What is solar thermal technology?The
conversion of solar radiation into heat for technological use
as a pre-heating system. Solar thermal heating is applied to
water, air or structural materials. Conversion of light to
heat can be achieved through passive systems or active systems
(mechanically transferring heat by means of a working fluid
such as oil, water or air).
Real world usageSolar thermal technology can be
implemented wherever water needs to be heated. Nurseries,
hospitals, schools, or any campus environment where boilers
are installed are prime candidates for implementation of our
unique commerial/industrial integration capabilities. By
preheating the water with super-efficient solar thermal tubes,
utility costs for running the boiler are reduced heavily as
the water comes into the unit pre-heated.
production benefits from solar thermal technology as well. By
heating the water with solar, less gas has to be used to heat
the water that is used in the boiler. A two fold benefit
occurs: 1) more gas can be sold instead of used to heat water,
2) the boiler stack's emissions are proportionally reduced.
This makes permitting much easier with regulatory agencies
such as the APCD.
Which components do we use?Established in December
1995, Beijing Sunda Solar Energy Technology Co., LTD. is a
hi-tech enterprise affiliated to Beijing Sunpu Technical
Company, engaged in developing, manufacturing and marketing
various evacuated tube solar collectors. With a production
base of annual productive capacity of 500,000 tubes, Sunda is
one of the largest heat pipe vaccum tube enterprises in the
world. Sunda has opened a new enlarged manufacturing facility
and established an overseas subsidiary company in Germany.
TechnologyThe vaccum tube solar collector with heat
pipe is a breakthrough in solar technology. To achieve the
highest efficiency the absorber is sputtered with an aluminium
nitride selective coating, which transforms over 92% of the
incoming solar radiation into heat. The heat pipe transfers
the heat into the heating circuit via a copper condenser. In
order to prevent any heat loss the absorber and the heat pipe
are mounted in a highly stable vacuum glass tube, which
ensures a good insulation and protection in the long term
against corrosion and other environmental influences.
The collector therefore combines a high efficiency of
the absorber with the advantages of durability and a long
lifetime. It is easy to install and guarantees optimal
service, comfort and reliability. All products are inspected
and certified according to the German Industry Standard DIN
ResponsibilityThe active use of solar energy does not
only contribute to saving money, but also helps to conserve
the Earth, since the substitution of fossil energy sources
reduces the generation of harmful substances and carbon
dioxide affecting the climate equilibrium.
collectors are being proven efficient andreliable over a long
lifetime. For the worldwide applications of solar collectors
in the heating system, solar air-conditioning plants, solar
powered process heat, desalination plants and other
applications, the economic advantages go hand in hand with the
sense of responsibility for the environment and future
