Saga Healthcare Server Room Air Conditioning and Humidity control

Server Room Air Conditioning and Humidity control at Saga Healthcare:

Orion air conditioning has completed the installation of a replacement server room air conditioning system for Saga Healthcare in Hatfield. The existing mix of cassette and wall mounted air conditioning units were R22 which is now banned for use in the UK and R407c which is banned for use in the UK from 2015. Because the units were old and fixed speed (either on or off according to the thermostat) the efficiency had dropped and the technology had become outmoded. The systems were at the end of their economical and safe life span.

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.

What air conditioning units were installed at Saga Healthcare:

4 x  Mitsubishi Electric Air Conditioning Power Inverter Mr Slim PKA-RP100KAL (10kW / 33000 Btu) which provided enough cooling for the 15 meter square area and 6  server racks in the server room with spare cooling capacity in case of failures. The full replacement of the existing systems with all wall air conditioning units, instead of a mix of cassettes was a safer option because when air conditioning unit fails they tend to leak water. If the water leaks out of a cassette it can drip into the top of important server equipment, with wall 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 of air conditioning. 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. 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: 20000 Watts

Total heat loss: 2550 Watts@85%

Room in Square Meters: 18750 Watts

Total Heat Load: 21300 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.

The Daikin Air Conditioning Ururu Sarara Humidification Unit Ideal air conditioning for growing plants indoors

When growing plants indoors under lights such as HPS or MH bulbs the heat produced from the bulbs can cause the plants to dry out and cause problems. Heat is a major problem in the indoor garden and sometimes fresh air in and extract never is enough to bring the heat down forcing the gardener to get a air conditioning unit to cope with the heat. The major downfall with standard air conditioning is that it dehumidifies the air drying out the plants and causing humidity issues in the indoor garden. The standard for many indoor gardens is the portable air conditioning unit which has a flexible tube coming out of the back which is extracted to the outside and a bucket to collect the moister taken out of the indoor garden. These are basic air conditioning units for cooling but have drawbacks including being noisy and issues with the extract tube.

The Daikin Ururu Sarara Humidification Heat-pump inverter wall mounted split air conditioning unit is the new system that could revolutionise indoor garden cooling and winter heating humidity issues. The Ururu humidification evenly heats and cools the entire room and incorporates both an air conditioner and a humidifier, making ideal heating / cooling possible. The URURU humidification subsystem effectively supplies the 450ml/h of water required to fully humidify an entire large grow room. Unlike a standard humidifier, this indoor unit has no water tank. Thus no need for a water supply and no time-consuming cleaning. This feature also eliminates the worrisome growth of bacteria and other micro-organisms which will also kill passagens that may cause problems in the garden.

All the moisture in the outdoor air available inside with the Ururu humidification as the subsystem uses a special built-in humidification element in the outdoor unit to absorb the moisture present in the outdoor air and send it to the indoor unit. Since moisture is not absorbed from the room’s air, quick and effective humidification is possible even with the drier air of winter.

Humidified air feels warmer, dry air actually makes your room feel cooler. Ururu humidification at moderate levels and a relatively low temperature will probably leave your indoor garden cooler.

URURU humidification: maintains a comfortable humidity level without any separate water supply. With only 209mm height this unit fits into smaller spaces than conventional wall mounted units. SARARA dehumidification: maintains a comfortable and fresh indoor environment by removing moisture from the air without lowering the temperature. Whisper quiet operation: down to 23dBA sound pressure level. Indoor unit silent operation: "silent" button on the remote control lowers the operation sound of the indoor unit by 3dBA.

Air conditioning installation for television production ‘I’m A Celebrity Get Me Out Of Here!’ in Costa Rica, Central America

Case Study of Air conditioning installation for television production in Costa Rica, Central America (19/05/09).

Orion Air Conditioning & Refrigeration Ltd has completed a TV production air conditioning project for Elstree Lighting, Power and Rigging in Costa Rica, Central America. The installation was for the production, AV, Satellite uplink and control areas of the television program “ I’m a Celebrity Get Me Out of Here!’ which is a Granada USA Television production.
In total 16 x Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) were installed on the Asur hotel site which held the television production and which is situated within 2km from the base camp from where the production was being filmed. The rain forest conditions threw up some very challenging installation situations including high humidity which was near 90%. Great care was required when commissioning the air conditioning units due to the humidity and on average the units were vacuumed with heavy duty MASTERCOOL ROTARY VANE DEEP VACUUM PUMP 6.3 CFM for around 2 hours to avoid contamination. The humidity was particularly hard on the Condensate Pumps which were extracting 30 litres of moisture every hour in some areas and needed upgrading to the Aspen Maxi-Orange condensate pump which were more powerful and durable to cope with rain forest conditions.

Production Cabins:

In the production cabins 2 x Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) were installed to cope with a 30m squared area which had ambient temperatures of around 36 DegC and excessive humidity. When the units were finally commissioned the area was reduced in temperature to around 23 degC which was the set point. The Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) were pulling out 10 litres / hour of condensate which in the UK is unheard of!

AV Server Area:

The AV air conditioning server areas had up to 20 individual server racks which were all integral to the television production and needed to be specifically cooled to maintain correct operation. The AV air conditioning area had in total 10 individual Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) which were very effective in cooling this TV production area from a start temperature of 37 DegC. The area was required to run at 21 DegC and once the Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) had reached temperature they cycled on one or two of the units which kept the area adequately cooled. The condensate in this area was not such a problem as the units took moisture out of a sealed area.

Satellite Up-link Area:

This area had 2 x Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) systems which covered a area of around 15m square and had various equipment to deal with the live satellite up-link of the production ‘I’m a Celebrity Get Me Out of Here!’ . This was beamed live to the Granada USA Television American offices for live television viewing around the world. The Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) were able to bring this production area down to 19 DegC.

Project Overview:

This project took 7 days to complete and the Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) units performed without a hitch. The high ambient temperatures were not a problem for the Mitsubishi Electric Air Conditioning for the production which is designed to run in 46 DegC. The systems are to be taken out of the production had finished for use on another TV production air conditioning project. The Mitsubishi Electric PSA-RP125GA Floor Inverter Air Conditioning (14 kW / 48000 Btu) were chosen for their powerful output and durability and so far have proven to be just that.
