Unscrew the faucet there is hot water, residents can be as long as the credit card consumer hot water, overhead collector set, still lush rooftop garden … … November will be "opened its doors," the Guangzhou Asian Games City, 89 buildings, more than 8,000 suites , provides 24-hour hot water, all from solar energy.
Although experts predict, the mainstream of the future family with hot water will come from solar energy. However, solar hot water into the homes of ordinary people still face price, installation and policy three major "bottleneck." Park as a future living "model", the Asian Games City is how to solve these challenges?
Difficult one: the risk of illegally built
At present, solar energy use problems encountered on several fronts: the installation of solar water heaters sad "plan off." According to the relevant provisions of urban planning and construction, building roofs are common residents of the whole building site, are not permitted to increase the common parts of the self-use equipment, no planning, "Zhunsheng Zheng," On the roof without permission is illegal construction of solar installations. Second, the size of the collector, installation, lack of uniform standards, if you wait until after the completion of the building, in addition to the installation, to bring more security risks building and landscape damage; private owners installed on the roof of the "pot cover ", if not installed lightning protection devices, may become the largest" lead mine accomplice. "
The solution: integrated design to be built
I boarded the Asian Games Town Technical Officials Village, Building 10, the roof, I saw 6-meter-high steel frame erected on the roof, vacuum tube solar water heater collector panels on a steel frame above the shop, like the natural sun visor, and roof design seamless. The use of aerial design, solar water heater collector panels do not take up the roof area, roof of the "Hanging Gardens" is still lush. Floor surface of the hot water pipes with a special material "package" will not burn people at the rooftop leisure and play.
Residential toilet, a bath without water heater like the hotel as long as they have twisted the faucet of hot water. Some devices are equipped in each household a total of six rooms in the water, impurities in the water supply, respectively, high-quality water and domestic hot water, watering, bathing, cooking can take what. Including hot water pipes with a special smart meter, residents can be as long as the credit card consumer hot water.
"We are in the construction bidding program on the use of integrated design of solar systems, together with the construction program to be built, and designed with a roof of heavy computing loads, water requirements, plus a lightning protection device to avoid a one as each installation, the housing function may cause varying degrees of damage and the risk of illegal construction. "Guangzhou Asian Games City solar project leader Luo Huiying said.
Problem 2: the high price
High prices of solar water heaters, it has become into family s threshold. I visited the city several large appliance stores, find rare solar water heater "shadow." Suning Appliance, a sales official said, in the city s water heater market, energy water heater accounts for 2 / 3, the remaining 1 / 3 is basically a gas water heater, solar water heaters in the city basically no market share. It is understood that an ordinary gas or electric water heaters up and down the retail price is generally in the thousands, or even three or four hundred dollars of promotional items, while the price of the basic brands of solar water heaters are more than 3,000 yuan. "Although solar and energy efficient and environmentally friendly, installed after no electricity, but its first investment is a bit high." Aunt West side neighborhood off some frustration.
