New server room air conditioning system for Saga Healthcare

New server room air conditioning system for Saga Healthcare Stafford

 
Orion air conditioning is has completed the installation of a server room air conditioning system for Saga Healthcare in Stafford. The new server room was for the expansion of the companies ongoing quality services for the over 50's. The state of the art server room had a humidification system and high quality Mitsubishi Electric air conditioning system to maintain temperature and humidity levels. All pipe services were run on the sides of the room to avoid any case of water leaks on to important equipment.
Mitsubishi Electric air conditioning units are renowned for long reliable life span and are ideal for server rooms and Com's rooms were a failure can mean the complete shut down of an entire business or at worst server damage. The new units are energy efficient inverter systems which have a high COP and modulated inverter compressor which can save up to 40% on server room air conditioning that can run 24 hours / 7 days a week. On a recent installation powered off a UPS system, existing fixed speed (non inverter) server room air conditioning systems were using 35% of the UPS rated power output. When new inverter systems were installed the power being used was 7%. Inverters have a massive energy saving potential.

What air conditioning units were installed at Saga Healthcare Stafford:

6 x  Mitsubishi Electric Air Conditioning Power Inverter Mr Slim PKA-RP100KAL (10kW / 33000 Btu) which provided enough cooling for the 85 meter square area, 8  server racks and  2 100KVA UPS systems within the server room with spare cooling capacity in case of failures and future expansion. With all wall air conditioning units instead of ceiling cassette air conditioning was a safer option because when air conditioning unit fails they tend to leak water. If the water leaks out of a ceiling cassette it can drip into the top of important server equipment, with wall air conditioning units this limits the leakage to the sides of the room. These Mitsubishi PKA-RP100KAL can be found worldwide and have a amazing COP (3.61 x initial electrical input) which means that every 1000w of electrical energy going in produces 3610 watts of cooling.

Server room air conditioning efficiency and CO2 emissions:

This air conditioning system, because oversized for the area meant we had spare capacity in case of any failure on any of the systems. The clients servers held critical medical data relating patients so could never fail. The bonus of the extra capacity was that the systems ticked over at sub 50% capacity and the outdoor inverter units slowed down because the temperature had been reached, therefore just pumping small amounts of cooling energy in to maintain the server room. The energy saving was phenomenal and CO2 emissions significantly improved.

Why use a Vapac humidifier for your Server room:

The Vapac humidifier is another world renowned product for reliable and safe production of humidity for server rooms, this is ideal when air conditioning is being used as it counter acts  the drying affect air conditioning tends to have on a area. The Vapac unit can be controlled by a humidistat which gives you the option of setting the actual humidity percentage for a particular application. For server rooms there are two reasons why you should have humidity control. Firstly ASHRAE’s "Design Considerations for Data and Communications Equipment Centres" recommends relative humidity conditions between 40% and 55%, with an allowable level between 20% and 80%. If a server room has a very low humidity the chance of static can rise to problem levels even with earth strips installed. Secondly if the server room is habitated by personnel the affect of dry air sub 20% is detrimental to health, skin and eyes.
Power / Heat-Loss Summery:
Server room efficiency: 85% approximately 
Total power of servers: 80000 Watts
Total heat loss: 6550 Watts@85% +/-
Room in Square Meters: 10625 Watts
Total Heat Load: 17175 Watts
Key points to think about when getting air conditioning for server rooms:
  • Use inverter air conditioning as it will save energy in the long run.
  • Always follow the ASHRAE’s Design considerations for data and communications equipment centres guidelines towards humidity
  • Cheap air conditioning units do not work in cold weather because they do not have a outside fan speed controller (low ambient kit)
  • Use a established brand so if a part fails on you Server room air conditioning you are not waiting 8 weeks for a spare part.
  • Sometimes it is worth having two server room air conditioning units because if one fails you still have some cooling.
  • To establish the heat load of you servers add up all the power supplies of your servers rack and assume a 40% loss to heat. i.e- If you have 10 servers with 400watt power supply the total watts will be 4000 watts. assuming a 40% loss the heat load will be 1600 watts.
  • Work on a average watts per/Msq of 125watts, so if you server room is 5 x 5 meters you will require a base of 3.5kw/12000btu + the heat load.
  • Advised manufactures for server room air conditioning Mitsubishi, Daikin, Fujitsu and Lg
  • Always use auto-restart units for server room air conditioning units as power failures can shut budget air conditioning down.
  • If your server room is temporary (ie short term lease on building) or has building restrictions then portable air conditioning maybe your only option.
  • If using portable air conditioning for your server room then make sure it recycles the water for better cooling performance of that it has a integral condensate pump.
  • Use a established business who will not be going out of business for your server room air conditioning installation as the warranty of the air conditioning is with the supplier not the manufacturer.

