Case Study of Air conditioning Heat-pump installation at Amey Utilities Waterbeach, Cambridge (14/03/14)

Amey Utilities Office Air Conditioning Case Study

Installation of Amey Utilities office air conditioning heat-pumps:

Orion air conditioning & refrigeration ltd complete the installation of a Fujitsu air conditioning heat-pump heating system for the cabin office building in Waterbeach, Cambridgeshire. The cabin building was in need of revamping due to its age and had 5 areas which needed heating and cooling including a data server room. The building had around 200 meters/squared of area that used a electric convector heating system which was as basic and extremely expensive to run.

Project Pictures:

What air conditioning heat-pumps were installed in Amey Utilities offices and server room:

5 x  Fujitsu Air Conditioning AUYF24L Compact Cassette ( 7.0 kW / 24000 Btu) Heat Pump Inverter, 2 x Fujitsu Air Conditioning AUYF12L Compact Cassette ( 3.5 kW / 12000 Btu) Heat Pump Inverter and 1 x Fujitsu Air conditioning ASYG18LF (5Kw / 18000Btu) Wall Heat pump Inverter for the server room. These units have a high COP (Average 3.65 initial input on) which means that every 1000w of electrical energy going in produces 3650 watts of heat. For more information on heat-pump inverters please here.

Background of the Amey Utilities office air conditioning heat-pumps:

The main contractor conducting the refit was P.B Doyles who were quoted on various heating systems including split heat pump systems and replacement electric heaters which came in under budget in comparison to the price of the Fujitsu air conditioning Heat-Pump units but did not offer cooling which the cabin office would need in the summer. The Fujitsu air conditioning heat-pump system provided a great value way of heating a office building within a short space of time (30 mins heat up time) and with little cost and reduces CO2 emissions. The Fujitsu  air conditioning systems offer large capacity heating with excellent COP. The Amey project required individual heating and cooling for each area and split Fujitsu systems offer a affordable way of heating and cooling without the need for centralized air conditioning system.

Office air conditioning VRF Heat-pump efficiency and CO2 emissions:

This office air conditioning heat-pump system took around half an hour to heat fully but once warm the outdoor heat-pump ramped down because the temperature  had been reached therefore just pumping small amounts of heat in to maintain heat. Typical running cost for the year / system £474.50p.

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 managers. Call 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.   Call:             +44(0)845 567 7080        for details on server room air conditioning quotations.

How To Claim Enhanced Capital Allowances On Air Conditioning and Heat Pumps

Buy ECA heat pumps and air conditioning at www.orionairsales.com

Enhanced Capital Allowances (ECAs) are a tax relief given through the tax system by reducing the taxable profits of the business. The ECA scheme builds on existing statutory provisions, under which businesses may obtain tax relief, in the form of capital allowances, for their investment in plant and machinery.

Capital allowances allow the costs of capital assets to be written off against a business's taxable profits. They take the place of depreciation charged in the commercial accounts which is not allowed for tax. The main rate of allowances for plant and machinery is 25% a year on the reducing balance basis, which spreads the benefit over a number of years (about 95% of the cost is relieved in 8 years). ECAs have been granted in other areas before but this is the first time that they have been introduced for use to support energy efficiency. ECAs enable businesses to claim 100% first-year capital allowances on their investment in designated energy-saving plant and machinery in the year in which the expenditure is incurred. ECAs bring forward relief, so that it can be set against profits of a period earlier than would otherwise be the case. The benefit to businesses of ECAs is thus a cash flow boost resulting from the reduction of the business's tax bill of the year in which the investment is made. Capital Allowances can be claimed on capital expenditure incurred on the provision of plant and machinery for use in a business's trade. It is a requirement of the legislation that as a result of incurring the expenditure the machinery or plant belongs to the person making the claim. Some assets will not qualify for ECAs. These include assets that are buildings or structures as defined by sections 21 to 23 Capital Allowances Act 2001 as these assets do not qualify for plant and machinerycapital allowances.

Claims for ECAs are made in the same way as other capital allowances on the Corporation Tax Return for companies and the Income Tax Return for individuals and partnerships. The Inland Revenue's guidance on the ECA scheme can be found at www.inlandrevenue.gov.uk/capital_allowances/eca-guidance.htm.

The Inland Revenue administers claims for ECAs and they have wide-ranging powers to investigate any aspect of the return. If errors are identified, any tax underpaid may be recovered with interest and, in cases of negligent or fraudulent conduct, penalties. Penalties cannot exceed 100% of the tax that would otherwise have gone unpaid.

Claims must be based on the costs incurred. Where you have purchased a qualifying Product that is not already incorporated into a larger item of plant and machinery you must use the price paid for the item as the base of your claim. If you have purchased a qualifying product which is incorporated into a larger piece of equipment, the eligible claim value is provided in the Claim Values section of this site. The remainder of the equipment can attract capital allowances at the normal (rather than the Enhanced) rates.

The words ‘on the provision of machinery or plant’ in the Capital Allowances Act are interpreted narrowly and exclude remote or indirect expenditure. Some common types of cost are detailed below:

Direct transportation and installation costs can be regarded as expenditure on the provision of plant or machinery. These can include, for example, the costs of transport, crainage costs to lift machinery in to place, project management costs, installation, modifications to existing plant and machinery, and commissioning.

Professional fees qualify only if they are directly related to the acquisition and installation of assets that are plant or machinery. Fees incurred on such things as feasibility studies or design work are generally too remote from the acquisition and installation to qualify. The eligibility of such costs is a question of fact based on the particular circumstances of the case.

Costs of alteration to an existing building arising as a direct result of the installation of qualifying plant and machinery may be eligible for ECA.

For information on claiming products under specific technology groups, please see the "Products and Claims" section of the site. http://www.eca.gov.uk
