Description
Brief Introduction
The characteristic of vacuum solar collectors is that they have a
higher efficiency level in autumn and winter than standard flat
surface collectors; the efficiency of these collectors is lower
than flat surface system in summer. Vacuum collectors are
particularly suitable to integrated with low temperature room
central heating like wall or floor systems or also for high
temperature. The characteristic of vacuum solar collectors is that
they are made of vacuum glass tubes with a high efficiency
selective
coating; the central part of these tubes’ is entirely of copper.
The basic characteristic of these panels is that they have a curved
transparent absorbent surface that allows collectors that are not
positioned perfectly towards south to offer the same results as if
they were.Heat pipe solar collector adopts the interferential
coating technology for a high-efficiency absorbing layer, with
features of resisting high-temperature and high-coldness, high
efficiency in absorbing energy. The inner part adopts heat pipe
structure, thus there is no water in the tube, and there is no
scale, which can avoid the breaking of the tube, extend life
span.
Working principle
vacuum tubes absorb and convert the sunlight into heat energy which
will be transferred to heat pipe by fins, and then the medium
dissipates the heat at the cooling end of the tube, exchanging heat
with the medium in the inner vessel. In this way, it heats the cool
water into hot water
gradually.
Features
â—Working under high pressure
High pressurized technology makes the installation level
unrestricted. Hot water is supplied under pressure to ensure large
flow and comfortable bathing. There is no water in the tube, so
there is no scale, no breaking and it is higher in anti-freezing
and safer in use.
â—Heat pipe technology
Heat pipe technology means that the collector can work at low
initial temperature with features of faster heat transference and
higher efficiency.
â—Integrate with the building
The collectors separated from water tank makes solar water heaters
combine with buildings perfectly.
