My air conditioning is not working. What should I do?

As the outside temperatures rise and the sun is beating through the windows, it is tempting to turn your portable air conditioning down to as low as 16 degrees, thinking that the colder the air conditioner is set, the faster it will cool the room. 
In fact, this is not how the cooling units work.  Whatever the temperature is set at, an air conditioner will pump out the same amount of cool air, and setting it at a lower temperature only tells it when to stop pumping out the cool air, rather than speeding up the cooling effect.
The air conditioning units should ideally be set at around 24/25 degrees, to ensure that the units are not working so hard that they stop working altogether. 
The models most affected by the hot temperatures are the Climatemaster, KY32, Trotec 2600, PKY12 or Compact 12, whereas units such as the Weltems, can cope with the exceptional temperatures.
If your portable air conditioner does stop working or is not cooling the room, there are a few things you can do –

When is hot too hot in the Workplace?

Employers have a legal obligation to provide a ‘reasonable’ working temperature which is covered by the Workplace(Health, Safety and Welfare) Regulations 1992.  Safe working temperatures are important in any work environment. 

Excess heat can cause drowsiness which could lead to mistakes or unfinished work.High temperatures can also cause heat stress and other health problems.Heat stress occurs when the body’s means of controlling its internal temperature starts to fail. As well as air temperature, factors such as work rate, humidity and clothing worn while working may lead to heat stress.
Maximum Temperatures
Surprisingly there is no legal maximum safe working temperature - the only requirement is that workplace temperatures in buildings should be ‘reasonable’. (Workplace Regulations 1992).A meaningful maximum figure cannot be given due to the high temperatures found in, for example, bakeries, glass works or foundries. In such environments it is still possible to work safely provided a…

London Cool ensures compliance with EU F Gas Regulations

Companies who service air conditioning units containing F Gas (fluorinated greenhouse gas) must, under a 2014 EU regulation, be certified to handle the F Gases.

London Cool is registered with REFCOM (Register of Companies Competent to Manage Refrigerants), to show that we are certified to service stationary air conditioning and heat pump systems containing F Gas.Servicing includes installing, repairing, maintaining, leak testing, commissioning and decommissioning.Our engineers also have to be qualified as individuals if they handle F Gas.
REFCOM has been appointed by the Secretary of State for Environment, Food and Rural Affairs (DEFRA) to operate as a certification body under the EU fluorinated greenhouse gas (F gas) regulation.
In addition, all our air conditioning units containing F Gas must be labelled as part of the written procedures for handling F Gases and the equipment used.We have developed a comprehensive set of labels to ensure we are fully compliant with these requirements …

F Gas Regulations and your air conditioning system

The use of fluorinated greenhouse gases (F gases) like hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6) is governed by Regulation (EU) No 517/2014 and impacts anyone who -
·manufactures, uses or services equipment that contains F gases, like refrigeration and air conditioning systems, solvents or aerosols ·produces or wholesales F gas ·imports or exports F gas, or equipment containing F gas, to or from the EU
Many air conditioning and heat pump systems contain F gases.Companies that operate or service and maintain fixed air conditioning units containing F gas must meet the following requirements. Check if your cooling system contains F gasLook at the list of Fgases regulated by the EU.HFC 404A and HFC 410A are common in air conditioning and heat pump systems.To find out if your equipment contains one of these F gases you can: ·check your manual or the labels on your equipment ·if we installed your equipment, then contact us for advice

How air conditioning can help relieve the misery of hay fever

With the advent of summer, while we all appreciate the warmer weather, pollen-laden flowers, trees, grasses and weeds, can bring on the misery of hay fever for many people.  

Hay fever is an allergic reaction which many people are susceptible to, particularly between 5am and 10am, when the pollen count is at its highest.

According to NHS Inform, on humid and windy days, pollen spreads easily while rainy days will help clear pollen from the air, causing pollen levels to fall.  During their pollen season, plants release pollen early in the morning. As the day gets warmer and more flowers open, pollen levels rise. On sunny days, the pollen count is highest in the early evening.
There are tablets and medicines on the market to help relieve the symptoms, but there are other simple things that can be done to makedaily life a bit more comfortable.
Using your air conditioning system effectively can help to manage hay fever symptoms as the installed air conditioning unit cleans the air within your…

Evaporative cooling systems and Legionnaires' Disease

One of the questions we frequently get asked is whether you can catch Legionnaires’ disease from evaporative coolers. 
We are happy to report that there have been no recorded cases of a portable evaporative cooler causing Legionnaires’ disease and research indicates transmission of the bacteria is not possible by the evaporative method. What is Legionnaires’ disease? It is a very serious type of pneumonia caused by breathing in small droplets of water that contain bacteria called Legionella. Legionella bacteria are found naturally in moist environments such as lakes and rivers, and other water sources. The bacteria causing Legionnaires disease are very common, but only build up to dangerous concentrations in - ·Warm, stagnant water - evaporative cooling fans operate from a supply of cold fresh water, so the bacterium doesn’t have the opportunity to multiply. ·Limescale and slime – regular cleaning of wet surfaces with a mild bleach solution, will prevent a build up forming.

London Cool keeps Cask 2018 cool

Recently we visited a micro-brewery, Affinity Brew Company, in Bermondsey, London SE16, to carry out an on-site demonstration of some portable cooling equipment.  The reason they needed some portable cooling is that over the weekend of 7 and 8 April they were holding a beer festival – Cask 2018 – and were looking for an efficient way of keeping the cask-conditioned beers cool so they could be enjoyed at their best. The kegs were to be stored in insulated racks either 2m x 2m or 4m x 2m x 0.5m which would be kept cool with an air supply at 8 degrees.  London Cool delivered two Weltem spot coolers to the brewery to deliver cool air to each rack.
Affinity Brew Company partnered with another micro-brewery – Partizan Brewing - who are located just around the corner on Raymouth Road – to put on this event.Billed as ‘a cask beer festival the like of which we don’t think you’ll have seen before’ it showcased some of the UK’s ‘finest and most exciting breweries’with 30 different cask beers on t…
