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.
