Products Expo understand the idea of future green house heat pump – heat pumps, solar energy, new energy – heat pump industry
Building cells that form the city, the family constitutes a social cell, the intersection between the two is that love build office?? Home.
Products Reading Expo Urban Best Practice Area, the future home look as if your fingertips: if the wall will light, if the window will generate electricity to run if the house chasing the sun … … when so many pictures of real, if a front, our only a marvel.
Home of human beings as energy source
A hot summer, lived in “H2O” Mr. Schneider collated packing, direct Quwang in the same building to work within the company. Mr. Schneider’s office has no air conditioning facilities, but room temperature is very pleasant, the air quality is also good. This is a unique air circulation system in the housing to play a role: in the artificial space created after the relative isolation, without using any heating or air conditioning will be able to maintain a comfortable indoor temperature and the environment, be warm in winter, cool in summer.
Mr. Schneider’s office has a large number of electrical appliances, but not by using the energy grid, but from solar, geothermal, electrical work, heat, and even Mr. Schneider itself. In addition to solar power and geothermal heat pumps, housing hot and cold air can also be used to exchange for energy, electric heat and therefore the heat the house staff, have been converted into electrical energy.
Area E is located in the Expo
Urban Best Practice Area of Hamburg Hall “Hamburg House” is located in Hamburg, the port to Pier 60 New Salmonella’s “H2O” as a reference copy of the parent, school, called “passive house” one almost without external power supply housing, the required energy generated by the housing itself.
Interpretation: At present, home decoration in general to achieve energy self-sufficient yet possible, however, we should be in the wall of thermal insulation, electrical energy conservation and emission reduction more attention, both meet environmental requirements, but also actually saves the cost of daily use.
If the south side of the roof to install six solar collector panels that generate electricity 65% of the entire family can meet energy needs
House chasing the sun Best practices in urban areas, there is an inconspicuous gray and white four-story house, this is the case of Shanghai Museum “in Shanghai? Eco home.” “In Shanghai? Eco home” is the sole representative of the Shanghai World Expo exhibitors physical case project: “in Shanghai,” Shanghai represents the item based on the local community, for Shanghai’s geographical and climatic conditions tailored; it 60% of building energy efficiency than similar above, to “ecological” word-deserved; and “home” represents the design team will bring the audience the feeling of “eco-technology” optimization under “house car” warmth and comfort of life itself.
Into the porch, the old Shanghai architecture in the alley, courtyard, dormer windows and other design greets, these traditional lighting, ventilation systems play a role in reducing energy consumption. In the bathroom, cleaned up the waste water will no longer be directly discharged into the sewer, but is used to flush toilets. According to fluid mechanics “embedded” in the entire building into the “eco-nuclear,” the wind on all sides to “optimize”, and through the plant filter cleaning system, making the indoor air flow to keep clean. “Eco-core” design opening and closing the top of the roof, natural ventilation at the same time to strengthen and increase the effects of indoor lighting. Roof installation “chasing light shutters” can follow the sun angle changes automatically change the angle, on the one hand to play the role of shade, on the other hand reflected ambient light, improve the indoor illumination; not lighting up in indoor light, standard, automatic shutter curtain adjustment, while interior lights will automatically turn on. The old brick building of the “breathing wall” of advanced design for the building wall to put a layer of “air flow” underwear, can reduce the radiation temperature of the wall, play a role in regulating the indoor temperature.
“Eco home” in one of two potential energy recovery lift elevator, between the up and down, the resulting “potential” can be stored; the other is speed elevator, elevator passengers according to how much control elevator speed.
Easy removal of the replacement building exterior planting, modular plants, such as fresh and pleasant nature. These plants need special care for people, intelligent device control “drip irrigation” technology will be based on the amount of water required for plants to carry out a purpose, “drip”, with a minimum of water to plants, “Hey,” just right. Wooden roof is made of bamboo suppression, bamboo growth cycle is short, easily drawn, to avoid the consumption of timber resources.
