Capillary Tube Mat
A capillary tube mat is a flat composite structure of thin tubes (capillary, capillaries) with a distributor tube and a collector tube. The main applications include cooling ceilings (radiant cooling) and underfloor heating. Technology Idea The construction of the capillary tube mat models the networks of fine veins created by nature, which run under the skin (surface) of living creatures, and supply the organism with nutrients and also help heat regulation of the body. Capillary tube mats lay close beneath the surface in areas of rooms, and transport warm or cool water through them in order to control the temperature of the rooms. Since fluid always flows in parallel through many capillaries, similar to the veins under the skin of the body, the heat exchange with the environment is intense and energetically effective. A room whose temperature is controlled by the use of capillary tube mats as a surface heat-exchanger requires flow temperatures for heating or cooling whic ...

Capillary
A capillary is a small blood vessel, from 5 to 10 micrometres in diameter, and is part of the microcirculation system. Capillaries are microvessels and the smallest blood vessels in the body. They are composed of only the tunica intima (the innermost layer of an artery or vein), consisting of a thin wall of simple squamous endothelial cells. They are the site of the exchange of many substances from the surrounding interstitial fluid, and they convey blood from the smallest branches of the arteries (arterioles) to those of the veins (venules). Other substances which cross capillaries include water, oxygen, carbon dioxide, urea, glucose, uric acid, lactic acid and creatinine. Lymph capillaries connect with larger lymph vessels to drain lymphatic fluid collected in microcirculation. Etymology ''Capillary'' comes from the Latin word , meaning "of or resembling hair", with use in English beginning in the mid-17th century. The meaning stems from the tiny, hairlike diameter of a capi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiant Cooling
Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels",ISO. (2012). ''ISO 11855:2012—Building environment design-Design, dimensioning, installation and control of embedded radiant heating and cooling systems''. International Organization for Standardization. "embedded surface systems", "thermally active building systems", and infrared heaters. According to some definitions, a technology is only included in this category if radiation comprises more than 50% of its heat exchange with the environment; therefore technologies such as radiators and chilled beams (which may also involve radiation heat transfer) are usually not considered radiant heating or cooling. Within this category, it is practical to distinguish between high temperature radiant heating (devices with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underfloor Heating
Underfloor heating and cooling is a form of Heating, ventilation, and air conditioning, central heating and cooling that achieves indoor climate control for thermal comfort using hydronics, hydronic or electrical heating elements embedded in a floor. Heating is achieved by Conduction (heat), conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods. History Underfloor heating has a long history back into the Neoglacial and Neolithic periods. Archeological digs in Asia and the Aleutian islands of Alaska reveal how the inhabitants drafted smoke from fires through stone covered trenches which were excavated in the floors of their subterranea (geography), subterranean dwellings. The hot smoke heated the floor stones and the heat then radiated into the living spaces. These early forms have evolved into modern systems using fluid filled pipes or electrical cables and mats. Below is a chronological overview of under floor heating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

2010 Olympic Village
The Vancouver Olympic Village (VVL) is a neighbourhood and Olympic Village built by Millennium Development Group in Vancouver, British Columbia, Canada, originally built for the 2010 Winter Olympics and 2010 Winter Paralympics. The site is located on the shoreline at the southeast corner of False Creek, north of First Avenue between Ontario and Columbia Streets. Boasting over a thousand units, ranging over a million square feet, the Village was able to accommodate over 2,800 athletes, coaches, and officials for the 2010 Winter Olympics. Following the Olympics, the accommodations became residential housing. Today, the Village is a mixed-use community, with approximately 1,100 residential units, area parks, and various retail and service outlets. Southeast False Creek is the neighbourhood development that was built around the Olympic Village and in which the Village now sits at the core of.

Uniqa Tower
The Uniqa Tower (owner's spelling: ''UNIQA Tower'') is an office building on the Danube Canal in Leopoldstadt, the 2nd district of Vienna. The building received the European Union ''Green Building'' label. It is the first building in Austria and one of the first buildings in Europe to bear the label. Architecture The tower is 75 meters high, has 21 upper floors and five basement floors. The shape of the floor plan is a stylized ''"Q"'', as it corresponds to the logo of Uniqa Insurance Group located in the building. The more than 7,000 square meter facade was designed as a media facade with a dot matrix of LEDs. It consists of more than 40,000 pixels, based on approximately 160,000 individual LEDs. The system works on a video component basis with 25 frames per second. The concept was provided by the lighting design office ''Licht Kunst Licht'' in cooperation with the German media artists Holger Mader, Alexander Stublic and Heike Wiermann. The technical implementation was carried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
