DEDICATED TO KEEPING YOU COOL

The F-gas Regulation which aims to contain, prevent and thereby reduce emissions of HFC/PFC based refrigerants. The F-gas Regulation states that any systems that have over 3KG of refrigerant, must have an annual leak detection test. This Regualtion is effective as of the 4^th of July 2007.

Multi service chilled beams have been selected by Heathrow’s Terminal 5 to provide the best possible levels of comfort cooling for passengers and staff in the main arrivals corridors.

Active and passive Trox beams are also being integrated into the ceilings in other critical areas.

Water cooling systems and evaporative condensers can be essential requirements in a commercial or industrial application, yet they have received notoriety because of outbreaks of Legionnaires disease.

There are three typical methods that can be used to cool buildings: ventilation (free cooling); evaporative cooling or refrigerant-based air-conditioning systems. The choice of the system can have a dramatic effect on the total carbon emissions of the building due to their electrical demands.

Ventilation systems

Ventilation systems can provide free cooling for most of the year, but during the hot summer months of high temperature the system is unable to maintain internal temperatures below 25°C.

The energy performance of building directive states, that an air-conditioned system that has a collective cooling capacity larger than 12kw must be inspected regularly by an accredited energy assessor.
 
The person who has control of the operation of the air-conditioning system has to ensure that the system is inspected at regular intervals not exceeding 5 years.

End-users, such as supermarkets and large businesses have now realised the importance of publicising their green credentials, with corporate responsibility becoming a competitive issue.

In response to this, the industry are working to improve the efficiency of traditional systems as well as a move to alternative solutions such as heat pump systems. These developments mean that solar power has now emerged as a variable way of powering, or partially powering, an air conditioning system.

The European Union's F-gas Regulation No 842/2006 became law on 4 July 2006. This imposes obligations on "operators" of this equipment from 4 July 2007. F-gases include HFCs are the most Common refrigerants in air conditioning systems today. The Regulation aims to minimise emissions and escape of these gases, which affects global warming.

It’s been said that one possible conclusion to the new Part L regulations is that chilled beams could take over from fan coils as the most popular ventilation system. Whether or not this proves to be the case, professionals take a closer look at this extremely versatile form of ventilation.

In 2007 the Government has set new targets and regulations for energy use in new and existing dwellings. At the end of 2006 Chancellor Gordon Brown set out his vision for green homes in his budget report. His goal is that all new homes should be a ‘zero carbon’ by 2016. As an added incentive the Chancellor removed stamp duty on zero carbon homes, starting 2007.

Homes In the UK are responsible for producing around 25% of the country’s carbon emissions, though heating, lighting and use of appliances.

Ahead of a Europe-wide ban on the use of disposable cylinders for topping up air- conditioning systems, refrigerant supplier BOC is urging maintenance companies to change the cylinders these use.
