ebm-papst worked together with Cinque Energy Solutions and Stulz to provide energy saving solutions for Diamond Light Source, one of the UK’s leading scientific organisations.

The fans

Existing air-conditioning equipment was upgraded with ebm-papst EC fans, which dramatically reduced cooling energy consumption.

The project

Stulz asked ebm-papst to carry out a site survey for upgrading some of its computer room air conditioners. Normally used for datacentre cooling, the unit was being used to cool electronic equipment rooms around the perimeter of the Diamond Light Source synchrotron. Phase one of the project was to upgrade 27 CCD900CW Stulz downfl ow CRAC units from their traditional AC forward curved centrifugal blowers to EC backward curved impellers. An initial site survey identified what the current solution delivered in terms of power draw and performance. Suitability for upgrade also had to be considered.

The Solution

The blowers would be replaced by EC backward curved impellers, but due to space limitations resulting from the use of a scoop directing air into the room, the EC solution had to be mounted within the CRAC unit enclosures rather than below. The proposed solution was to utilise the excellent energy efficiency of the latest RadiCal 560mm impeller from ebm-papst. The fans were mounted into bespoke metalwork frames to angle the airflow to assist with the air delivery into the room. Metalwork and assembly was all carried at ebm-papst’s dedicated production area devoted to custom solutions.

Hastings-based New Career Skills Limited charged fees of up to £6,000 to retrain mature career-changers for jobs as plumbers, green engineers and electricians. But now administrators from KPMG have been called in and closed the Southampton training centre that David Cameron visited three years ago to celebrate the firm’s track record for growth and retraining people for second-chance careers in construction. NCS was founded 15 years ago and in 2008 and was named as one…

Major energy suppliers will raise less under the “green levy” as ministers move to cut rising fuel bills for households.

The move will cause outrage among insulation suppliers who have been campaigning hard to keep the levy. The Government said it will be “reducing the cost of the Energy Company Obligation (ECO), an insulation scheme delivered by major energy suppliers.

“This will result in £30-£35 off bills, on average, next year.”

Ministers are hoping to counter industry fury over watering down of the scheme with a package of energy efficiency measures worth £540m over the next three years.

These are:

  • In future, when people buy a new home, they could get up to £1000 from the Government to spend on important energy-saving measures – equivalent to half the stamp duty on the average house – or up to £4000 for particularly expensive measures. The scheme will be available to all people moving house including those who don’t pay stamp duty, helping around 60,000 homes a year.
  • Government will also introduce a scheme to support private landlords in improving the energy efficiency of their properties, which will improve around 15,000 of the least energy efficient rental properties each year for three years. Together, the homebuyers and private rental schemes will be worth £450 million over three years.
  • £90 million over three years will be spent improving the energy efficiency of schools, hospitals and other public sector buildings.

Paul King, Chief Executive of the UK Green Building Council, said: “Make no mistake, this is bad news for people who cannot afford to heat their homes, especially if they live in solid walled properties, and bad news for thousands of construction industry workers who may well be joining the dole queue this Christmas.

“It remains perverse that the Prime Minister is attempting to reduce energy bills by slashing the very scheme that is designed to bring them down for good.”

Does your air conditioning system, chiller or heat pump use R22 refrigerant? If so, it’s time to take action.

R22 has not been legal for use in new air conditioning equipment since 2004, then in 2010, the ODS Regulation imposed a ban in all EU member states against the use of new R22 gas to maintain existing cooling systems. Since then, recycled R22 has been used to maintain and service systems, but this is set to change at the end of 2014. Take a look at the timeline at the bottom of this post for details.

From January 2015, it will be illegal to use HCFCs, which includes the refrigerant R22, in any air conditioning, heat pump or cooling systems in the UK. Studies have shown that these potent greenhouse gases are significantly damaging the ozone layer so the EC Ozone Regulation has imposed a phased ban across the EU member states.

As R22 gas is needed to complete most repairs and services of systems using the refrigerant, maintaining these systems effectively will be almost impossible in a year’s time. If your units rely on R22, you have two options:

1)      Replace your existing system with new equipment

2)      Replace parts on your current system to enable it to work with an alternative refrigerant

Our highly experienced engineers at Cinque Energy Solutions will happily visit your site to survey your equipment and discuss which solution is best for you. They’ll then install your new system for you, or replace the necessary parts to make it compliant with the new legislation.

Thankfully, the full value of your installation can currently be claimed against your corporation tax under the government’s Enhanced Capital Allowance (ECA) scheme, so you don’t need to worry about the cost of a new system.

What’s more, your new equipment could save you up to 40% on your energy costs as advancements in technology mean it’ll be more energy efficient. That’s a whopping financial saving and carbon footprint reduction.

There are still 750,000 units in the UK that need to be upgraded or replaced. Is yours one of them? Get in touch with us today and we’ll make sure your critical business operations continue to run smoothly by helping you adhere to the new legislation.

 

R22 Ban Timeline

1st July 1995 – HCFCs banned except as solvents, refrigerants, for the production of rigid insulating foams and integral skin foams in safety applications, in laboratory uses including research and development, as feedstock in the manufacture of other chemicals and as a carrier gas for sterilisation substances in closed systems.

1st January 1996 – HCFCs banned in equipment produced after 31st December 1995 as refrigerants in non-confined direct evaporation systems, refrigerants in domestic refrigerators and freezers, in motor vehicles, tractors and off road vehicles or trailer air conditioning and inroad public transport air conditioning.

1st January 1998 - HCFC banned in equipment produced after 31st December 1997 for rail public transport air conditioning.

1st January 2000 - HCFC banned in equipment produced after 31st December 1999 for use as refrigerants in public distribution and cold stores and warehouses and as refrigerants for equipment of 150kW and over shaft input.
