New legislation: Are you equipped with an air conditioning system working with R22?

gtr-blogEarlier this year, a new legislation was enforced banning the use of Hydrochlorofluorocarbons including R22 gas. R22 is a gas used in AC systems that weaken the ozone layer and many AC units pre-dating 2004 use it. HCFC, which are petroleum-based products, have been replacing the CFCs (Chlorofluorocarbures) since 1995. Until recently they were considered acceptable interim substitutes for CFCs. However, even though far less polluting than CFCs, HCFC’s are still harmful to the environment. R22 has been extensively used in many systems before 2004 but as of the 1st January 2015, the use of any appliances that might contain this fluid is no longer permitted. Continue reading

F Gas Legislation


With new F Gas changes coming in January 2017 Defra consultation has said in a report that nearly half a million new air conditioning units will have to have a different process put in place when it comes to checking for refrigerant leaks.

They have written an Impact Statement after a public consultation was carried out which states “the new EU Regulation is expected to lead to an extra 350,000 small systems requiring mandatory leak checking, 15,000 large systems requiring automatic leak detection and 60,000 refrigerated trucks and trailers being included in the leak checking regime.”

The amount of new units that need will need servicing means that there will be more work for engineers and contractors not just for air conditioning units but for refrigeration too. There are some smaller systems too that will need to be maintained but these are usually done by the end user. However, with the new system in place they will have to be retrained so they are making the correct checks. Continue reading

Cooling your home without using electricity?

American Flag

Air conditioning is one of those things that gets fought over in the office during the summer as there are always those that are too cold or too hot. It is now winter and hopefully the fights have cooled down along with the temperature (pardon the pun), however this doesn’t mean that you can forget about your system. With this in mind and the importance climate change coming to the forefront of conversations a team of researchers have revealed that they have found a way to cool a room without increasing demands in time for next summer.

The team that have come up with this new system have said that in the USA alone, 15 per cent of the energy used in buildings is spent running air conditioning systems. As it is likely that air conditioning systems are only run during the summer months this seems like a reasonable percentage however, there is a huge amount of electricity generated from coal based power plants which in turn creates a lot of carbon emissions.

India not likely to sign up to HFC Phasedown anytime soon

Indian Flag

Last week there were global climate talks in Paris and the outcome was that India are leading the way in terms of refusing to sign up to the proposed HFC phase-down. However, they didn’t just refuse, they of course had reasons to justify their decisions. Prakash Javadeker is the environmental minister and voiced the reasoning behind their decision to refuse the proposal. Continue reading

Understanding HVAC Legislation

The World

As a business it is essential that you understand UK air conditioning and refrigeration laws. The regulations state that: “If you own or operate equipment that contains ODS or F-gases, such as air-conditioning or refrigeration, you will need to manage your own equipment to prevent polluting the environment.”

In order to do this you must ensure that you recover, contain and destroy the refrigerant gasses in an appropriate manner. You must also ensure that checks are carried out on your air conditioning unit at least once a year for leaks in small units but if you are using a larger system then this needs to happen on a more regular basis. You can either do this yourself or get a professional to do it. The latter is the advised option so you are sure it was completed by a professional and mistakes are less likely to have been made. You mustn’t handle the refrigerants yourself, if this is required call a qualified technician to carry out the task for you. It is also important that you make sure you are aware of any imminent changes that will be occurring to the legislation so you can stay on top of it and up to date. Continue reading

Marks and Spencer’s Refrigeration Policy

Contents of a Fridge

Most will rememberthe sixties for the fashion and music, but something else happened during this decade that us HVAC’ers will be far more interested in! This decade saw a rise of the refrigerator in households.

In general, the basics of refrigeration have remained mostly the same although a lot has changed. The refrigerator is now an important staple to any commercial or domestic kitchen which ensures food waste is reduced by extending the life of produce.

However, as you and everyone else is well aware of, it has been discovered that the refrigerants used in the refrigerators is not the most environmentally friendly. Paul Alway is the refrigeration specification manager at Marks and Spencer and he explained: “Over the years, society came to understand the atmospheric (ozone layer) impacts of refrigerant gases such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) and the threat they pose on the ozone layer.

The Sistine Chapel Received a new Air Conditioning System

Sistine Chapel

The Sistine Chapel is world famous and as it has grown in popularity in terms of visitors the air conditioning and lighting systems have had to be upgraded to ensure the frescos are preserved.

Currently the amount of people that visit each year pose a threat to the precious paintings so it was vital the temperature was kept at a constant so more visitors can enjoy the paintings for years to come.

Work was carried out on a brand new heating, ventilation and air conditioning system for the Chapel to ensure that the works of art created by Michelangelo did not deteriorate. The Vatican Museums have said that the new system was installed by Carrier who are an American air conditioning company and they have installed a system that had minimum noise and would limit the amount of air movement around the paintings.
