A new type of refrigerators could, in the coming years, replace the classic ones. Those new fridges that are far cheaper, quieter and more efficient work using a process called magnetic refrigeration. This technology has been known and experimented with for a long time but it can now be applied to domestic appliances and could even be used in various applications. Continue reading →
There are many different aspects to take into account when buying a commercial refrigerator. They come in different shapes, dimensions and functions which makes it hard to select the correct one for your business.So here is a little guide to help you choose your commercial refrigerator.
In a commercial environment it is important for all equipment to be maintained appropriately as the cost of repairs and the effect a non-functioning piece of equipment can have on a business can be huge. If your refrigerator is properly maintained this will increase efficiency, reduce running costs and longevity of the unit.
It is important that you carry out some maintenance on your refrigeration unit, not only to keep it running but to ensure you are adhering to the Environmental Health Organisation’s regulations.
Here at G T Refrigeration we have put together some quick tips for you to ensure your units are kept up to a high standard.
It is important that you check your door seals regularly. This is because if they are split, cracked or not fitted correctly, this is the perfect breeding ground bacteria and it will also lead to loss of energy which isn’t efficient. Continue reading →
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.

Before refrigerators as we know them were invented they used to be a box that was topped up with ice regularly in order to keep food cool. At the beginning of the 20th century Frigidare launched their first electronic fridge for households. They had sold 200,000 models by 1926 and had to build a new factory in order for them to keep up with demand!
The bare bones of what a refrigerator does is push hot air outside the unit in order to keep the contents cool. The most common way of doing this is by tubes that are filled which a chemical liquid (refrigerant) which boils when the air pressure is reduced. Once it has boiled it turns into a vapour which then absorbs energy. This is the process that transfers energy from the inside of the fridge to the outside, therefore keeping the contents cold.

Costco have been hit with a $335,000 fine and they will need to pay $2 million in remedial measures because they have not recorded R22 leaks over the last 3 years.
Costco are the second largest retailer in the US and they had previously promised to cut their emissions from refrigeration and they were planning on doing so by improving their units in more than half of their stores across the country. Continue reading →
Every so often, something weird and wonderful comes from the air conditioning and refrigeration world, hence the air conditioned suit. This week we have heard that now refrigerator magnets may be able to cool fridges!
Everyone loves a fridge magnet and it is predicted that in the future they will be so much more than clutter for the front of your fridge. According to MIT researchers they could be used as the cooling agent.
Their theory explains that the magnons that are found in magnets rotate and is called “spins” as well as these spins, the magnons also give off heat and according to the research that was carried out that when the magnons are introduced to a magnetic field, they travel from one end to another. This means that the heat is taken with them and therefore a cooling effect occurs. Continue reading →
There has been a lot of talk during the year about F Gas rules and now it has been confirmed that the regulations will be here in January, it is important to understand all the details so not to be caught out. This will ensure that you aren’t taken by surprise and you can take steps to plan accordingly.
Ray Gluckman is the technical director at Enviros and he has worked with those making the policies surrounding F Gases. He has suggested that the timing of this particular phase down will give companies a false impression to what is going to happen in January. Continue reading →
When you walk into a supermarket it is no surprise that the fridges, and sometimes the freezers, don’t have doors on them, yet at home you wouldn’t even dream of having the fridge door open constantly. Well this subject has been up for debate for the last three to four years because not only will having doors on refrigeration units reduce the supermarkets energy, it uses less energy and therefore they operate at a more environmentally friendly level.
There are many benefits to putting doors on refrigeration units including lowering the electricity bill, LED lighting can be used and enhance the look of the products and the aisles won’t be unnecessarily cold, providing a better experience for the customer too. Continue reading →
Although we are only just at the end of February, if the last couple of years are anything to go by the warmer weather is very nearly here! This means it is time to start that vital preparation work on your air conditioning systems.
Franks Landwehr is the vice president at Emerson Climate Technologies and he has said “Learning what maintenance steps you can take on your own and what questions to ask your air conditioning contractor can save you time, money and keep you comfortable this season.” Emerson Climate Technologies are a huge provider of HVAC and Refrigeration systems.
Of course there are some things that need to be outsourced and dealt with by a professional but there are some things you can do to extend the life of your air conditioning systems. Changing air filters is essential and it is recommended that the indoor ductwork filters are changed every three months. If you are doing this yourself make sure you have the correct fitting filters so they fit properly. Make sure there is a reliable air flow so the amount of moisture is reduced which could potentially lead to mould. The duct grills need to be cleaned once a year to clear and debris or dust. You don’t want this circulating as well as cool air!
It is inevitable that at some point you will need to replace your system with a new one, how soon after purchase depends on how well it is looked after. Landwehr suggested a few tips when it comes to buying a new system. One of these was to make sure you know what you are talking about when buying a new air conditioning unit. This will mean you will have a better idea of what you are being sold and it could end up saving you money.
