculator for server room to know how many BTUs you need.

However, to give you an understanding, here’re a few recommended coverage areas with appropriate cooling capacities:

  • 2000 BTU for less than 100 sq ft
  • 6000 BTU for 150-200 sq ft
  • 8000 BTU for 300-350 sq ft
  • 15000+ BTU for 700-1000 sq ft
Installation Requirements

Typically, air conditioners – whether ductless, portable, or window-mounted – vent their hot/warm air while cooling the indoors. The air vents out using the unit’s exhaust hose and can be released through the window, ceiling, wall, or the server room’s sliding glass doors.

It is crucial to ensure that whatever outlet you use to vent out air is vacuum-sealed to protect the machinery’s integrity. These units also come in dual or single-hose to provide effective cooling by venting warm air produced by the servers and drawing fresh air insides to cool.

Additionally, if the air conditioner has a dehumidifying feature, you also need to consider how it deals with the moisture build-up. Different air conditioning units have various methods to deal with moisture, such as fully evaporative, partially evaporative, drain hose, condensate pipe, or buckets.

Besides that, you need to make sure the power system you have meets the unit’s needs. Generally, AC systems that have a cooling capacity below 15000 BTU functions on a 120v circuit. On the contrary, large AC units, such as central air conditioning models, come with a cooling capacity above 15000 BTU require a circuit around the 230-240v range.

Portability

Portability includes many variables, such as weight and server room air conditioner sizing. You need to move the AC to where it’s needed the most (rack servers).

Mobility also allows you to prevent the AC from leaking water on the floor and around the equipment. When looking for a small portable AC, remember to check for wheels on the model you are considering.

Energy Efficiency Rating (EER)

Energy Efficiency Rating (EER) is the measurement of an air conditioner’s energy efficiency level. A higher efficiency level means the device uses less energy. In other words, the higher the EER rating of AC models, the more energy you save.

What’s significant to bear in mind is that the EER ratings measure an air conditioner’s efficiency at the one standardized operating temperature, i.e., 95°F.

Generally, an AC with a 12 EER or higher is considered energy efficient. Thus, always aim for a higher EER rating AC to ensure adequate cooling in less power.

Noise Levels (dBA)

Irrespective of which type of air conditioning system you use, all air conditioners produce a little sound. Wall-mounted, ceiling-mounted, spot cooling, or commercial grade – they do make some noise while operating.

Although there are many options when it comes to quiet portable ACs, they can sometimes emit a recurring sound that the model generates is often termed as background noise. This noise is easy to ignore when the AC is new, but it increases as it depreciates.

This noise level is measured in decibels. Typically, any AC unit within the range of 50 to 60 decibels is quiet enough for everyday usage.

Air Filters

Air filtration is a key function of every air conditioner. This technology is responsible for removing dust, dirt, odor, allergens, mold, and bacteria from the room to ensure clean, cool, and fresh air.

There are several different types of air filters used in air conditioners. Some of the widely used types include washable or reusable filters (stronger cloth-based material and relatively cheap), fiberglass filters (can only be used once), or pleated filters (polyester material).

Normally, AC air filters are equipped with a self-clean function that keeps it dust-free on the inside. This further helps it provides optimal performance.

Performance Features

Here are some performance features you should also look for in your AC:

  • Sleep mode: It’s an energy-efficient, quieter operating mode for your sleep hours
  • Multiple Fan speed: Select from various fan speeds: high, medium, or low
  • Auto-setting: Allows you to set a default room temperature
  • Remote control operation: It allows you to set and monitor the room temperature and also select preferred operating modes through a hand-held remote or a smartphone application
  • Dehumidifier: This ensures an optimal level of moisture in the room
  • Timer settings: Set time limits for the machine to start or stop at predefined intervals
  • Warranty: A warranty assures that you can exchange or repair the air conditioner if need be. The normal warranty period of an AC unit ranges anywhere from 2 years to 7 years.
Price Vs. Budget

Lastly, you may want to consider the price of the air conditioner you intend to buy and your budget.

There are various air conditioning systems available in the market that can effectively cater to your server room’s cooling requirements. You can find an efficient AC for anywhere between $500 to $9000.

However, you need to keep in mind that an air conditioner’s price will vary according to the number of features, its cooling capacity, and the room size. Thus, it is important to consider these elements before making a purchase.

How Much Cooling Is Needed For Server Rooms And Data Centers?

You need to consider many factors to calculate air conditioner size for server room and data centers. Believe it or not, sizing a server room air conditioner is crucial if you want proper cooling and functional equipment. These factors are:

  • The Size Of The Room:
    To calculate room area in m2, apply this formula: room size BTU = length x width x 337
  • The Size Of The Windows:
    If there is any (total windows BTU = North windows + South windows)
  • The Number Of People Working In The Room (If Any):
    Normally, the heat produced by a single person is 400 BTU. Therefore the equation is: Total number of occupants (BTU) = number of people x 400
  • Add up the servers, routers, switches, and other equipment wattages and then multiple it by 3.5.
    The equation can be: Total Equipment BTU = Total wattages x 3.5
  • Also, add up the total lighting wattages and multiply it by 4.25.
    Hence the equation is: Total lighting (BTU) = total lighting wattages x 4.25

Once you have all the BTUs, add them up or place them into a server room AC calculator. This way, you will know how much cooling capacity is required for the room and data center.

Types of Cooling Systems For Server Rooms

There are various air conditioning systems that you can choose from based on the size and the amount of heat produced in your room.

Spot Cooling AC Systems

Spot cooling AC systems are highly desirable for small server rooms. These portable ACs can be put close to the rack servers, closets, or any other place where it is needed most.

You should choose it if you want to cool high-priority small server rooms in a shorter period.

Wall Mounted AC Units

Wall-mounted ACs are another popular type that you can opt for, especially if you have medium-to-large server rooms.

Also known as ductless, mini-split air conditioners – these units deliver server rooms with easy, uniform,  and most-efficient cooling without any added hassle or expense.

Ceiling/Cassette ACs

Another type of cooling system you can choose for the server room is the ceiling/cassette air conditioning system. What’s unique about this system is that it’s mounted on the server room’s ceiling instead of the floor or wall.

Many IT professionals prefer this type of cooling system for their server rooms since they don’t acquire any floor space and provide adequate cooling for the entire room.

Commercial Grade AC Units

Commercial Grade air conditioners are some of the most popular cooling systems for server rooms and other high-demand commercial uses. Not only do they provide sufficient cooling, but they also offer heating and dehumidification, which can improve servers’ performance and efficiency.

Liebert’s Mini Mate and PDX are some of the most sought-after commercial grades ACs because they provide increased cooling with dehumidification and air filtration.

Consider them and other Liebert server room AC units if you want instant cooling.
