With a wealth of industry experience, our engineers possess the know-how and technical expertise to ensure each and every installation is executed to the very highest standard.
Always polite and professional, our engineers combine their skill and vast experience with a dash of common sense to deliver great air conditioning installation results time after time.
We consider ourselves to be a customer-focussed air conditioning solutions provider and we strive to be the one-stop-shop for all your air conditioning installation, servicing, repairs and maintenance requirements.
Our sole objective is to deliver the best service we can before, during and after each contract, so our approach is very much hands-on with open communication at all times.
Providing air conditioning solutions to a wide customer base, we’re familiar in dealing with residential clients, small local businesses, retailers, public sector organisations such as schools, colleges and leisure centres, through to nationally recognised banks, commercial and industrial organisations.
You can be sure we will only propose a system if it delivers the right solution for you.
Taking out a Scheduled Servicing agreement on your air conditioning equipment will help prevent unnecessary, potentially expensive breakdowns while reducing the risk of lost downtime. Our Scheduled Servicing agreement gives you immediate priority over non-contract clients.
Scheduled Servicing will improve the efficiency of your air conditioning equipment so you can save a significant amount on running costs during its lifetime. Scheduled Servicing will enhance the lifespan of your air conditioning equipment while importantly enabling you to maintain the manufacturers initial warranty.
What size air conditioning unit will I require?
In order to provide a successful cooling solution you need to understand the power and heat requirements being generated/consumed as well as the environmental factors that are at work. Calculating the size of the air conditioning unit for your server room, data centre or secure equipment area (even if it's just a small cupboard/room) is based on a number of factors and this quick guide attempts to deal with some of the issues involved.
In principle it's relatively easy to calculate the size of air conditioning units you need for you server/telecoms room, just add together all the sources of heat output (including any air conditioning equipment) and install an air conditioning unit that has the capacity to remove equal amounts of heat (allow for equipment additions and changes and any future expansion plans).
What size air conditioning unit?
In practice it's more complicated especially for larger data centre, server farms and medium to large organisations where specific equipment may require specialist solutions to deal with hotspots.
In some premises fire regulations often require server rooms to have levels of insulation far above that of a normal office and in these circumstances additional requirements have to be met. Computer rooms tend to run 24hr X 7 days a week, providing sufficient cooling is essential to ensure reliable running of servers, switches, routers, communications, ups equipment and air flow rack cabinets. Whilst technology has and continues to reduced the size of equipment and in some cases the amount of heat generated by processors and disks the requirements for optimum operating temperatures for this type of equipment has become more stringent (and will continue to be so) if you are to limit downtime and system failure.
The Technical detail:-
The amount of heat generated is known as the heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.
The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat that can be calculated*.
Factors include:
The floor area of the room
The size and position of windows, and whether they have blinds or shades (if any)
The number of room occupants (if any)
The heat generated by equipment
The heat generated by lighting
The amount of cooling required depends on the area of the room. To calculate the area in square metres:
Room Area BTU = Length (m) x Width (m) x 337
If, as is quite common, your Server Room has no windows, you can ignore this part of the calculation. If, however there are windows you need to take the size and orientation into account.
South Window BTU = South Facing window Length (m) x Width (m) x 870
North Window BTU = North Facing windows Length (m) x Width (m) x 165
If there are no blinds on the windows multiply the result(s) by 1.5.
IF you are in the Southern Hemisphere you would swap the conversion factors as the heat on North facing windows is then greatest.
Add together all the BTUs for the windows.
Windows BTU = South Window(s) BTU + North Window(s) BTU
Purpose built Server Rooms don’t normally have people working in them, but if people do regularly work in your Server Room you will have to take that into account. The heat output is around 400 BTU per person.
Total Occupant BTU = Number of occupants x 400
Clearly most heat in a Server Room is generated by the equipment. This is trickier to calculate that you might think. The wattage on equipment is the maximum power consumption rating, the actual power consumed may be less. However it is probably safer to over estimate the wattage than underestimate it.
Add together all the wattages for Servers, Switches, Routers etc and multiply by 3.5.
Equipment BTU = Total wattage for all equipment x 3.5
Take the total wattage of the lighting and multiply by 4.25.
Lighting BTU = Total wattage for all lighting x 4.25
Add all the BTUs together.
Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU
This is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.
