Existing Pipe Work On Air Conditioning Units

New split air conditioning systems require new pipe work but some manufactures such as Mitsubishi Electric Air Conditioning now guarantee their machines to use existing pipe work. The reason most manufactures do not guarantee their machines is because refrigerant oil can not be mixed between blends of refrigerant. A good example of this is R22 which used mineral oil and R407 and R410A which use synthetic oil.

What happens when refrigerant oil is mixed in air conditioning systems?

If a mineral oil was to be used with R407 or R410A the oil starts to solidify and stick to the side of the pipes and orifices as the refrigerant breaks it down. This can be a problem in long pipe runs where oil can get trapped in the undulations of the pipe work installation. If installing a new R410A air conditioning unit and the existing air conditioning pipe work was used by a R407 air conditioning system then the pipe work theoretically can be used. The oil is the same synthetic variant and if the installer was to blast the pipe through with nitrogen to clear any residue of oil out of the run then there would be no problem.

Saving to be made when reusing air conditioning pipe work

When air conditioning companies are quoting there maybe significant savings in not changing the pipe work especially on long pipe runs. There is a environmental issue in replacing pipe work and if it isn't unnecessary then why do so. If the pipe sizes are the same or larger by one size i.e if the new air conditioning units are 1/4 + 1/2 gauge pipe and the old system is 1/4 + 5/8 gauges then there will not be a problem but more refrigerant may need to be added. Any larger may not be advised. For complete peace of mind use Mitsubishi Electric Air Conditioning.

Condensate Issues On Server Room Air Conditioning

Condensate Issues On Server Room Air Conditioning:

Server room air conditioning will run 24 hours a day seven days a week to cool the ambient air. This means that on certain days of the year the outside temperature is colder than the server room. I.e if a server room has a required temperature of 19DegC and the outside air temperature is -2DegC. This can throw us issues with the system if this is not planned into the initial installation. A common problem is that condensate water which is collected from the server room can freeze up in the condensate pipe in gravity drain systems.
The condensate pipe of choice for drain line is 22mm overflow pipe or braided 10mm/12mm which has no insulation properties and when exposed to freezing weather conditions with already chilled water coming off a indoor evaporator coil can freeze in long runs of the braided hose. This causes the indoor unit to leak as the pipe gets more restricted and as the ice builds up in the pipe. I have seen insulation around condensate pipe to inhibit the effects of the cold weather.
Cold weather plays havoc with server room air conditioning
Drain lines get blocked in server room air conditioning systems

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.
  • 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 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, Sanyo.
  • 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.
We offer a complete service to IT Managers, Building Managers and Server Room / Computer / COMS room managersCall us for a comprehensive quotation on varied air conditioning manufactures to suit any budget on new installations. We have worked with many Blue-chip organisations in helping them develop their server room air conditioning.

Compact Round flow Cassette System by Midea air conditioning

Compact Round flow Cassette System: Midea air conditioning must be the best value system on the UK market

'via Blog this'

The cheapest way to heat and cool your office.

The Midea Super Slim Round Flow Twin Cassette air conditioning system is ideal for a open plan area where the two cassette units are installed together in the area with the intention of better air distribution. The cassettes come with removable lifting panel makes the clean process much easier.  With the 360° flow system, distributing comfort to every corner of the room.  This unit is only 205mm in height, an improvement over the 230mm heights of the conventional model. Standard high-end touch screen wired controller with failure indication provides a user friendly interface. The units are installed as Twin systems: one outdoor unit can connect with two indoor units. Remote On/Off with the reserved ports, a remote switch can be easily connected to realise remote control. The built in PCB can output an alarm signal, which makes setting up an external alarm light or vibration gauge possible making it ideal for critical applications.
