The sun energy management with new business opportunities


Reporters learned from the Province of solar products quality inspection center, Haining being developed vacuum tube solar air collector applications. "There is in the research and development stage, distance production still time." Said Shen Bin, the person in charge of the center.

It is understood by solar panel energy to produce hot air and applied to agriculture and industry, are not uncommon. In Yunnan, with a solar hot air production of dried flowers; applied to agriculture were in the north, solar heating, to fruit and vegetable greenhouse temperature control. "But they are flat-plate collector. Haining vacuum tube industry based on breakthrough vacuum tube solar air collector, good news on the whole industry." The staff of the center, and flat-panel sets heat compared to the higher temperatures generated by the vacuum tube collectors, can reach 40 to 110 ° C, but the main problems of the current research and development in that hot air and how smoothly Export.

Vacuum tube solar air collector can use to areas of daily life? In this regard, the staff explained, require relatively large lighting area to produce enough hot air, consider installing units with such conditions. "As long as the hot air directly access the central air-conditioning pipes on" Development and application of vacuum tube solar air collector has become a key research projects in Haining.

Solar energy contract management or with new business opportunities

In August last year, days (Holdings) Co., Ltd. Haining Leather City signing the contract energy management mode, "lineup" Leather City, one, two, and four of the building roof, roof power projects put into use after a year will generate 3.5 million kwh, the annual savings of about 1490 tons of standard coal.

According to insiders, printing and dyeing enterprises in Jiangsu and other places, plenty of solar energy management contract. Printing and dyeing enterprises no longer rely solely on the boiler to boil water, but through the solar equipment needed for the production of hot steam and hot water, reduce emissions, and the the saved emission rights indicators can be used to transfer, but this practice is not in Jiaxing . Jiaxing solar cell hot water and hot air applications might be able to introduce energy management contract, and the resulting new business opportunities.

Split solar water heater detection method

With the increase in high-level, high-rise residential building integration is mentioned more and more times, including building integrated solar hot water systems.

Common Building Integrated Solar Water Heater is hanging in the balcony of a flat-plate collector, water tank installed in the bathroom or balcony. In addition, focus on flat plate solar collectors installed on the roof and a large water tank and hot water are supplied to households.

A few days ago, Zhejiang University, Zhejiang Provincial Energy Research Institute and other units expert review by the assumed building integrated the provincial solar products quality inspection center, the small inclination split solar hot water system detection methods research. This detection method is a study on the relationship between households balcony on the tilt angle of the flat-plate collector and the water tank capacity, is the optimal ratio between how with both households most hot water, and does not affect the architectural aesthetics. This detection method is a useful reference for the future design of integrated building.

"Flat-plate collector intolerance frozen in Guangdong and Yunnan, more than building integrated solar water heating system in the province, the research and development of the flat-plate collector production started late." Bin Shen said.

Well, common household vacuum tube solar water heater winter weather to how to care for it? Shen Bin,, install master is able to do basic vacuum tube connector is not blocked in prison and warm, do not worry the vacuum tube will be the cracking.

In addition, if the public found the home solar water heater overnight temperature declined by more than 10 ° C, it is recommended to check the tube has been discolored. If discoloration on looking for the master to a trim.

More than 130 enterprises in the province to complete the record of energy efficiency labeling

Home solar hot water system energy efficiency labeling rules implemented last August. "GB" requirements, the volume of hot water storage tank must be attached to the the legitimate energy efficiency labeling to sell home solar water heater products below 0.6m3. Affected, Haining City and the surrounding areas hundreds of solar companies need to be completed within a short time the production of energy-efficiency labeling and filing.

Reporters from the provincial solar product quality inspection center was informed that there are more than 140 companies through the completion of the center energy efficiency labeling for the record, of which more than 130 enterprises in the province.
