London Cool have drafted up a long read below regarding the introduction of one of the latest refrigerant gas for installed wall mount, ceiling mount cassette and floor type air conditioning systems.  Manufacturers include Mitsubishi Daikin Fujitsu Daikin and Panasonic Hope you enjoy the read and we will publish soon about new gasses used in portable air conditioning systems also. https://www.londoncool.com/ In 1999 the Kyoto Protocol on global warming listed HFC refrigerants that were contributing to the global warming. This, in turn, led to the introduction of F-Gas regulations in Europe and at the start of January 2015 the next stage of F-gas laws was introduced which detailed the phase down of HFC refrigerant. It is important to note though that this is a phase down and NOT a phase out – with regulations now based on the tonnes of CO2 equivalent of all refrigerants sold or traded in Europe. The air conditioning market moved over to R410a refrigerant in 2006 as it offer...

To protect business-critical equipment from data storage problems or system crashes, it is essential to ensure that the temperature in server rooms or data centres stays within certain limits. With many housing large amounts of equipment, the heat generated can potentially cause computers and networking equipment to fail as they are designed to work within a fairly narrow temperature range.     What temperature is right? Air conditioning should be considered crucial for any server room.   Technology experts recommend a server room temperature of between 18ºC to 27ºC and not less than 10°C or above 28°C.   Relative humidity should be between 45-50% to stop damaging static electricity building up.   Even a few degrees too hot can blow a server chip or cause permanent damage to hard drives.   The cost of a serious server failure can be considerable – not only the cost of replacement, but lost online business, lost customer details, wasted staff t...

With many schools and colleges holding exams and formal assessments, it may be useful to consider the temperature of the exam room to give pupils the best chance of success. Research suggests that temperature influences student attention span, with students in colder or warmer rooms testing poorly compared to those in a control room with a temperature of around 21 degrees. A study at Cornell University found similar results and research is continuing to explain why climate might play such a significant role.   It is thought that apart from the discomfort, which affects memory and learning capabilities, the mind becomes focused on maintaining its body temperature in a room that’s too cold or too hot which then affects concentration.   While warm rooms can make students feel tired and sleepy, colder rooms may make the body use its energy to keep warm instead. Not only would an uncomfortable temperature affect students’ performance, but in extreme cases a sch...

Many people think that air conditioning is just for the summer months, but a number of systems feature a reverse cycle system, or heat pump.  This facility offers extra versatility as the system can be switched between cooling and heating mode as required, keeping the workplace at a comfortable temperature all year round.  Maintaining a comfortable workplace temperature has been shown to improve staff health, safety and productivity. How do heat pumps work? Reverse cycle air conditioning works by warm air passing over a refrigerant to cool it down and lower the temperature of a room during the warmer months of the year. For winter heating, the refrigerant absorbs heat from the outside (even on cold days) to warm up the air going into the room to raise the internal temperature. As well as heating, these systems can also dehumidify the air and are an ideal way to remove airborne fungus and mites from the workplace, creating a more hygienic environment and decreasing t...

Here at London Cool we are finding micathermic space heaters are becoming increasingly popular with our customers.  These heaters are unique in that they combine two methods of heating – convection and radiant heating - to provide fast, efficient and safe heating for the workplace.   When a micathermic heater is switched on, an electrical resistor converts electricity into heat.  As it’s generated, the heat is absorbed by a series of metal coils encased in a silicate mineral – mica - which can withstand very high temperatures.  Mica has high thermal conductivity, ie it’s good at transferring heat, and a high watt density which means it emits energy from its surface when it’s heated up.  Once it is up to temperature, a micathermic space heater generates electromagnetic rays.   The heat is not directly transferred to objects in the room, but transferred to objects via these rays, warming the ambient air as well, and heating up the entire room ...

For many UK businesses the cost of running air conditioning may seem high, but there can be hidden costs of not providing air conditioning or adequate heating in the workplace.   The Workplace (Health, Safety and Welfare) Regulations 1992 state that ‘During working hours, the temperature in all workplaces inside buildings shall be reasonable.’    London Cool also receives many enquiries from businesses needing to keep their server or computer rooms   cool to protect valuable data and systems. Thermal discomfort caused by workplace temperature on can have an impact on health and safety, with more accidents being reported, all of which have an associated cost.   Many employees are not able to adapt their clothing because   they wear a specific uniform or PPE .   Wearing too much clothing or PPE may be a primary cause of heat stress but if clothing does not provide enough insulation, then there is a risk of cold injuries such as frostbite or hy...

London Cool has been very busy supplying portable cooling units for a number of events taking place in London.   Here are just a few - We supplied portable evaporative coolers for event cooling at   The Tabernacle , Notting Hill, London W11, where a programme of events is taking place as part of Notting Hill Carnival this Bank Holiday weekend. The First Dates restaurant is also being kept cool by some of our portable Climateeasy 14 air conditioners plus a Blizzard portable spot cooler.   Not only are the ‘first daters’ likely to get rather warm, but the filming itself generates a lot of heat from all the equipment and lights.   Also, we mustn’t forget that the presence of Fred Sirieix and his staff is also likely to raise the temperature a few degrees! At the famous Somerset House off the Strand in London WC2 we supplied some large warehouse drum fans for events at Somerset House Studios .   Boiler Room TV were presenting the last in their seri...

The British heatwave could well be over and we will see a return to ‘normal’ summer temperatures.   As the temperatures drop, it might be thought that there is no longer a need for portable air conditioning , but on bright sunny days the inside of buildings will still heat up due to solar heat gain, especially in the city centres.   Although the sunlight may not be as strong, the lower angle of the sun means that it is shining into buildings for longer periods during daylight hours.   Buildings that have fully-glazed facades are particularly prone to over-heating caused by solar gain.     C ities with a number of high rise, glass fronted buildings, such as London and Birmingham, are often 1–3°C warmer than rural locations.   To counter this effect, some buildings have solar control glass installed which reflects heat and reduces glare from the sun’s rays.   As well as being practical, it’s also a requirement under Approved Documents L1A and L2S ,...

When deciding whether to buy or hire a portable air conditioning unit, you may come across the term ‘BTU’ or alternatively Kilowatts.     BTU stands for British Thermal Unit and in the world of HVAC  is the amount of heat that an air conditioner can remove from a room.  If an air conditioner’s capacity is measure in Kilowatts then one Kilowatt is equivalent to 3,412 BTUs.  For the science-minded among us, One BTU is the amount of energy needed to raise 1 pound of water 1°F at sea level. Why are BTUs or Kilowatts important when choosing an air conditioner?   Having the correct number of BTUs for the space you need to cool means that the room will be cooled efficiently.   It should also be borne in mind that as the BTU rating increases so does the weight, size and cost of the air conditioner. Too high a BTU means that although the room will cool quickly, the unit will cycle   on and off once the temperature is   reached ...

The first air conditioning systems were in use as early as 1902, but they were not for the comfort of people! According to Tim Hartford of the BBC World Service [1] , Sackett & Wilhelms Lithographing and Printing Company in New York found that varying humidity levels affected the quality of their printing.   The paper had to be printed up to four times in four colours and changing humidity made the paper expand or contract slightly, misaligning the print.   The company approached a heating company, Buffalo Forge, to devise a system to control the humidity.   Engineer Wills Carrier invented the first modern type of air conditioning in which air circulated over coils chilled by compressed ammonia which kept the humidity at a constant 55%. Carrier’s invention soon proved popular in industries where excessive humidity was a problem – such as flour mills and the Gillette Corporation, where excessive moisture would cause the razor blades to rust. The benefi...
