The Japanese firm Fujitsu has presented its new range of air conditioners and splits for this year 2018. Some air conditioning systems that include a presence control system called “Human Sensor” that is responsible for detecting when there are users in the room to regulate the temperature automatically and thus adapt to the needs of each person. » Read more
Ducting for ventilation, heating, air conditioning and dust extraction systems is used to guide and contain the airflow. There are two principal types – solid metal ducts and flexible ducts – but what are the relative merits of each and which should you use?
Metal ducts are usually made from either aluminium or galvanized steel. They last longer than other types if properly maintained, but metal ducting it is more complex to install. It will therefore usually need to be designed by heating and ventilation experts, taking into account all of the aspects of the ventilation or heating system such as the position and type of dust extraction, heating and air conditioning plants.
Metal ducts also tend to take up more space, so the room available in the building and its overall design will be key too. All of this tends to make metal ducting a more expensive option, but its more robust nature may pay off in lower maintenance costs over the long term.
Flexible ducting can be made of a variety of materials, including rubber, stainless steel, polyurethane, and polyester fabric. It can be used on its own or in conjunction with rigid metal ducting.
The choice of material used will depend partly on the nature of the building and on the use to which the ducting is being put. For example, insulated flexible duct from suppliers such as https://www.dustspares.co.uk/flexible-ducting/insulated-flexible-duct.html can be used in warm air distribution systems. Some materials offer better erosion resistance, making them more suitable for applications like dust extraction.
Flexible ducting is easier to install and doesn’t need as much planning as a rigid metal solution. It can also be used to act as a flue in gas installations. It still needs to be properly installed, however, and properly maintained.
When installing it’s important to avoid any sharp turns or kinks that might compromise the efficiency of the system. Flexible ducting needs to be properly supported too. Connections need to be properly fastened and sealed to prevent leakage, especially where flexible and rigid ductwork meet.
Your choice will ultimately be down to the type of system. Flexible ducts are best for relatively short runs, but when designing a complete air distribution system, metal duct work may be preferable and worth the extra planning and expense involved.
Like many specialist areas, silicone manufacturing has its own lexicon of key words and jargon that is useful to know. Becoming acquainted with this doesn’t just give the brain matter a work out but makes discussing all things related to silicone much easier.
The term silicone refers to a particular group of polymers – a large molecule of repeating units – with a silicon and oxygen spine, and organic (in the chemical sense) groups bonded with the silicon. Silicone is versatile as it is stable and resistant to extreme temperatures and conditions. A silicone elastomer is made up of silicone polymers that have been cross-linked to give them an elastic quality. Silicone rubber is a silicone elastomer that is used in a variety of industries. It can also be used for home repairs in the form of a setting, mouldable rubber called Sugru. To learn more about Sugru, see this report from The Guardian.

Vulcanisation is the process by which polymers are cross-linked with heat to give them special properties and more durability. Compression set is the measurement of how well a silicone material can recover its original shape after being compressed. The more closely it returns to its original thickness, the more ability it has to resist being pushed out of shape by external forces.
Silicone material is a term that encompasses silicone rubber, sponge and sheeting. Silicone sheeting is produced by a process known as calendering. Silicone foam can also make sheets and gaskets that are used for sealing, insulating and protecting in many industries. Silicone hose is also used in many industries, including automotive, aeronautical and marine, where reliable high performance is required. If you want to find out more about quality silicone hose, it would be a good idea to get in touch with a reputable supplier such as https://www.goodflexrubber.com/pages/silicone-hose-manufacture.
Silicone has a wide variety of applications and can be engineered with a range of additives to exhibit many different and useful properties. It can even be cured with platinum or manufactured to high standards of purity for use in food industries. When produced to high specifications, silicone can be used for medical purposes, and its sterile, durable qualities make it an excellent choice when long-lasting materials that do not react or become contaminated easily are needed.
At the beginning of the year, we learned about Samsung’s commitment to smart appliances so that in the future, not so distant, they could be common in our kitchens. Refrigerators and washing machines connected, although their date of arrival to the market was unknown.
But little by little we know details and so today it is the turn of the new family of washing machines of the Korean firm. This is the Samsung QuickDrive 8 Series, some washing machines that Samsung brings and that are a whole technology cluster. Some washing machines that are integrated into the QuickDrive family and that have been presented. » Read more
A few days ago we knew the official sale prices of the new range of Sony LCD-LED TVs for this 2018, the XF90 and XF85 models, with a zone lighting system FALD in the case of the XF90 that promises to keep the good impressions left by last year’s model. » Read more
The sector of robot vacuum cleaners is populated by dozens of alternatives, which are usually divided into two different ranges. On the one hand there is the entry range with cheaper models, while on the other hand we have a high range with much higher prices, but with a greater number of technologies and innovation.
Today we are going to analyze one of these high-end vacuum cleaners, the Botac D5 Connected from Neato, which has been the flagship of the company until the presentation of the D7 Connected a few months ago at the IFA 2017 in Berlin. We have been testing him for a few weeks to see what his weapons are to make a place in your home over his eternal rival, the Roombas of iRobot. » Read more
Thinking about using LED lights at home? These preliminary considerations can be useful to get more out of the change
Little by little we have seen how LED lighting (Light Emitting Diode or semiconductor diode that emits light when crossed by an electric current) has been conquering our homes. We have been abandoning the use of the traditional light bulb that first gave way to lighting by means of energy-saving light bulbs, which in turn has gradually given ground thanks to the push of LED-type luminaires. » Read more
It is one of the devices that most interest uncover among users. We speak of cleaning robots, a range of products that we have a good range to choose from. Here we have seen some of the most interesting models and features that we must control before we get one. A catalog in which LG wants to stand out with the LG Hombot Square Turbo.
It is the robot vacuum cleaner which apart from offering cleaning functions independently allows us to control our home thanks to the inclusion of a video surveillance system. For this the LG Hombot Square Turbo has a Dual Camera Dual Eye to monitor our home. » Read more
