Insulation was first invented by Sir James Dewar in 1892 it has been
used for insulating everything from sub-cooled liquid helium at near
absolute zero to hot coffee in a Thermos bottle.
Performance and economic advantages of vacuum insulation have been
realized in many industries and applications for decades.
It is an
advanced thermal insulation technology that significantly outperforms
conventional materials such as foam or fiber.
two different ways to design a building component using the principles
of vacuum insulation: on the one hand the load bearing vacuum insulating
sandwiches with its envelope made of stainless steel and on the other
hand the vacuum isolation panels with its envelope made of a multilayer
for producing vacuum insulation systems comprising at least one
insulation layer which is surrounded by a casing, wherein the gas
pressure in the insulation layer can be reduced by means provided in the
component, wherein the means for reducing the gas pressure is embodified
property of vacuum insulating elements used in building constructions is
its resistance against mechanical loads and impacts.
Prefabricated vacuum insulated piping has been used for nearly 50years
in critical applications for transferring liquid helium, liquid hydrogen
and many other cryogenic liquefied gases.
material used in the construction of vacuum insulation panel plays a
very important role in the thermal performance, mechanical properties.
Commonly used materials are precipitated silica and nanogel.
panel insulation, whose insulating properties are superior to
polyurethane foam, would greatly reduce heat transfer in storage water
insulations are a promising solution for small thermal long-term
storage.The performance of vacuum insulation is known not to be much
affected by the cryogenic cooling.
thermal insulation system called vacuum insulation panel (VIP) is a very
promising technology to decrease the energy used for buildings, heating
insulation has a thermal resistance about eight times higher than the
same thickness of traditional fibrous insulation.
insulation panel is made by a micro or Nano-porous core material in a
vacuumized environment retained by a barrier with low permeability.
of Vacuum Insulation produces particularly high 'R' values, low self
weight and eccentricities, good environmental credentials in terms of
materials usage, possible improvements in acoustic performance.
of vacuum insulation can reduce the wall thickness by about 50%.Vacuum
insulation is a high efficient but also expensive material for the
thermal insulation of the building envelope.