Interpretation: given human nature, many gifts: wind, sun, plants … … want to do is make good use of their humanity rather than to endlessly grab. The market appears more and more solar energy products, ground source heat pump products, we may consider more choice, not one-sided pursuit of upscale and luxury materials.
Dishes can be eaten “In Shanghai? Eco home” side of two villa-style building, is a zero carbon Expo Hall. “Zero Carbon Museum,” a prototype from the world’s first zero-carbon community?? Beddington, south London, a “zero carbon” community, but the museum is located in Puxi Park zero carbon building all drawn from Shanghai.
Zero Carbon Museum full use of natural factors. For example, diversified use of solar energy, so not only for power generation, heating, also with the passive wind and ground source heat co-driving the indoor air, adjusting temperature and humidity inside; roof color hood 22 can be flexible with the wind rotation temperature and pressure and the pressure to use the fresh air stream to enter each room, and indoor air emissions. Also use solar energy and the Huangpu River water to enter the interior of the new air cooling dehumidification; use of wood waste generation and to create hot water, use of food and organic waste fermentation biogas energy.
With the “in Shanghai? Eco home”, like, zero-carbon building materials Museum of fully turning waste into treasure, The walls of the cement mixed with 50% of construction waste, it uses the whole insulation strategy. The walls are built with insulating materials to reduce the outdoor heat penetration, absorb excess heat indoors, stable indoor temperature fluctuations.
Zero Carbon Museum of tableware can actually eat these dishes are redundant with the end of business day, organic cookies, made of specially treated. Guests to drink the remaining bottles are also collected and stores, made the shop ceiling, floor lamps, candlesticks and other decorative.
Interpretation: Of course we can not ask the home decoration made of edible materials are, however, in the decoration process, we can still use their brains, greater use of discarded furniture and other items, make the best
The Workings of your Bike’s Gears
The gears in mountain bikes just keep getting more and more intricate. The bikes of today have as many as 27 gear ratios. A mountain bike will use a combination of three different sized sprockets in front and nine in the back to produce gear ratios.
The idea behind all these gears is to allow the rider to crank the pedals at a constant pace no matter what kind of slope the bike is on. You can understand this better by picturing a bike with just a single gear. Each time you rotate the pedals one turn, the rear wheel would rotate one turn as well (1:1 gear ratio).
If the rear wheel is 26 inches in diameter, then with 1:1 gearing, one full twist on the pedals would result in the wheel covering 81.6 inches of ground. If you are pedaling at a speed of 50 RPM, this means that the bike can cover over 340 feet of ground per minute. This is only 3.8 MPH, which is the equivalence of walking speed. This is ideal for climbing a steep hill, although bad for ground or going downhill.
To go faster you’ll need a different ratio. To ride downhill at 25 MPH with a 50 RPM cadence at the pedals, you’ll need a 5.6:1 gear ratio. A bike with a lot of gears will give you a large number of increments between a 1:1 gear ratio and a 6.5:1 gear ratio so that you can always pedal at 50 RPM, no matter how fast you are actually going.
On a normal 27 speed mountain bike, six of the gear ratios are so close to each other that you can’t notice any difference between them.
With actual use, bike riders tend to choose a front sprocket suitable for the slope they are riding on and stick with it, although the front sprocket can be difficult to shift under heavy load. It’s much easier to shit between the gears on the rear.
If you are cranking up a hill, it’s best to choose the smallest sprocket on the front then shift between the nine gears available on the rear. The more speeds you have on the back sprocket, the bigger advantage you’ll have.
All in all, gears are very important to mountain bikes as they dictate your overall speed. Without gears you wouldn’t be able to build speed nor would you be able to pound pedals. The gears will move the pedals and help you build up speed.
There are all types of gears available in mountain bikes, all of which will help you build up a lot of momentum if you use them the right way.