Fujitsu Wall mounted air conditioning units are often used in Domestic Air Conditioning Systems and commercial server rooms

Fujitsu Wall mounted air conditioning units are often used in Domestic Air Conditioning Systems and commercial server rooms where space is limited or an area is otherwise difficult to keep cooled. The wall mounted air conditioning unit is the easiest to install and the cheapest to buy, resulting in the lowest priced installed air conditioner unit. These wall mounted air conditioning units are attached to the wall above head height and blow hot or cold air into a room from one louver. These Wall Mounted Air Conditioning Systems are operated via keypad remote controls or wall mounted control panels.

All our air conditioning systems have a heat pump option in addition to their standard air conditioning feature. New technologies mean that these units are extremely quiet when running and have improved energy savings.

These units come with one outdoor condensing unit, known as a single split system and thanks to the flexibility of air conditioning systems, you can choose to run a number of units off of a single outdoor unit, which is known as a multi split. An larger version of this is a VRV/VRF air conditioning system which is commonly used in industrial facilities.

Server room portable air conditioning with auto-restart

A server room or continuos use / stand alone applications air conditioning system should either recycle the condensate water or pump it outside.

Look for a quiet operation with high power with exhaust hose and advanced control features such as power restart after power outage. A unit which has no need for continually emptying condensate water bucket (as associated with budget mobile air conditioning) as it recycles the water for a better cooling performance or pumps it out of the building with the hose which is usualy around 100mm to 300mm on larger portable air conditioning. This makes it ideal for use in server rooms or continuos use/stand alone applications. A mono-block air conditioning unit with a category "A" energy product with non-chlorine based refrigerant such as R410a / R407C and a efficient rotary compressor. portable units come with remote control and most 1 years warranty. Exhaust tube size usually 2 meters long and ducting accessories all included with some models. We sell the RCM4000 and the AB7082

  • Advised manufactures for server room air conditioning Mitsubishi, Daikin, Fujitsu, Sanyo

  • Always use auto-restart units for server room air conditioning units as power failures can shut budget air conditioning down. Take a look at the Portable air conditioning unit RCM4000 (14000 Btu / 4.0 kW).

  • If your server room is temporary (ie short term lease on building) or has building restrictions then Portable / Mobile air conditioning maybe your only option.

  • If using portable air conditioning for your server room then make sure it recycles the water for better cooling performance of that it has a integral condensate pump.

  • Use a established business who will not be going out of business for your server room air conditioning installation as the warranty of the air conditioning is with the supplier not the manufacturer.

Server room air conditioning case study:

A existing client was using a old fixed speed units for their server room air conditioning which was in need of re-newel. We advised using a Mitsubishi Heavy Industrial - SRK71ZE-S1 Wall Mounted (7.1kW 24000 Btu) hyper inverter. These wall air conditioning units are hyper efficient with a cat A energy product label and designed for continual use which many server room air conditioning units require. The old fixed speed units used lots of energy because of the start current as associated with big inductive loads with fixed speed air conditioning. The Mitsubishi Heavy Industrial - SRK71ZE-S1 Wall Mounted (7.1kW 24000 Btu) hyper inverter saved money in the long run and as it is so robust will last.

Further information on server room air conditioning:

As all server room operators know, servers and coms give off a lot of heat! and need to be constantly cooled otherwise they could overheat and shut down causing major problems for businesses.

It is advised when purchasing air conditioning units for server rooms to have energy efficient inverter systems. Generally server room air conditioning will run 24 hours / 7 days a week and the inverter will save energy and equipment failure. Generally cooling is only required but in the UK most systems are heat pump type which heat and cool.

Don't be left with your pants down when your server room air conditioning fails.

Fixed speed systems rarely come with a low ambient kit so if the temperature gets to cold outside then the unit will not cool properly which is a common fault in UK cold winters. The cheaper units also have issues with parts so if your unit breaks down the part required may take weeks to source. That's why it is worth buying up to date systems to future proof your server room cooling.
