Heat pipe pressurized solar collectorÂ
Features:
The system could be mounted on the southern roof of the villa，on
the courtyard lawn, or the southern slope of the construction. The
hot water could be delivered to any floor without limitation. The
system has adopted the forced circulation (automatic control) work
module to control the temperature automatically and deliver water
by pressurization. So it has solved the long time inconveniences of
manual operation. The system only needs small amount of investment,
and it's easy to handle. Moreover, it's safe, convenient and energy
saving, causing no pollution to the environment, so it's
complemented as Green Project by the experts.
Â
The composition of the system：
The solar water heating system is consisted of solar collector,
heat preservation water tank, solar power workstation and the pipe.
The solar collector is consisted of super conducting vacuum heat
collecting tube and header, so it's of great efficiency of heat
collecting. The absorbing percentage of the glass vacuum collector
is more than *4%. In the sunny days of spring or autumn, each
collecting tube could make the water up to *0℃only in 2.5 hours.
The water tank uses SUS **4 2B stainless steel as internal bladder
and polyurethane integral foaming as heat preservation material to
improve the heat preservation ability. And it makes the system be
used as usual under minus *0 ℃. The high corrosion-resistant and
good heat preservation PPR pipe is used as the system's pipe, so it
adds the good efficiency and long service of the system.Â
The principle of the system：
1.The collector applies the fourth generation of solar
collector**-heat pipe vacuum collector to transfer the solar power
to heat energy.
2. When the temperature of TC(the temperature of the collector) is
higher than that of TR(the temperature of the water tank), the
controlling device will start the circulating pump.
3. The circulating pump makes the working medium circulate in the
system.Â
4. The heat is transferred from the heat collector to the water
tank by the heat exchanger
5. During the working process of the circulating pump, when the
temperature difference is less than a set point, the circulating
pump will stop.Â
6. When TR (the temperature of the water tank) reaches the highest
of set point, the controlling device will close the circulating
pump.Â
7. The electrical heating device will automatically make the
temperature of the above part of water tank stay at the set
point.
Â
The characteristics：
1. The collector and the water tank are separated, and the system
runs under the forced pressure.Â
2. The controlling device is specialized, so the system runs
automatically.
3. The water tank can be installed anywhere.
4. The heat pipe vacuum tube collector is two circuit system, free
of freezing and could be used all year.
5. The metal super*- conducting vacuum heat collector is used, no
water in the tube, no bursting and could be used as usual under
minus*0℃.Â
6. The water tank applies with the enamel internal bladder, runs
under pressure.
7. Provide the water at the same temperature, set the highest
temperature, heat the water at set point by electricity, protecting
the data when power off, supply the hot water *4 hours a day.
8. The system is designed separately, in harmony with the
structure.Â
9. The heat collector could be mounted on the balcony veranda, the
southern wall, sloping roof or awning.
*0. The system is designed as unit, convenient to transport.
The characteristic of each part：
1.Heat collector: Sectional metal vacuum heat pipe collector.
2. The water tank: Enamel internal bladder electrical water
tank.
3. The circulating pump: UPS system imported from Germany, energy
saving, low noise and long service.Â
4. The frame of heat collector and the water tank.
5. The controller: imported from Germany, stable and complete in
function.
6. The workstation: The main parts are imported from Italy to
ensure the safe and reliable running of the closed system.
7. The pipe: the copper tube is suggested.
8. The heat preservation material.

◎Low temperature resistance: no breaks at**0℃
â—ŽHeat impact resistance: no damages after over 3 times'
alternative impacts of cold water below *5℃ and hot water over
*0℃.
â—ŽPressure resistance: can withstand 0.6Mpa.
â—ŽHail resistance: no damage by the impact of Φ*5mm hail.
â—ŽAppearance standard: the color of the selective absorptive
coatings should be even, and the coatings should have no wrinkles
and peelings. The allowed tolerance of borosilicate glad glass
tube's diameter should be in accordance with ISO***3:***8.camber of
the borosilicate glass tube should be no more than 0.3%.The
translation the borosilicate glass tube, which is ****0mm away from
flange end, should be round. The ratio of the longest to the
shortest radial dimensions of the borosilicate glass tube should be
no more than 1.*2.
Water Tank:
1.Polyethylene insulation with a fabric casing can be used if
polyurethane insulation is not suitable.
2. Tanks are designed for high pressure that direct connection to
mains pressure water supply is permitted.
3. Direct connection of copper coil HE to mains pressure water
supply is permitted.Â
4. In most regions, only locally approved heating elements can be
used. The heating element port can be made as customers required to
suit any sized element. (Female thread-located in top of tank).A
sample of the heating element will need to be provided before tanks
are manufactured in order to.
